摘要

利用虹鳟鱼内脏蛋白酶(5和15单位/g虾壳)从香蕉虾副产物中回收海洋生物活性化合物胡萝卜素蛋白。随着酶浓度的增加,胡萝卜素蛋白的产量增加,达到51.6%,这与酶解程度的增加是一致的。水解产物的蛋白质和脂质含量分别为79.6%和9.4%。与对照组(254 mg/g)相比,水解液具有高营养价值,必需氨基酸含量高(465 mg/g)。在两次体外实验中,胡萝卜素蛋白显示出剂量依赖性的抗自由基活性增加,对DPPH和ABTS清除活性的效率分别为94%和57%。蛋白酶提取胡萝卜素蛋白在不同浓度下对ACE的抑制作用均高于对照组(p<0.05)。本研究结果表明,香蕉虾中胡萝卜素蛋白具有清除自由基和抗高血压的双重作用,其必需氨基酸含量较高,是一种高附加值的营养食品原料。

Carotenoprotein from by-product of banana shrimp (Penaeus merguiensis) extracted using protease from viscera of rainbow trout: antiradical and angiotensin I-converting enzyme inhibitory activity
Carotenoprotein as a marine bioactive compound was recovered from banana shrimp by-product using protease from rainbow trout viscera at various levels (5 and 15 units/g shrimp shell). The yield of carotenoprotein increased with increasing enzyme concentration up to 51.6%, which was consistent with increasing degree of hydrolysis. Protein and lipid content of the hydrolysate was 79.6 and 9.4 percent, respectively. The hydrolysate had a high nutritional value with a high amount of essential amino acids (465 mg/g) compared to the control (254 mg/g). The carotenoprotein exhibited a dose-dependent increase in antiradical activity measured by two in vitro assays, with an efficiency of 94 and 57 percent for DPPH and ABTS scavenging activities, respectively. Protease-extracted carotenoprotein showed higher ACE inhibiting effect than the control at different concentrations (p<0.05). The results from this study showed that carotenoprotein from banana shrimp have both radical scavenging activity and antihypertensive properties and a high content of essential amino acids, and could be good source for value-added nutritive food ingredients.
