Hydrolyzed soy protein

Hydrolyzed soy protein (CAS 68607-88-5), also marketed as soybean peptones, is produced by breaking down soy protein into shorter peptide chains and free amino acids. It functions as a humectant, emulsifier, and film-forming agent across food, cosmetics, and animal nutrition applications.

In food manufacturing, it acts as a flavor enhancer and savory base in soups, sauces, seasonings, and processed meat products. It contributes umami depth without added MSG, making it a versatile ingredient for clean-label savory formulations.

Cosmetic formulators incorporate it into hair conditioners, shampoos, and skin serums. Its peptide fractions bind moisture to the hair shaft and support surface hydration in leave-on products, enhancing the overall texture and feel of personal care items.

In animal feed and aquaculture diets, it serves as a highly digestible protein source that improves palatability. It supports growth performance in young or sensitive animals by providing essential amino acids in an easily absorbed format.

The material is also used in fermentation media and microbiological culture applications as a nitrogen source for microbial growth. This makes it essential for laboratory settings and industrial biotechnology processes requiring consistent nutrient profiles.

Hydrolyzed soy protein is supplied as a spray-dried powder or liquid concentrate, with powder being the dominant commercial form. Food-grade and feed-grade specifications are standard for most industrial and manufacturing requirements.

Cosmetic-grade material is available with defined molecular weight fractions targeting specific skin or hair penetration profiles. Degree of hydrolysis varies by supplier and end-use requirement, making specification alignment a key step in sourcing.
