Product Description

Soy Oligopeptide is refined from high-quality isolated soy protein. Through targeted biological enzymatic hydrolysis, large-molecule soy protein is broken down into a mixture of small oligopeptides, followed by multiple processes including membrane separation ultrafiltration, debittering purification, concentration and spray drying. Most peptide segments of the product have a molecular weight below 1000 Da.

It features excellent cold-water solubility and forms clear aqueous solution. It fully retains various essential and non-essential amino acids contained in soy protein. With stable physical and chemical properties, the raw material is compatible with formulation systems in food, dietary supplement and cosmetic industries. As a plant-derived polypeptide material with optimized flavor, it covers a wide range of applications and can be stably supplied to various formulation manufacturers.

Functions and Effects

◆ Excellent Water Solubility and Dispersion Stability

Featuring a small-molecule oligopeptide structure, it dissolves faster than macromolecular soy protein. It is soluble in cold water with a clear and uniform solution, without precipitation or delamination, suitable for all kinds of water-based formula production.

◆ Rich in Natural Plant Amino Acids

It fully retains various essential and non-essential amino acids from soybeans. The oligopeptide structure blends easily in systems, providing a natural plant-based nutritional foundation for finished products.

◆ Wide Formula Compatibility

With mild and stable physicochemical properties, it tolerates common acid and alkali formula environments. It can be stably compounded with vitamins, carbohydrates, polysaccharides and other active ingredients, fitting multi-category production processes.

◆ Debittered and Flavor-friendly

Adopting professional enzymatic debittering and purification technology, it greatly reduces the inherent bitter taste of soy raw materials, has little impact on finished product flavor, and is ideal for high-end beverages and powder formulas.

Application Fields

◆ Functional Food & Solid Beverages

Widely used in sports nutrition powder, meal replacement powder, functional solid drinks and protein beverage powder, serving as a plant polypeptide additive to optimize product nutritional structure.

◆ Dietary Supplements

Suitable for oral tablets, hard capsules, nutritional powders and other dietary supplements. It is a safe and stable plant protein peptide raw material for long-term formula application.

◆ Personal Care & Skincare Products

It can be added to toners, lotions, serums, body care and other water-based skincare formulas. It enriches the formula system and improves mildness as a plant peptide ingredient.

◆ Special Nutrition & Pet Food

Applied in special functional drinks, fermented foods and pet nutritional supplements, providing high-quality plant-derived polypeptides and amino acid nutrition for special-scenario products.
