Application Of Cod Skin Collagen Extraction Method
Abstract
During cod processing, the skin accounts for about one-tenth of the total weight of cod, and it is rich in collagen. Collagen has functions such as supporting body organs and protecting tissues. It is also an important functional protein that makes up the intercellular matrix. Extracting collagen from cod skin not only avoids waste of resources, but also reduces environmental pollution. This article summarizes the common methods for extracting collagen from cod skin in recent years: hot water method, alkali method, salt method and enzymatic method, and analyzes the characteristics of each method. The hot water extraction method destroys the collagen structure and reduces its separator, stabilizing, and assisting transmission functions; alkaline extraction produces a racemic mixture, so this method is rarely used; the products obtained by salt extraction lack stability and are not suitable for large-scale production Production; Enzymatic extraction is low cost, highly efficient, and widely used. Due to its unique triple helical structure, low immunogenicity, low production cost, large-scale production and excellent biodegradability, collagen is widely used in medicine, food, cosmetics and other fields and has great development prospect
