低值可口革囊星虫体壁胶原蛋白特性研究

AbstractUsing Phascolosoma esculentas in Vietnam as raw materials,the collagen was extractedfrom body wall by acid method,and the physical and chemical properties of the extractedcollagen were studied.Collagen was analyzed by ultraviolet full wavelength scanning (UV),SDS-PAGE gel electrophoresis,amino acid analysis,viscosity and denaturation temperaturecharacteristic determination,gel strength and moisture retention.The results showed that theultraviolet scanning wavelength of ASC of Phanerochaete vietnamese had the maximumabsorption peak at 230nm.SDS-PAGE electrophoresis results showed that ASC ofPhanerochaete vietnamese contained B,al and a2 chains,belonging to type I collagen.Thecontents of glycine,glutamic acid and proline in ASC of Phanerochaete vietnamese arerelatively high.ASC denaturation temperature of Phanerochaete vietnamese is 33.6C,whichhas good thermal stability.The gel strength was 84.65 N;The moisture retention rate is lowerthan that of glycerol.Key words:Phanerochaete viemnamese;acid method;collagen;Physical and chemicalcharacteristics
