2.4 protein isolate
product made through removing or partially removing non-protein components (such as water, fat and carbohydrate) from vegetables through processes such as extraction, concentration, isolation and purification
2.5 vegetable hydrolyzed protein
product with protein as main component, which is made by moderate hydrolysis of vegetable protein
