Anchor: Namaste, friends. In the last episode of ……………..you heard that… (Recap of the last
episode). In this episode we will talk food adulteration, methods by which you can detect it by
the meagre means available in your college’s chemistry laboratory and the laws and litigation
regulating it.


Are you purchasing sweets, milk or other edibles…well tell me one thing, are you sure that
these are pure and unadulterated? This question always flashes in every one’s mind, while
purchasing edibles from the vender, shopkeeper or even from reputed shops. This is a global
problem. Really this is a part of general deterioration of the society. People do not hesitate in
mixing even those items in the food products which are not only injurious to human health but
at times fatal also. Every day we read in news papers, listen on radio or see on television the
news of food adulteration and people getting sick or even dyeing from it. In preview of above
information, it becomes necessary for us to know about unfair trade practices in food business,
their effects on human health and much more.

                                              Scene-1
Place- Drawing room in Medha and Vivek’s house.
Time- Morning
                                        (Medha is sitting along with her papa, waiting for tae)
Papa- Medha, switch on the television… let me see what is the morning news, till your
mummy brings tae.
Medha- Good idea papa but don’t drag mummy in between…… I know her tae is ready
                                   (Medha switches on the television. After initial disturbance,
                                                           voice of news reader becomes clear)
News reader (female) - Breaking news…… our local correspondent from….. Area is
reporting that 36 peoples from this area fell sick after consuming adulterated mustered oil…


                                                                                               1
24 people have been referred to the hospital, condition of four of them is reported to be
serious. Our local correspondent Harish Rawat is present in the hospital compound……
Harish how it happened…..
             (Rest of the conversation between news reader and correspondent in background,
                                conversation between Medha and her papa becomes apparent)
Medha- Damn it….. it is every day’s story……. pulses are adulterated…… milk is
adulterated…… oil is adulterated with urea…… you can hardly find an object which is pure
for sure….. what to eat now….. how to survive?
Papa- …………..of course Medha morality of society has gone down to drains. Dishonesty
prevails every where. I say this is in every field, in every business. This is a general
deterioration of our society.
Medha- People are so ruthless and money minded that they don’t even think once before
mixing those items in food products which are not only deleterious to human health but are
talking many human lives every day.
                                                                 (Footsteps, Vasudha enters)
Vasudha (from distance)-……but still there is one thing which is still unadulterated……
hundred percent pure……
Papa- What is that Vasudha?
Vasudha- My love…..
Medha- ………..of course Mom.
Papa- …but I smell some adulteration in this too. Initially it was for me only but now……..
(Laughs)
Vasudha- …………jealous of my children?
Medha- papa!
Vasudha- So this non adulteration tae is here added with extra love for you all (Laugh)
Papa- I doubt…….
                                                                     (Foot steps, Vivek enters)
Vivek (from distance)-…………….. doubt….. in what papa?
Medha- Think of devil and devil is here.
Vivek- bla…..bla….bla…… who cares? Papa you were talking about some doubt………..
Papa- Your mother said that in this era of adulteration she has prepared this unadulterated tae
for us with added love.
Vasudha- of course…….



                                                                                             2
Papa- Agreed……. but can you guarantee that tae which you have purchased from the market
is pure and not a mixture of used and recoloured tae leaves.
Vasudha- Oh yes, that can not be ruled out……
Medha- Mom today also there is news on T.V about adulterated mustered oil.
Papa- ……and it has taken 4 lives till now…. Many more are in the hospital.
Vivek- Really a matter of concern…….
Papa- Vasudha, I am seriously thinking that this year we will not purchase Khoya from the
market.
Medha- Why Papa?
Papa- On Deepawali every one purchases Khoya from the market……
Vivek- So what?
Papa- with increased demand there are very little chances that we can get pure Khoya.
Vasudha- People do mix many things in Khoya from, minced potatoes, vegetables, arrowroot
to many dangerous and even inedible things.
Vivek- There is an idea.
Medha- I bet this will be another nonsense…. ok…. shoot.
Vivek- We can purchase milk from milk vendor or local milkman and prepare Khoya
ourselves.
Medha (Taunting) - What a great idea from an original thinker……..
Vivek(with pride) - of course…..
Medha- Don’t you remember that few months back a milk adulteration racket was unearthed
by the authorities?
Vasudha- yes those people were manufacturing artificial milk with urea, refined oil and soap.
Papa- Horrible….
Vivek- It means no sweets on this Deepawali. This is more horrible…….. Is there some other
alternative?
Medha- yes there is one…….
Vivek- Which one Medha?
Medha- Leave you studies, purchase some buffaloes and feed them……….. clean their dung
wash them and then milk them…. and then prepare Khoya that will be pure for sure….. isn’t it
mom……(Laughs)
Vivek- Keep your idea with you, it suits you. Later me and papa both will marry you it a
milk man…….
Medha- (Irritated) Listen mom….


