Anti-Photoaging Effects of Upcycled Seed Anionic Peptides on Ultraviolet-Radiation-Induced Skin Aging in a Reconstructed Skin Model.

Side streams and byproducts of food are established sources of natural ingredients in cosmetics. In the present study, we obtained upcycled low-molecular-weight anionic peptides (LMAPs) using byproducts of the post-yuzu-juicing process by employing an enzyme derived from sp. For the first time, we isolated anionic peptides less than 500 Da in molecular weight from TANAKA seeds via hydrolysis using this enzyme.
