Bioactive roe protein hydrolysates were prepared from Channa striatus (CRPH) and Labeo rohita (LRPH) and their functional and in vitro antioxidant properties evaluated. The degree of hydrolysis was 28.41% at 60min in channa and 18.85% in labeo roe concentrates at 90min. The yields of protein hydrolysates were 24.15% and 12.45% for channa and labeo roe protein concentrates, respectively. The protein content was identical (58%) in both roe protein hydrolysates. Protein solubility in channa was higher (90.48%) when compared to labeo (50.6%) at pH 12. Higher oil absorption capacity and foam stability were observed in CRPH and higher emulsifying capacity was found in LRPH. Smaller peptides of 12kDa were noted in both CRPH and LRPH. In vitro antioxidant activity was higher in CRPH than in LRPH as seen from DPPH radical scavenging and ferric reducing power.
从波纹唇鱼（CRPH）和罗非鱼（LRPH）中制备了具有生物活性的鱼卵蛋白水解物，并评估了它们的功能和体外抗氧化性能。在 60 分钟时，在 channa 中的水解度为 28.41%，在 labeo 鱼卵浓缩物中的水解度为 18.85%，在 90 分钟时。鱼卵蛋白水解物的产率分别为 24.15%和 12.45%。两种鱼卵蛋白水解物的蛋白质含量相同（58%）。与 labeo（50.6%）相比，在 pH 值为 12 时，channa 的蛋白质溶解度更高（90.48%）。在 CRPH 中观察到更高的吸油性和泡沫稳定性，而在 LRPH 中发现更高的乳化能力。在 CRPH 和 LRPH 中都观察到 12kDa 的小肽。从 DPPH 自由基清除和铁还原能力来看，CRPH 的体外抗氧化活性高于 LRPH。