                                                                                            3
Vasudha- don’t fight…… calmly sip your tea.
Papa- Vasudha, I am thinking what is to be done for this food adulteration?
Vasudha- Yes, you need everything for your survival…… can you leave drinking milk……
cooking pulses……. flavouring your vegetables…… adulteration is every where, it is
universal…..
Medha- It means we are destined to consume these harmful substances from these adulterated
food items.
                                                                                  (Doorbell rings)
Papa- Vivek, look who is on the door?
                                          (Vivek opens the door and shouts from their, excited)
Vivek- Dadda has come from the village……. (To Dadda) you are well in time Dadda,
steaming hot tea is ready, unadulterated and pure….. Ding dong…….
Dadda- (Coming in the room) you naughty devil hold this bag…..
Vivek- Bag? What is in it Dadda, some sweets for me?
Papa- Pranam Dadda.
Vasudha- Pranam Dadda.
Dadda- May God bless you….. God bless you both.
Vivek- Dadda there is big Tiffin box in your bag. What is in it, may I open it?
Dadda- Don’t get so impatient, give it to your mother. There is some Khoya in it…… Sagar
lalla your bhabhi gave this to me to give you. In cities getting pure Khoya is difficult that too
on festivals like Diwali.
Vivek- Dadda…. you are great…… let me touch your feet again….you are great…. you
rescued us in time….. otherwise papa had cancelled the programme of sweets on this
Deepawali……
Dadda- What is ths Sagar lalla, did you not plan to prepare sweets on this Diwali, why?
Sagar- Dadda, the type of Khoya we get on these festivals, is worth for nothing… grossly
adulterated with many edible or even inedible substances.
Vasudha- It’s better not to eat it…..
Dadda- Oh, you should have informed me, I could have brought more Khoya…. I mean in
sufficient amount.
Sagar- How many things you will bring from village…. every food item here is adulterated…
Dadda- Administration does not do anything?
Medha- Dadda they do at times but adulterers and are far ahead then these administrators.
                                                                               (Doorbell rings)


                                                                                               4
Vasudha- Medha, look who is there?
                                                                           (Medha opens the door)
Medha (fron distance)- Oh Gagan uncle, good morning……..
Gagan(entering) - very good morning Medha….
Sagar- Come…come in Gagan. This is my elder brother and Dadda he is my friend Gagan,
scientist in local “Public analysis laboratory”.
Dadda- Which lebatary….Sagar lalla?
Sagar(laughing)- Dadda….. no….no….. not lebatary…. laboratory where thing are
chemically tested…..
Gagan- Dadda, I examine the adulterated food items…..
Dadda- Oho…. So you are “Sample wala people” who takes sample of milk…
oil….pulses……. am I right Gagan lalla?
Gagan- not exactly Dadda…. Actually I examine these samples and decide that is this
particular object pure or adulterated?
Dadda- Gagan lalla, every thing is adulterated in your cities be it food items, things of daily
use or any thing………… water is adulterated here…..even air is adulterated.
Sagar (laughing)- No Dadda mixing of other harmful gases in breathing air is not
adulterated… this is called pollution, isn’t it Gagan?
Medha- Papa for a common man, if any food article contains any poisonous or other
ingredient which is injurious to health, is adulterated.
Vivek- Is this correct Gagan uncle?
Gagan- Correct but this is not the only criteria.
Medha- then…..
Gagan- Even if a food article contains any substance affecting its quality or of it is so
processed as to injuriously affects its nature, substance or quality; is called adulteration.
Vasudha- But my milk man mixes water in the milk, is it not adulterated?
Gagan- yes Bhabhi, if any inferior or cheaper substance has been substituted wholly or partly
for the article or even abstracted prom it.
Medha- As people remove cream from the milk…….
Gagan- yes, if this addition or abstraction, affects the quality of the food item or injuriously
affects its nature, it amounts to adulteration.
Vivek- Some time food vendors sell some rotten food items…….




