What are the acceptable declarations for protein hydrolysates that are made of blends of proteins, i.e., the proteins from different sources are hydrolyzed together or individually?
According to FDA rules, for proteins that are blended prior to being hydrolyzed, an appropriate name for the hydrolyzed protein must be sufficiently descriptive of the product and must include all of the various proteins that were used to make the hydrolyzed protein. For example, a hydrolyzed protein made from a blend of corn protein, soy, protein, and wheat gluten would be “hydrolyzed corn, soy, and wheat gluten protein.” If proteins are hydrolyzed individually prior to blending, then the common or usual name of each protein hydrolysate must be indicated, e.g., “hydrolyzed corn protein, hydrolyzed soy protein, and hydrolyzed wheat gluten.
