Basic information
Product Name: Soybean extract
Appearance: Brown to yellow powder or granular
Standard Packing: 25kg/drum
Solubility: Dissolve in water and ethanol.
Source & Extraction Process:
1. Raw Material: Soybean seeds (GMO/non-GMO)
2. Key Components:
● Proteins (40%-50%): Soy protein isolate (SPI), peptides
● Isoflavones (0.1%-0.3%): Genistein, daidzein
● Lipids (20%): Lecithin, unsaturated fatty acids (linoleic acid)
3. Extraction Methods:
● Alcohol Extraction: For isoflavones (purity up to 40%-80%)
● Water Extraction: Produces soy protein (purity ≥90%)
● Supercritical CO₂ Extraction: Yields solvent-free lecithin
Standard: CP2020, JP, Customer Made