                                                                                                5
Gagan- yes Vivek, if any food article consists wholly or in part of any filthy, putrid,
disgusting, rotten, decomposed or diseased animal or vegetables substance or being insect
infected………
Sagar- …means if it is any way unfit or injurious for human consumption, amounts to food
adulteration.
Gagan- Yes, even if a food article contains any prohibited colouring matter or preservative or
have these in excess than the prescribed limit, food deemed to be adulterated.
Vivek- Prohibited colouring matters, what are these?
Gagan- Studies have shown that many colours like Amaranth, Auramine, Blue VRS, Congo
Red, Fast red E, Green S, Malachite green, Metanil yellow and many more are known to
produce adverse effects in experimental animals.
Dadda- in our times for colouring sweets, we either use herbal juices or substances like,
saffron. But now a days artificial colours comes in sachets, are used.
Gagan- yes Dadda…… because these are easy and cheap….
Sagar- I think it is necessary to declare on the label of food item packet that it contains
permitted colours and flavour.
Gagan- yes Sagar that too in bold and legible letters.
Dadda- Is there any criteria for the standard for sellers of these food items?
Gagan- yes Dadda if the quality or purity of the food article falls below the prescribed
standard of the food article, it is presumed to be adulterated even if it is not injurious to health.
Sagar- I think there are some criteria for food packing and containers too.
Gagan- yes Sagar, if the container of the food article is composed of poisonous or deleterious
substance which renders it contents injurious to health, it also amounts to food adulteration.
Vivek- Gagan uncle why these food items are adulterated?
Vasudha- for easy and extra money……
Sagar- Some time these adulterants are added to make the food item attractive and hide the
inferior material, used in its production.
Medha- yes papa, many colorants and flavours are added in food items for this purpose.
Gagan- Medha these adulterants may also reach into these food items without bad intentions
of their manufacturers.
Sagar- ……….during storage, processing or packing.
Gagan- yes sagar, so common adulterants may be broadly classified as intentional, means,
deliberately added chemicals to disguise inferior commodities or to earn undue profits.
Vivek-….. and other category, Gagan uncle?


                                                                                                   6
Gagan- Vivek the other group is non intentional contaminants that can come during
production, processing, packaging and storage.
Vasudha- ……..colours and flavours are most used substances in the food items.
Sagar- It is not always manufactures bad intention for which he adds colours and flavour in
these food items.
Medha- Then…….
Sagar- Food colours and flavours are used for providing visual effects and also to meet
consumers demand on quality and price.
Gagan- yes Medha legally eight synthetic colours; sunset yellow, Tartrazine, Panaceau,
Cramoisine, Erythrosine, Brilliant Blue, Fast green and Indigo carmine can be added to a food
items either individually or two three colours blended together.
Sagar- but even concentration of these permitted colours too is fixed, I presume…..
Gagan- Yes, Sagar,…. The maximum permissible level of food colours that can be added
either individually or in blend form is 10 parts per million part pf food items.
Medha- ……….means one microgram per gram of food item.
Gagan- Good and correct calculation Medha but for canned food this limit is double.
Medha- ......means two microgram per gram of food item.
Dadda- But in our village markets who care….. shopkeepers add any amount of cow brand
colour in Imarati, or Jalebi…..
Gagan- but Dadda it is an offence, they can be penalized.
Medha- Did you see today’s news on T.V. Gagan uncle?
Gagan- No, what happened?
Vivek- Consumption of poisonous mustard oil killed 4 people of a family.
Gagan- Oh, though many adulterants are mixed in edible oils but few of these are very
dangerous to human health.
Medha- which one?
Gagan- Mustard oil is most commonly adulterated with a wild plant, Argemone maxicana, a
plant with beautiful yellow flowers and spiny leaves and stem.
Dadda- Gagan lalla we call it “Bhat Kataiya”. Its seeds almost resembles mustard seeds.
Some dishonest persons of our village used to mix these with mustard seeds and sell it in the
town.
Sagar- Dadda when oil is extracted from this mixture, mustard oil is contaminated with
Argimone oil.



