Soy Protein is a food-grade versatile plant-protein ingredient derived from defatted soybean meal, available as flour (50%), concentrate (70%) or isolate (90%+).We supply bulk Soy Protein sourced from leading China manufacturers, available in powder form for food and beverage manufacturers worldwide. Our Soy Protein is widely used in meat extension, plant-based dairy alternatives, bakery, shakes and paediatric nutrition.
Soy Protein is manufactured from defatted soy flakes via aqueous extraction (SPI), alcohol/acid washing (SPC) or simple milling (soy flour).
It delivers a complete amino acid profile (PDCAAS ≈1.0), versatile functionality (emulsification, gelation, water-binding, foaming), and a long history of safe use in meat extension, dairy analogues, bakery, nutrition and infant formula.
