Made from purely plant-based proteins such as soybean and corn by an advanced process, this product contains free amino acids ≥75% and total amino acids ≥80%. Rich in 17 amino acids, it is chloride-free with heavy metals below 0.5 ppm (as Pb). Being derived entirely from plant protein with no animal-origin components, it suits organic farming, green-food raw material cultivation and export markets with restrictions on animal-derived inputs. Water-insoluble matter ≤1.0%, pH (1:250) 4-8, sulphur ≤3.0 g/100g, chloride ≤0.5 g/100g and solubility (25°C) ≥15.0 g/100mL; widely used in water-soluble and foliar fertilisers and as a feed amino acid supplement.
