STORY OF NUT

Native to the tropical regions of Brazil, cashew tree (Anacardium occidentale), produces a long, fleshy stalk, called a cashew apple. At the end of this stalk grows the kidney-shaped cashew nut that many know and love. Sprouting like a tail from the bottom of an oddly-shaped fruit, the cashew, in its natural state, is both very weird-looking and very poisonous. The experienced persons detach the nuts from cashew apple.

Cashew Nut Processing

The process of manufacture is well-established. The processing begins with the drying of Cashew nuts. Sun drying helps the best for the purpose. After drying the nuts are stored in gunny bags. Steam boilers are used for boiling stored raw cashews. There are manufacturers of small scale boilers available for boiling of cashew nut in most of the cashew processing areas. The boiling helps in softening of cashew shell. It becomes easy to remove nut inside cashew seed after boiling. Now, removal of shells of steamed cashew nut by skilled labor, making use of cashew cutting hand operated equipment. The cashew shell involves usage in extraction of cashew nut shell liquid (CNSL), which is an important by-product of cashew industry.

Cabinet driers help in the drying of Cashew kernels. The next step is the removal of outer reddish skin known as testa to obtain cashew nut after drying.The next process involves grading of Cashew nuts. There are 27 specific grades of cashew nut kernels obtained from peeling. Selection of kernels according to size, shape color, and count. After grading the next step is packaging. Vacuum packaging is done.The final process prevents the product deterioration and extends the storage/shelf life of the kernel up to 5 years if the pouch is not punctured.
