Food and Machinery

Objective: This study aimed to improve the utilization value of scallop processing by-products, by analyzing the antioxidant activity of its protein hydrolysates. Methods: The processing by-products of Argopecten irradians were used as raw materials, and the proteins were extracted by alkali extraction and acid precipitation, alkali extraction and ammonium sulfate precipitation and low temperature ethanol denaturation precipitation. Then the proteins were analyzed by SDS-PAGE. Pepsin, flavourzyme, dispase and alcalase were used to hydrolyze the protein, and the antioxidant activities of the hydrolysate products were analyzed. The molecular weight distribution, amino acid composition and hydroxyproline content of dispase hydrolysates …

Study On Antioxidant Activities Of Proteins And Enzymatic Hydrolysates Of Eight Edible Fungi, Wang Yao-Ran, Zhao Yan, Chen Ming-Jie, Wei Chen-Ying, Zha Lei, Li Zhi-Ping

Food and Machinery

Objective: This study focused on the antioxidant activities of eight edible fungiproteins and their hydrolysates. Methods: Eight edible fungi proteins were hydrolyzed using alkaline protease. DPPH free radical scavenging activity, ABTS free radical scavenging activity, Fe2+ chelation rate and reducing power were used to evaluate antioxidant activity. Results: SDS-PAGE electrophoretic profile results indicated that alkaline protease was efficient in hydrolyzing proteins into low molecular weight peptides and amino acid; the antioxidant activity of the alkaline proteolysis product of Volvariellavolvacea was the highest with DPPH free radical scavenging ability (5 140.45±5.35) μg Trolox/g, ABTS free radical scavenging …
