| Abstract_FL | Objective To develop the optimized conditions of extraction from abalone viscera and provide a reference for the industrialized production on polysaccharides and peptides of abalone viscera. Methods Extraction technological parameters of polysaccharide in abalone were studied with the method of single factor experiment and respond surface methodology. The condition of each factor for extraction polysaccharide form abalone was established through the experiments of different pH, extraction temperature, ratios of material to extraction solvent, enzymatic dosage and extraction time, according to polysaccharide extraction yield and degree of hydrolysis. Results Papain and Trypsin was chosen to hydrolyze abalone viscera and the suitable conditions of enzymatic hydrolysis was as follow:pH 8.0, extraction temperature 40℃, solid-liquid ratio 1:40 and the enzymatic dosage 3000 U/g. Under this selected technological parameter, the extraction yield reached the top of 16.58% at 6 hours and the water-soluble protein hydrolyzing rate, and the degree of hydrolysis and DPPH free radical scavenging activities increased with more enzymatic time. Conclusion It can obtain a higher polysaccharide extraction yield by using Papain and Trypsin, and the enzymatic hydrolysate have a good ability of DPPH free radical scavenging. |