                                                                                           7
Gagan- Yes Sagar, this Argimone oil contains two dangerous alkaloid which on consumption,
causes a disease called “Epidemic dropsy”
Medha- Epidemic dropsy, Gagan uncle?
Gagan- yes Medha, in this disease body swells up, affected person has intractable vomiting,
diarrhoea, nausea, fever, redness of the body etcetera.
Vasudha- My God…
Gagan- yes bhabhi in severe cases affected person may die due to heart and lung failure.
Dadda- for few extra bucks a person can create such havoc…. this is unbelievable.
Sagar- I remembered many out breads of epidemic dropsy, in 1998 in delhi, in 2000 in
Gwalior, in 2002 in Kannauj U.P and in 2005 in Lucknow.
Dadda- That’s why we grow mustard in our fields and extract oil from it, pure and safe.
Gagan- Dadda but every one can’t do that.
Dadda- That’s right……
Gagan- People do make so called artificial mustard oil too.
Vasudha- Artificial mustard oil!
Gagan- yes bhabhi they mix butter yellow a dying material to any cheep light pale oil and
produce original mustard yellow colour. To produce mustard oil pungency, they add Allyl
isothiocynate.
Sagar- Horrible!
Gagan- This butter yellow dye interacts with D.N.A, so may be toxic to genes and may
produce, liver tumour and cancers of respiratory tract too.
Medha- I think it is the lowest forn of human morality.
Gagan- No Medha, we human can still be more gruesome. People mix a colour less chemical
used in vanishes, called Tricresyl phosphate to Rapseed oil. This causes paralysis of hands.
Vasudha- your tea is ice cold now Gagan bhaiya…… I think this will also be called
adulterated (Everyone Laugh) I am bringing you a fresh cup of tea
                                                                              (Vasudha exists)
Sagar- There is unending trail of food adulteration. People can mix anything in the food items
which can go unrecognised. They can mix bricks powder in powdered chilli, papaya seeds in
black paper seeds, coloured gram flour in Turmeric powder, charcoal grass seeds in whole
cumin seeds and even white stone powder in powdered common salt, animal dung in
coriander powder…………
Dadda- holy heavens, animal dung in coriander powder!...... and we, the religious people eat
it….. I feel like vomiting………..


                                                                                               8
Vivek- …..but not here at Dadda, not in the room.
                                                                             (Everyone laugh)
Gagan- They mix soap stone or even black soil in Asafoetida or Hing ,……
                                                                             (Vasudha enters)
Vasudha- Gagan bhaiya, here is your tea, steaming hot, fresh and pure…… no added colours
and Flavour (laughs)
Gagan- hope so bhabhi because people do mix used and coloured tea leaves, bangal gram
husk or even rusted iron filings in it.
Vasudha- Gagan bhaiya somebody said that pulses we cook in our Kitchen too, are
adulterated.
Gagan- Bhabhi adulteration has reached in every food items, but Arhar dal is the best known
for dangerous adulteration.
Medha- Dangerous adulteration which one?
Gagan- Medha besides harmful colouring materials which are used to make Arhar dal more
attractive, one more legume seed are mixed in Arhar dal.
Vivek- legume seeds, which one?
Gagan- There is a wild plant, called “Khesari” or “Lathyrus”. Its seeds resemble Arhar dal
or it’s easily mixed with Bengal gram fliour or “Besan”
Vivek- Gagan uncle, is it deleterious to human health?
Gagan- Yes Vivek……. very much…… it’s continued consumption in appreciable quantities
for a period of 2-3 months, causes progressive paralysis of legs called “Lathyrism”.
Sagar- This disease is more prevalent in, Ethiopia, Bangladesh, Afghanistan and India.
Vivek- Gagan uncle is there non intentional adulteration of food items… as you said?
Gagan- yes Vivek fungal, metal or aromatic Hydrocarbon contamination are striking
examples of unintentional contamination of food items.
Medha- Fungus! How they can contaminate food items?
Dadda- Fungus can affect food grains at any stage of harvest, and ruins them totally.
Sagar- Tropical condition of India, poor harvest and storing practices, irregular temperature,
unusual rains and floods, increase fungal contamination of food grains and food items.
Gagan- Besides ruining food grains, these fungi also produce toxic substances which can
produce liver and other cancers and kidney failure .
Medha- Gagan uncle, how these metals contaminate the food items, that too unintentionally?




