European eel proteins hydrolysates (EPHs) were produced from A. anguilla muscle protein and protein isolate using Purafect®, goby crude proteases and B. invictae proteases. EPHs had high protein contents and displayed diverse molecular mass distributions. Muscle protein hydrolysates (MPHs) and protein isolate hydrolysates (PIHs) obtained both by Purafect® had the highest antibacterial activity. PIHs obtained by B. invictae proteases had the highest emulsifying stability. MPHs and PIHs obtained by goby proteases and PIHs obtained by B. invictae proteases had higher chelating effects. MPHs obtained by B. invictae proteases and PIHs obtained by Purafect® had the highest ability to prevent bleaching of β-carotene at 4 mg/ml (96.68% and 93.66% respectively). The maltodextrin-muscle protein hydrolysates dispersions were totally stable by the creaming index and the zeta potential values (−36.73 and −42.53 mV) compared to the maltodextrin-protein isolate hydrolysates dispersions and had the best electrosprayability approving the best ability to form microcapsules.

欧洲鳗鲡蛋白水解产物（个EPH）得自制备A.鳗使用Purafect®肌肉蛋白和蛋白分离物，虾虎鱼粗蛋白酶和B. invictae蛋白酶。EPHs的蛋白质含量高，并且显示出不同的分子量分布。两者获得的肌肉蛋白水解物（MPHs）和蛋白分离物水解物（PIHs）具有最高的抗菌活性。B. invictae蛋白酶获得的PIH具有最高的乳化稳定性。虾虎鱼蛋白酶获得的MPH和PIH以及虫形芽孢杆菌蛋白酶获得的PIH具有更高的螯合作用。B. invictae获得的MPH通过Purafect®获得的蛋白酶和PIH具有最高的防止β-胡萝卜素漂白的能力，为4 mg / ml（分别为96.68％和93.66％）。相比于麦芽糊精-蛋白质分离物水解产物分散体，麦芽糖糊精-肌肉蛋白水解产物分散体的乳脂指数和ζ电势值（-36.73和-42.53 mV）完全稳定，并且具有最佳的电喷雾性，从而证明了形成微胶囊的最佳能力。
