In order to reduce the contamination of the seed kernel after breaking the nut, break the kernel before sanitation, clean the place.
They can not be broken directly on the ground. After the nuts are broken, they should be put into clean baskets or piled on the field with a mat or plastic sheet. When cleaning the kernels, you must wear clean gloves, and the kernels should be placed in clean containers before sorting and packaging.