                                                                                            9
Gagan- Through industrialization and use of fertilizer or pesticides many metal like iron,
copper, cadmium, zinc, manganese cobalt, molybdenum, chromium, lead, mercury Arsenic
etcetera are introduce in our environment.
Sagar- …… and from here these metals reach in our food grains.
Gagan- Among these lead, Mercury and Arsenic are great cause of concern.
Vivek- Why?
Gagan- Lead affects developing brains of the children and to foetus in pregnant ladies,
dangerously.
Sagar- I have learnt that there is a department for prevention of food adulteration.
Gagan- Right Gagan, this comes under preview of “Food and drug administration
department” and there is an act for it, called “Prevention of food adulteration act 1954”
Vivek- Act…… What do you mean?
Gagan- Vivek, for you it means a well organized set of laws about prohibiting, preventing
and penalizing food adulteration.
Vasudha- Some time inspectors raid these shops, milk vendors, sweet shops….. so it is by
this department?
Gagan- Through this is a full flagged department but common people identify this with these
inspectors, the persons who take the sample of probable adulterated food item
Vivek- Sample, what do you mean Gagan uncle?
Gagan- It inspector gets information that some shopkeeper is selling suspected adulterated
food item, he visits his shop and purchases prescribed quantity of food item from the
shopkeeper after fully explaining the intention behind this purchases.
Vivek- So food inspector too purchases the food item?
Gagan- yes Vivek that too with receipt.
Medha- Gagan uncle you said prescribed quantity. How much amount of food article is taken
as sample?
Gagan- It depends on food item, three packs of food items or 200-250 gram of loose food
item or 250ml if food item is liquid or semisolid.
Vivek- Then……
Gagan- loose items are divided in three equal parts and are packed is non reacting, insect and
mice free packing bottles, usually of glass and then label these by marking identification
number, date of collection, place of collection and name of the food product. These bottles are
sealed and signed.
Sagar- Then he sends these samples for analysis.


                                                                                            10
Gagan- No Sagar, he send one sample to “Public analyst laboratory” and rest are sent to
“Local health authorities”.
Vivek- Public analysis labs…… never heard of it.
Gagan- These labs are situated in metros, usually in capital of state.
Dadda- Gagan lalla, suppose if food item is found adulterated?
Gagan- Dadda then a case is filed against the seller in the court after informing the seller, so
if he wants, he can obtain one of the sample from local health authorities and get it checked
from “Central food laboratory”.
Vasudha- and if offence is proved?
Gagan- If adulterant is not injurious to health; the penalty is minimum imprisonment of six
months that may extend up to three years and minimum fine of 1000 rupees.
Dadda- Gagan lalla if adulterant is injurious to health…….?
Gagan- then Dadda, penalty is minimum imprisonment of three years that may extend up to
life imprisonment and minimum fine of 5000 rupees.
Dadda (excited) - good!
Vivek- Suppose if by force or any influence shopkeeper doesn’t let the inspector take the
sample, then?
Gagan- ……..even then penalty is minimum imprisonment of six months that may extend
upto three years and minimum five of 100 hundred rupees.
Vasudha- Gagan bhaiya, we, the house wives do all purchasing of food items and if I suspect
that a food item is a adulterated then what should I do?
Gagan- Simple alternative is that you lodge your complaint or give this information on a toll
free number 1800 180 5533.
Vasudha- what are the other alternatives?
Gagan- Vasudha Bhabhi, you can also inform the food inspector in writing and he will take
the action, alternatively you can also take the sample of adulterated food item after informing
the seller and get it analyses in public analysis laboratory after depositing prescribed fee.
Medha- fee…?
Gagan- yes, it is just to avoid its misuse. However if the sample is found adulterated, fee shall
be refunded. But you will have to appear in court as evidence. The department will manage
rest of the proceedings.
Vasudha- That is a catch point.
Gagan- Catch point….. bhabhi if we, the public, will not come up for the help in penalizing
these culprits, then a radical change is impossible.


