         The total fermentable sugars in bananas, plantains and pineapples depend on the
         extent of ripeness. The sugar level of ripe pineapple was found to be less than
         12% which was necessary for better fermentation. Both the stain and pulp of
         bananas and plantains contains appreciable fermentable sugars and these can be
         used for alcohol production. Alcohols produced are free of contaminants and
         higher alcohols.

         . Over 30% of harvested fruits were lost on the farms and markets due to these
         two prominent problems which was coupled with inefficient and poorly
         developed transportation net-works system.
         Price instability as usual, was also found to be another problem. Price from the
         rural markets ranges between N50.00 and N600.00 depending on the freshness
         and taste of the fruits and size, while the selling price range in the urban markets
         was found to be between N120.00 and above N750.00, leaving a profit margin of
         N70.00toN150.00per basket. Attempt was also made to get average shelf life of
         this African star apple. Five (5) days period was indicated to be optional shelf life
         of C. albidum.

          A survey of the rot diseases affecting sweet orange citrus sinensis Valencia
          variety was carriage old between January and October 1984. Two major types of
          rot diseases were recognised, soft and dry rots. Soft rot caused by Botryodiplodia
          theobromae ranked first with an incidence of 55..72% followed by Penicillium rot
          with 37.24% the incidence of dry rots was low 13.76 and 19.02% respectively.
          Observations showed that insect bites and injuries sustained during harvesting and
          transporting enhanced fast deterioration. Also the habit whereby traders heaped
          the oranges on the floor facilitated the spread of the rot diseases as water from
          diseased fruits dripped into underlying fruits.

          Nigerian Journal Of Microbiology Vol.11. Pp. 36-37.

         Samples of dry „tatase‟ pepper stored for sale in four major markets in Ibadan,
         Oyo State, Nigeria between November 1988 and February 1989 were analysed for
         the incidence of the different types of micro-organisms present in them and the
         aflatoxin content. The study showed that there was a low incidence of micro-
         organisms due to the prevailing dry season with the staphylococcal species, being
         more numerous (0.33x102-2.0x104) than the coliforms (7.63x102-7.33x103) and
         yeasts and moulds (1.89x102-3.0x102). No salmonella and shigella species were
         isolated. Similarly the aflatoxin level was below 5ug/kg.

         It was concluded that sweet orange can be stored well so as to maintain stable
         prices throughout the year by hand. Picking them from trees at harvest and
         packing them with foil or perforated polyethylene bags to preserve them and then
         store under a temperature range of 12-15oC in incubators. Storage method,
         influenced net benefits as the open shelf storage methods with fruits obtained by
         shaking the to bare ground with no wrapping (control) had the lowest net benefits
         as compared with storage of wrapped fruits in either evaporative coolant structure
         or the incubator greater returns were obtained from fruits that were handpicked
         wrapped in foil and stored in the incubator for both early and late season crops,
         these observations indicated that the storage, packaging and harvesting methods
         used influence the storage of citrus.

         The study evaluated the acceptability and physical characteristics of „Ukwa”
         cakes. The high cost of food, (especially protein) results in mal-nutrition, ill-
         health and death of both children and adults. There is therefore the need to use
         „ukwa‟ an unpopular local plant, rich in protein to enrich wheat flour cakes.
         „Ukwa‟ seeds without husks were bought, picked and washed twice. They were
         then properly sun-dried and milled into flour. Samples of cakes were made from
         100% wheat flour (control), 50% wheat 150% ‘ukwa’ flour and 100% ‘ukwa‟
         flour with labels of X3 Y2 and Z3, respectively. Three experiments were carried
         out and all the products were evaluated for colour, texture, flavour and general

         leafy vegetables Telfairia occidentalis and Pterocarpus soyauxii, at ambient (30-
         35oC) and low temperature (10oC) was investigated in South-easthern Nigeria.
         The effect of seal – packaging the vegetables in polyethylene and paper bags on
         quality decline of the leafy vegetables was also monitored. Unsealed leaves of T
         occidentalis and P. soyauxii rapidly lost water during storage at either ambient or
         low temperature. There were decreases in the chlorophyll, protein and ascorbic
         acid contents in the stressed leaves. Packaging of the leaves in polyethylene bags
         salleviated these losses. Sealing of the leaves in polyethylene bags also alleviated
         water stress.

         uniformity and remained fresh much longer than those stored under ambient
         conditions. Decay was however, more prevalent under the ECS most of the decay
         was caused by Cladosporium herbarium, Fusarium, moniliforme and Penicillium
         citrinum. Despite this, however, the ECS holds considerable promise for the
         preservation of tomatoes.

