Description
Five authors turn an egg processing byproduct into a skin whitening ingredient in this 2025 study. The byproduct, chalaza, is the ropy part of the egg, rich in sialic acid, and usually discarded by the liquid egg industry.
The team compared three enzymes and settled on a two step hydrolysis that gave high yield and strong antioxidant action. The product held 1.96 percent sialic acid and fourteen distinct sugar chain structures. In cell and zebrafish tests it blocked the key whitening target enzyme and cut melanin output in a dose dependent way, by turning down the genes that drive pigment synthesis. The work gives waste egg material a cosmetic use.
