Antioxidative Activities of Hydrolysates from Duck Egg White Using Enzymatic Hydrolysis

Antioxidative activity of hen egg ovalbumin hydrolysates.

To evaluate the antioxidative activity of the hydrolysates of ovalbumin, the antioxidative activities of the enzymatic extracts were evaluated using three different methodologies scavenging assays such as superoxide anion, hydroxyl radical, and inhibitory oxidation of linoleic acid in vitro, and the activities of SOD, GSH-PX, CAT and the level of MDA were determined in serum and liver of aged m...

Characterization of casein hydrolysates derived from enzymatic hydrolysis

BACKGROUND Casein is the main proteinaceous component of milk and has made us interest due to its wide applications in the food, drug, and cosmetic industries as well as to its importance as an investigation material for elucidating essential questions regarding the protein chemistry. Enzymatic hydrolysis is an important method commonly used in the modification of protein structure in order to ...

Antioxidant activities of chick embryo egg hydrolysates

Chick embryo egg hydrolysates (CEEH) were obtained by enzymatic hydrolysis of chick embryo egg in vitro-simulated gastrointestinal digestion. The antioxidant activities of CEEH were investigated by employing three in vitro assays, including the 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulfonate)/1,1-diphenyl-2-picrylhydrazyl (ABTS/DPPH)/hydroxyl radical-scavenging assays. The radical-scavenging e...

Multiple lysozymes of duck egg white.

Lysozyme was purified from a pooled sample of Peking duck egg whites by ion exchange chromatography and gel filtration. Three different lysozymes were found, and each was shown to be pure by several criteria. The three enzymes were like chicken lysozyme in molecular size and specific activity, although they could be distinguished from it, as well as from one another, by electrophoretic and immu...
