What it is

Hydrolyzed soy protein is a food ingredient made from soybeans. It is produced by breaking down soy protein into smaller protein fragments, called peptides and amino acids, through a process called hydrolysis, which uses water, acids, or enzymes.

Why it's used

It is often used as a flavor enhancer, providing a savory (umami) taste to foods. It also serves as a source of protein and can act as an emulsifier. It is commonly found in soups, sauces, processed meats, seasonings, and snack foods.

Health notes

The U.S. Food and Drug Administration (FDA) considers hydrolyzed soy protein to be Generally Recognized As Safe (GRAS) for use in food. It is generally well-tolerated, but some individuals may experience digestive discomfort. JECFA (the Joint FAO/WHO Expert Committee on Food Additives) has evaluated hydrolyzed proteins and determined that an acceptable daily intake (ADI) "not specified" is appropriate, meaning that based on available data, the total daily intake from food and other sources does not represent a health hazard.

Allergen info

Soy is one of the nine major food allergens identified by the FDA, so products containing hydrolyzed soy protein must declare soy on the label. It does not contain gluten.
