Walnut Peptide: Derived from natural, pollution-free walnut protein sourced from the Changbai Mountains, it utilizes bioengineering-directed enzymatic cleavage technology to degrade large-molecule proteins into small-molecule peptides with excellent solubility, emulsifying properties, and biological activity. This process enhances the functional characteristics of the protein, boosts its efficacy, and enables its broader application in both conventional and functional foods.
