Starting a Cashew Nut Processing Business
Cashew (Anacardium occidentale) is widely grown in the tropics because of its
cashew nuts and apples. The cashew apple can be eaten raw or used in the
production of jam, chutney, pickles or various beverages like juice and wine.
The primary product of cashew nut is the kernel which is used extensively in the
confectionery and baking trade. The cashew nut kernels are popular dessert,
generally eaten roasted and salted.
The main goal of processing is to remove the valuable cashew kernel from the shell
with minimal damage. Difficulties in shelling cashew nuts are due to irregular shape
of the nut, the tough leathery outer shell and the cashew nut shell liquid.
Starting the Business
In cashew processing, micro-entrepreneurs can start with two shellers and a
charcoal-fired oven to produce plain roasted cashew kernel. This combination of
cashew postharvest facilities can be operated at a minimum input level of 4,000 kg
cashew nuts. This will require a working capital of P50.000 worth of cashew nuts and
processing facilities worth P18,000 including the weighing scale, kalukati, impulse
sealer and others. This investment can generate a net income of P125,000 for a
period of only two months with a Return on Investment (ROI) of 68.64% and a
payback period of 1.46 years.
The various cashew nut processing steps differ in accordance with the scale of
operation. In some cases, all steps of the processing are manually carried out by
small-scale processors. In commercial processing, various pieces of equipment are
used. The cashew nut processing operations consist of cleaning, roasting, shelling,
separation, drying, peeling, grading and packing.
Cashew Nut Processing
1. Clean cashew nuts of foreign matters like sand, stones and dried apple.
2. Dry the shelled kernel to facilitate removal of testa. Drying protects the kernel
from pests and fungi attack
3. Shell big cashew nuts with the BPRE cashew nut sheller. Split the other nuts
using kalukati (an indigenous tool).
4. Separate the shelled pieces from the kernels. The unshelled nuts are returned
to the shelling operation.
5. Peel the testa manually by gently rubbing with fingers. It is important that the
kernels are neither cut nor damaged during the peeling process.
6. Roast the cashew nuts to release the cashew nut shell liquid and make the
shell brittle. This will facilitate the extraction of the kernel when breaking the
7. Grade the kernels for quality control. Shelled, dried and peeled kernels are
graded for export according to size and condition.
8. Pack into appropriate containers the cashew kernels.
Whole kernels command higher price than do broken pieces.
To produce whole,Cashew Nut Shell Liquid (CNSL)-free cashew kernels, BPRE
adapted from Khon Khaen University of Thailand, a low cost, manually-operated
shelter for small-scale processors.
The BPRE whole cashew kernel sheller produces more whole kernels. Moreover, the
sheller is locally manufactured, very affordable and easy to operate.
The following are the specifications of the BPRE whole cashew kernel sheller:
Height : 25 cm
Weight : 2.35 kg
Base dimension : 12 cm X 12 cm
Shelling capacity : 30 kg raw nuts/ 8 hr operation
Shelling efficiency :
o 53 % whole kernel
o 47 % split kernel

This recipe for cashew brittle is perfect for Christmas.
2 cups granulated sugar
1 cup light corn syrup
1/2 cup water
1 cup butter
3 cups cashews
1 teaspoon baking soda
In a large saucepan, combine sugar, corn syrup, and water. Cook over medium heat,
stirring, until sugar dissolves. Bring to a boil; blend in butter. Begin to stir frequently
when syrup reaches the thread stage, about 230°F.
When temperature is 280°F, or soft-crack stage, add cashews. Stir constantly until
hard-crack stage, at 300°F, is reached. Remove from heat and quickly stir in baking
soda. Mix well. Pour onto two buttered baking sheets or jelly roll-size baking pans.
As the candy cools, stretch it out thinner by lifting and pulling at edges with forks.
Loosen from the pans as soon as possible and turn over. Break hardened candy up
and store in an airtight container.