                                                                                                11
Vivek- Gagan uncle I wish that there should be some easy methods so we ourselves can check
the adulterant in food items.
Gagan- Vivek…. there are methods by which you can find out adulterants in food, in your
school’s chemistry lab. Medha, I am giving a presentation in your lab tomorrow.
Medha- Really?
Gagan- Yes.
Medha- Then we both will meet you there.
(Music to indicate change of scene………………………………………………………………fades out)


                                            Scene-2
Male anchor- So friends have you listened that no food item is free from these adulterants?
Female anchor- It is a good idea, if we can analyse many of these food adulterant with the
chemicals available in our schools or college chemistry lab.
Male anchor- ………but with prior permission of your chemistry teacher……….
Female anchor- ……..and in his or her presence…..
Male anchor- …… to avoid any chance of accident.
Female anchor- …………but you need to learn these tests first.
Male anchor- So come with us to the chemistry lab of Medha’s school.

(Music to indicate opening of the scene…………………………………………………………fades out)
Place: Chemistry lab in Medha’s school
(Students are gathered here to watch the presentation. Give appropriate sound effect of crowd
noise. Gagan and Medha along with their colleagues are also present. Gradually crowd noise
fades out and voice of Gagan become apparent)
Gagan- Hi, I am Gagan sharma, a senior scientist in local Public analyst laboratory. I have
come here to show some very simple experiments by which you can detect some common
adulterants in adulterated food items. Do you know what are the adulterants ?
Many students (simultaneously) - yes sir.
Gagan- ….. and I have also invited one adulterer uncle to help me…
Many students (in whisper) - adulterer uncle…….?




                                                                                              12
Gagan (Laughs)- No…..No….. don’t get confused…..he is my follow scientist, who will
provide you food articles adulterated by him for this show, so that we learn, how to detect
these adulterants. Are you ready?
Many students (simultaneously)- yes sir.
Gagan- So your adulterer uncle will sit in the next room. You will procure adulterated food
items from him and I will check the adulteration here.

                                             Scene-4
(Music to indicate opening of the scene…………………………………………………………fades out)
Place- chemistry lab of Medha’s School.
                   (In all these experiments give appropriate sound effects as per requirement)
Gagan- So first let me tell you what chemicals and gadgets, I have procured from your
chemistry lab…. this liquid ammonia, concentrated hydrochloric acid, concentrated nitric acid,
potassium hydroxide solution, 20 percent common salt solution, one percent iodine solution
and this water bath, test tubes, sprit lamp, water, hand lens, rubber gloves, and these are
Turmeric indicator paper and Metanil yellow indicator paper.
One student- Which paper?
Gagan- Turmeric indicator paper; for this dissolve one gram of turmeric powder in four
millilitre of ethyl alcohol leave this mixture for some time then filter it. Dip some filter paper
strips in this solution and let these dry. Your turmeric indicator paper is ready.
Medha- and Metanil yellow indicator paper?
Gagan- Metanil yellow indicator paper can be prepared by dipping a filter paper strip in one
percent solution of Metanil yellow in water. Ok. Medha, what you have in your hands.
Medha- Two sample of milk…
Gagan- ok, Medha, put some iodine solution in it.
Medha- ok. Oh it turned blue!


                                                                                               13
Gagan- ……..because this milk sample is adulterated by arrowroot or some other starchy
material which turns blue with iodine solution…. now next milk sample Medha……
Medha- here it is…..
Gagan- Put a pinch of Arhar Dal flour in it and mixes it well ok…. now dip turmeric
indicator paper into it.
Medha- it turned red….
Gagan- Now I am putting few drops of liquid ammonia over this paper.
Medha- Vow, it turned green now…. What does it mean?
Gagan- It means that this milk sample is adulterated with urea.
Medha- Oho……
Gagan- Vivek, What do you have….. Khoya…. ok add some water in it, mix it and boil…..
Vivek- ok……. boiled……
Gagan- Now, I am mixing few drops of iodine solution in it….
Vivek- oops….. it turned blue…..
Gagan- …… Vivek, because your Khoya is adulterated with minced potatoes which contains
lot of starch and this starch turns iodine solution blue.
Medha- ….. this way we can test mixed potato in cheese, butter and curd also.
Gagan- of course Medha.
One student- can we detect water adulteration in the milk?
Gagan- yes, put a drop of milk on polished slanting surface. Pure milk will flow slowly,
leaving a trail behind, whereas dilute milk will flow immediately and without trailing.
One Student- Sir this ghee……
Gagan- Frequently people mix Vanaspati ghee, some flavour and colour in the ghee… (to the
student) melt your ghee sample in this test tube….. add equal amount of concentrated
hydrochloric add and a pinch of sugar…. Now shake……
Student- Then……
Gagan- Keep it for 5 minutes. A crimson colour appears in lowest layer. It indicates vanaspati
adulteration in this ghee.
Medha- and for colouring material mixed in ghee….?
Gagan- Medha add 2ml ghee and 3ml of either, shake and add 1ml. of concentrated
hydrochloric acid. If pink colour appears it indicate colouring matter in ghee.
Vivek- Sir this oil for you….
Gagan- ok, Vivek add equal amount of concentrated nitric acid in it and Shake.
Vivek- A reddish brown colour is appearing in lower acid layer.


