Preparation and Physical Stability of Nile Tilapia Fish Skin Collagen Creams

Abstract

Objective: To prepare and test physical stability of the Nile Tilapiafish skin collagen cream. Methods: The research was divided into 2parts as formulation and physical stability tests of skin care product.The physical stability tests included 6-cycles freeze thaw, andtemperature stability at 25, 35 and 55 C for 3 months, then thestability evaluation were performed as chemical (pH), and physicalstability (texture, color, viscosity) as well as the separation aftercentrifugation, compared to a freshly prepared product. Results:Hereby, we found that the cream containing 1% Nile tilapia fish skincollagen was characterized as white-yellowish fine-texture creamwith a weak acid pH (pH5) and a viscosity appropriate for skin. Itprovided a good physical and chemical stability after 5-cycles freezethaw.Its shelf life appeared to be at least 90 days at 25 C.Conclusion: Cream containing 1% Nile tilapia fish skin collagen hadan acceptable physical stability profile.Keywords: collagen, Nile Tilapia fish skin, cream, stability, freezethaw