         Plantain flour produced after drying green plantain pulp at temperatures between
         50oC and 65oC was used for the production of plantain biscuits. Baking trials
         were carried out using 100% plantain flour as well as 70% plantain flour in
         combination with 30% plantain pulp (solids) in order to develop suitable recipes
         for the pilot-scale production of plantain biscuits. Three different recipes were
         developed and good quality flow-type biscuits produced using rotary moulder.
         The plantain biscuits produced were acceptable to the majority of Nigerian
         consumers, who expressed their willingness to buy them if sold in the market.
         There was distinct plantain flavour which might be an advantage for those who
         grow and eat plantain. The economic impact of the use of plantain (flour/pulp) in
         the manufacture of biscuit lies in the substitution of some of the wheat that are
         imported with a locally grow crop

         The physical properties of the dough made from a composite flour of strong
         wheat flour (Leviathan) and plantain flour were determined using Brabender
         Extensograph, Fairnograph and Amylograph. The water absorption of the blends
         decreased slightly. There was a marked reduction in peak development time and
         stability with dilution of the strong wheat flour with the plantain flour. The dough
         was more plastic as the level of dilution increased and the maximum viscosity of
         the slurry increased with increases in the proportion of plantain flour in the
         mixture. As the dough matured it became shorter and displayed greater visco-
         elastic properties Examining the ratio figures obtained in the extensograph test, it
         can be assumed that suitable dough with acceptable visco-elastic properties would
                                          22


         be produced from a 10% dilution for a short to medium length fermentation

         until the overripe stage, while the alcohol insoluble solids decreased. The force
         required to puncture the skin of the fruit at the turning stage when both green and
         yellow colours appeared on the fruit and ripe stage was 10.3kg and 7.5kg
         respectively. A force limit of about 9kg and 8kg could be set for puncture and
         rupture processes respectively below which drying the fruits would pose some

         Understanding the drying behaviour of plantain cubes over a range of
         temperature, air velocity and cube size was considered necessary for the selection
         or design of suitable dryer for the drying of plantain. Plantain cubes 5mm, 10mm
         and 15mm were dried as a single cube in air stream and in a single layer on a tray
         at temperature, 40o, 49o and 60oC and at air velocities of 2.4, 2.9 and 3.4m/s.
         Increase in air velocity increased the treat transfer co-efficient and decreased the
         external resistance to mass transfer. Increase in air temperature reduced the
         drying time but care should be taken to avoid case hardening of cases at very high
         temperatures which ultimately result in lower drying rate. The rate of drying was
         faster for single cubes than for a single layer of similar cubes packed in a tray.

         This paper describes the plant trial carried out using a cabinet dryer for the drying
         of plantain. Perforated and non-perforated trays were used for the experiment and
         loadings of single, double and triple layers of 10mm plantain cubes and slices
         respectively were dried at temperatures of 67oC and 77oC. The conclusions were
         that dicing of plantain pulp produced more uniform cubes than slicing and the rate
         of drying was faster for cubes than for slices. The use of perforated trays greatly
         reduced the tray wetness and improved the rate of drying. Drying plantain cubes
         at a temperature above 70oC had not resulted in a faster rate of drying to the affect
         of case hardening on the surface of the cubes.

          characteristics, showed a drastic change after the addition of 20% cassava starch
          and an addition of 5% Oilseed flour to wheat flour. Loaf volume decreased from
          1765cc to 11412cc on addition of 30% cassava starch. Addition of 10% Oilseed
          flour led to a great reduction in loaf volume. Loaf score dropped significantly on
          addition of 10% defaulted Oilseed flours whereas 5% addition of defaulted
          Oilseed flours gave loaf score of over 90%.

          nudiflorum and myrianthus arboreus were analysed for food constituents minerals
          and oxalate. All the vegetables are relatively high in protein and could be used as
          protein supplements. The leaves are rich in minerals compared with those of
          imported vegetables such as spinarch and lettuce. They are extremely high in
          aluminium and manganese, probably due to the acid granite soil in which they
          were grown. Heinsia and Gynuna contain a high amount of oxalate. In order to
          improve the quality of the vegetables it is suggested that attention be concentrated
          on the breeding of strains low in oxalate.

