1. What is Silk Sericin?

Silk Sericin is a natural, water-soluble glycoprotein derived from the silkworm cocoon (Bombyx mori). It acts as a natural adhesive that binds the fibroin fibers (the main structural protein of silk) together. Comprising 18 kinds of amino acids (including 8 essential ones for humans), it is rich in hydrophilic amino acids like serine, which gives it exceptional moisture-binding properties.

Unlike the more commonly known Silk Fibroin (which is insoluble and structural), Sericin powder is prized for its solubility, antioxidant activity, and biological functions.

Functional Properties of Silk Sericin Powder

Antioxidant activity – Helps scavenge free radicals (in vitro studies)

Moisture retention – Can improve texture and water-binding capacity in food systems

Metal chelating – May bind trace metal ions

Hypoallergenic potential – Considered mild; however, individuals with silk protein sensitivity should exercise caution

Silk Sericin Powder Potential Applications in Food

Nutritional supplements – Capsules, tablets, or powder sticks

Protein enrichment – Smoothies, protein shakes, health bars

Functional beverages – Clear protein-fortified drinks

Bakery & confectionery – As a humectant or film-forming agent

Edible coatings – For fruits or nutraceuticals (requires further process validation)
