3.6 Water-soluble protein
Protein soluble in water in peanut cakes and meal under certain conditions. 3.7 Water-soluble nitrogen
Nitrogen soluble in water in peanut cakes and meal under certain conditions. 3.8
Nitrogen solubility index (NSI,%)
The percentage of water-soluble nitrogen in total nitrogen, or the percentage of water-soluble protein in crude protein. Hydrochloric acid insoluble ash (sand content)
Substances in peanut cakes and ash that are insoluble in 10% hydrochloric acid. 3.10 Impurities
Material other than peanut cakes and cakes and meal without edible value. Classification
4.1 Peanut cakes.
4.2 Peanut meal.
Highly denatured peanut meal.
Lowly denatured peanut meal.
