What is Sericin?

Sericin is a natural, water-soluble protein derived from the silkworm cocoon (Bombyx mori). Unlike fibroin (the structural core of silk fiber), sericin acts as a natural adhesive coating that surrounds and protects the silk filaments. In recent years, food-grade sericin has gained attention as a functional bioactive ingredient for nutraceuticals and functional foods.

Silk sericin powder is a colloidal protein coated on the outer layer of silk. A slight yellow powder, easily soluble in water.