                                                                                           14
Gagan- well…. this indicates that oil of Argimone or BhatKataiya is mixed into it.
One student- Sir, test this honey…….
Gagan- ok, take this cotton wick. Dip it into this honey and now burn it over this flame…..
here….. come forward.
Student- it is not burning properly and producing a cracking sound. (give sound effect)
Gagan- …. Because, it is not pure. It is adulterated with sugar solution.
Vivek- Sir takes this sugar sample.
Gagan- Vivek do it yourself. Dissolve it in water and let it stand.
Vivek- Gagan Sir, something is progressively settling down in the test tube’s bottom.
Gagan- Vivek it is chalk powder, mixed in your sugar sample.
One student- Sir this chilli powder for you.
Gagan- This may contain colouring material and brick powder.
Medha- Why brick powder?
Medha- Rub it on this glass surface with your thumb pulp……. feeling grittiness….. this is
because of brick powder or coloured sand mixed in this sample.
Medha- Sir, I have dissolved it in this test tube in water and the solution is coloured.
Gagan- yes this because some colour is added into it.
One student- Sir adulterer uncle has given me these tae leaves…….
Gagan- Sprinkle these tae leaves on a wet filter paper… ok….. now remove these tae leaves.
Student-Sir these Tae leaves have stained this wet filter paper……
Gagan- ………..because these leaves are not original, these are used tae leaves stained with
coal tar dye.
Medha- Gagan sir, this is turmeric powder, how can I test it?
Gagan- …….dissolve this powder in water and add few drops of concentrated hydrochloric
acid. If pink colour appears which disappears on dilution with water, it is pure turmeric
powder.
Medha- if on dilution this colour persists?
Gagan- …… Turmeric powder is adulterated with Metanil ye1low dye.
One student- This sample sir….
Gagan- Sorry little master….. I have to go back…..
Student- But sir………
Gagan- Many such testing methods you may learn from Vigyan Prasar New Delhi. Write a
letter to them or log on their Website http://vidyanprasar.gov.in

                                                Scene-5
Male Anchor- So it is quite easy to detect food adulteration.
Female Anchor- ………these adulterants harm our health in more than one ways.
Male Anchor- Brick powder mixed in chilli powder, coal tar dye in tea leaves, chalk powder,
mixed in sugar, starch mixed in milk, ghee, butter etcetera, malachite green of coloured peas,
urea mixed in milk; causes tummy ache and many tummy diseases.
Female Anchor- colorants such as Metanil yellow, Malachite green, prohibited colours of
sweets, drinks, ice-Cream etcetera can produce cancer in various organs.
Female Anchor- you can register your complaint of food adulteration on national toll free
number. This number is 1800 180 5533, I repeat 1800 180 5533.
Male Anchor- This toll free number, 1800 180 5533, you should use honestly and cautiously.
Female Anchor- Do not misuses it to settle your personal grievances with some shopkeeper.
Male Anchor- How we can avoid these adulterated food items?
Female Anchor- Used food items of reputed companies.
Male Anchor- Avoid buying cooked foods.
Female Anchor- Go natural….. avoid added colours and flavours in the food items.
Male Anchor- Do not purchase loose powdered spice, either purchase packed spices of
reputed companies.
Female Anchor- It’s better if you purchase whole spices and make its powder in your mixy at
home.
Both- Avoid adulterated food…. Live healthy….. live long…..
