Gelatin E411 is a versatile, protein-based hydrocolloid derived from collagen, widely used as a gelling agent, thickener, and stabilizer in food, pharmaceutical, and industrial applications. It appears as a pale yellow to colorless powder, granule, or sheet, with a neutral odor and taste. Gelatin E411 is highly soluble in hot water (above 40°C), forming a viscous, transparent gel upon cooling, and is insoluble in cold water and most organic solvents. Its bloom strength, a measure of gel firmness, typically ranges from 50 to 300, depending on the grade.
With a molecular weight of 20,000–100,000 Da, Gelatin is thermally reversible, melting at 30–35°C and re-gelling upon cooling, making it ideal for dynamic food formulations. It is stable under neutral pH conditions but degrades in highly acidic or alkaline environments. Gelatin’s unique ability to form thermoreversible gels, combined with its film-forming and emulsifying properties, makes it a critical ingredient in confectionery, dairy, pharmaceuticals, and cosmetics.
