Molecular Formula: Mixed polypeptide mixture (multiple short-chain amino acid polymers)
Molecular Weight: Mixed molecular weight range 200–1000 Da
Category: Plant-derived hydrolyzed protein raw material, culture medium nitrogen source, cosmetic moisturizing additive, food nutrition fortifier
2. Physical and Chemical Properties
Physical Properties
- Appearance: Pale yellow to off-white fine powder
- Odor: Mild characteristic soybean fragrance, no rancid odor
- Solubility: Fully soluble in cold and hot water; slightly soluble in ethanol; insoluble in oil, ether, aliphatic solvents
- Melting Point: Decomposes above 200 ℃
- Density (predicted): 1.35 g/cm3
- Hygroscopy: Moderately hygroscopic under high humidity
- Aqueous property: Weakly acidic to neutral aqueous solution, stable at pH 4–9
Chemical Properties
- Molecular structure: Mixture of small molecular peptides and free amino acids obtained by enzymatic hydrolysis of soybean protein, rich in glutamine, arginine, serine
- Hydrolysis characteristic: Further hydrolyze into single amino acids under strong acid/alkali heating conditions
- Chelating ability: Amino and carboxyl groups chelate metal ions, can stabilize trace mineral elements
- Thermal stability: Stable below 120 ℃; high-temperature sterilization will not degrade protein nitrogen content
- Photostability: Slightly light-sensitive, long-term strong light storage will deepen color
- Compatibility: Compatible with aqueous buffer, polyols, most cosmetic and food raw materials; incompatible with strong oxidants, concentrated strong acid
