 |
|
| |
Cashews are graded on how white they are and how broken the kernel is. There are four color grades, four styles of break on the kernel and six sizes (or maximum number of kernels per pound) |
|
| |
|
|
| |
Classification Method 1 - Classified according to grades / with or without basing on number of kernel per kilogram. |
|
| |
|
|
| |
Cashew kernels have been classified according to 6 quality levels |
|
| |
|
|
| |
Explanation of cashew grade terminology: The alphabets at the front represent a word descriptive of the form of cashew – W for whole, B for Broken, S for Split etc. The numbers that follow the alphabets (where present) usually represent the number of kernels per pound. Hence, to give an example, W 210 implies that it is a whole cashew kernel which gives 210 kernels per pound. |

Classification Method 2 – Based on whether the cashew kernel is whole or broken |
|
| |
|
|
| |
Plain Natural Wholes - Cashew is graded in three categories based on colour. White Wholes (“W” appearance – white, pale ivory), Scorched Wholes (“SW” – slightly reddish) and Scorched Wholes Seconds (“SSW” – discolored); W and SW Wholes are graded according to size, i.e. number of nuts per Pound; Super Premium – W 150; Premium – W 210; Regular – W 450; Economy – SW 450 |
|
| |
|
|
| |
Natural Halves - Cashew Kernels broken evenly into 2 parts are less expensive than wholes. They are used in economy packs and also for candy bars, sweets and pastry. Splits are crisper than wholes and sometimes preferred for that reason. The different varieties are: Fancy Splits (FS): White halves split lengthwise; Fancy Bults (FB): White halves broken crosswise; Scorched Splits; Scorched Bults |
|
| |
|
|
| |
Natural Broken’s - Natural Cashew pieces are used in economy packs and also in confectionery, pastry, ice creams & cooking; Large White Pieces (LWP); Scorched Pieces (SP); Scorched Pieces Seconds (SPS) |

Technical Requirements for Cashew Kernels |
|
| |
The following are some of the typical technical requirements of cashew kernels that are traded in the various parts of the world: |
|
| |
- The kernels should be dry and should have the characteristic shape. While depending on the grade they can be either scorched or unscorched, wholes or broken, they should be free from oil (CNSL) and the think outer skin.
- Cashew kernels should be completely free from living insects, moulds, from rodent contamination and insect damage
- Cashew kernels should have natural smell, and should be free of rancid or any other unnatural smell.
- Moisture content: The cashew kernels should have moisture content not greater than 5% by weight.
|
|
| |
Cashew Kernel Preservation |
|
| |
Cashew kernels should be preserved in a dry clean place, far from heat resource. The storage of preservation should be closed, dry clean, free from foreign smell, no insect, rodents. |
|
| |
|
|
| |
Cashew Kernel Transportation |
|
| |
Cashew kernels should be transported by dry, clean, closed transport facilities that free of foreign smell. The loading operations should be done gently, with care. |
|
| |
|
|
| |
Cashew Kernel Standards |
|
| |
Cashew kernel standards have been laid down by the following organizations : |
|
| |
- AFI (Association of Food Industries of New York)
- TCVN 4850 1998 - Vietnam Cashew Nuts Kernel and Technical Request
- CENTA
- Grade Specification for Indian cashew Nuts kernel
