超滤法制备高抗菌抗氧化活性带鱼蛋白亚铁螯合肽(Fe-HPH)的工艺研究
Preparing Ferrous Chelating of Hairtail Protein Hydrolysate (Fe-HPH) with High Antibacterial and Antioxidant Activity by URrafiltration
摘要
Abstract
In order to obtain ferrous chelating of hairtail protein hydrolysate (Fe-HPH) with highly antibacterial and anlioxidant activity, the ultrafiltration membranes of Mw cut-off 10, 5, 3, 1 ku, were used to fractionate Fe- HPH. The antibacterial and antioxidant activity were compared before and after the fractionation. Then an orthogonal test was de- signed to optimize fractionation conditions. Results: The filtrate of Mw cut-off 3 ku ultrafiltration membrane has the high antibacterial and antioxidant activity, and gives an antibacterial activity above 91.3% and DPPH radical scavenging activities above 84.6% with the optimum fractionation conditions as concentration 30%, pH 6.5, and temperature 35 ℃.关键词