          respect to the degree of post harvest maturity for reducing moisture level of
          plantain slices. The firm ripe stage of maturity was found most appropriate since
          it ensures about 71% removal of initial moisture as against 68% and 58% for the
          “unripe” and “over ripe” stages, for plantain slices 3.5mm thick (immensed in 61o
          Brix sugar solution at 27oC to 23hours. Furthermore, the incidence of leaching of
          nutrients in osmotic dehydration was examined. Dehydration is accompanied by
          leaching of water reducing sugars as well as absorption of sugar from the
          dehydration medium by plantain slices immersed in sugar solution. The extent of
          nutrient leaching, dehydration and sugar uptake depend, in a large measure, on the
          thickness of the plantain slices.

         Potential Role Of Out-Of-Season Vegetables.
         Outlook On Agriculture. Vol. 25. No.2.

         In Nigeria, most people still rely on rainfall vegetables for their vegetable needs.
         And for very good reasons: they are relatively easy to grow. However, their
         production as seasonal and has become unreliable because of problems of
         transportation, marketing and storage. Consequently, fresh produce is often
         surplus to marketing requirements, resulting in low prices and huge losses during
         the rainy season in scarcity and high market prices during the off season. It seems
         that rainfall vegetables can no longer continue to meet the demands of the fast-
         growing population, and it is time to examine the role of our of season vegetables
         as well.

             Starter – organisms were used in the production of vinegar from pineapple
             Alcoholic fermentation phase was carried out for 10 days using Saccharomyces
             carlsbergensis. A10% alcoholic content was obtained with a final PH of 4.5.
             Acetification was done using Acetobacter aceti and Acetobacter mesoxydans
             isolated from palmwine. A .cetic singly inoculated produced 3.8% acetic acid
             compared to 4.2% produced using both organisms. Characteristics properties of
             the vinegar such as iodine and oxidation values, total solid and ash contents are
             reported.

         The viscosities of achi and ogbono seed gums were time independent. Ogbono
         seed gum (OSG) was more pseudoplastic than achi seed gum (ASG). The
         psaudoplasticity of the gums was not affected by increasing temperaturs up to
         70oC. Temperature control was more critical for OSG (Ea, 20.2 MJ mol-1) than
         ASG (Ea, 13.9 MJ Mo1-1). The viscosity behaviour of ASG suggests that it may
         be a highly branched polysaccharide. The overrun, viscosity, shape factor and
         meltdown values of ice cream when ASG was added as stabilizer were 95%,
         35cp. 72% and 32%, and 70%, 25cp.65% and 37.7% respectively for ASG. Ice

         The results obtained indicated that, the ripening of plantain can be profitably
         delayed if the fruits are stored in atmospheres containing low oxygen
         concentrations and little or no ethylene gas. Plantain fruits with better physical
         appearance and quality were obtained in storage systems in which the fruits were

          also noticed to have affected by the age of the plantain used. The study on the
          variations of moisture, total sugar and carotene contents revealed an increased
          accumulation of these constituents in agreement with biochemical frist principle
          predictions.

          Journal Of The Science Of Food And Agriculture. Vol.45. No.4. Pp. 333-336.

          The composition of minerals and organic contents of the peels and pulps of unripe
          (green) plantain( Musa paradisciaca L) through five different ripening stages
          were determined. Crude fibre, ash, fat, crude protein and moisture contents were
          higher in the peels than in the pulps wheras carbohydrate and dry matter contents
          were higher in the pulps than in the peels at different stages of ripening.
          Potassium is the most abundant mineral in both samples with estimated values of
          37gkg.l in the green peel and 8.4g kg.1 in the green pulp . Small increases in
          potassium content were found in both samples during ripening. Iron, calcium and
          sodium show similar variations but phosphorus levels decrease as ripening
          progressed. The concentration of copper and magnesium ions remained fairly
          constant. The estimated values for copper were 13mg kg-1 and 10 mg kg-1 for
          the peels and pulps, respectively. However, the magnesium contents in the pulp
          of 41mg kg-1 was constant whereas that of the peel increased as the fruit ripened.
          The low sodium content (350mg kg-1) is an advantage in the treatment or
          prevention of hypokalaemia.
