中华稻蝗酶解氨基酸营养液的研制

Making Amino Acid Nutrient Fluid from Enzymatic Hydrolysis of Oxya thinensis Thumberg

中华稻蝗体内富含蛋白质,其中必需氨基酸占氨基酸总量的64%～68%,且含多种微量元素、维生素,是一种很好的食物资源.为了开发中华稻蝗这一食物资源,使它成为便于人们接受的食物形式.采用木瓜蛋白酶对中华稻蝗成虫匀浆进行酶水解,制得稻蝗酶解液,在此基础上,研制稻蝗氨基酸营养液.经研究,确定了脱苦、脱臭、脱腥和脱异味的工艺条件:饱和β 环状糊精的体积分数8%,柠檬酸质量分数0.3%,苹果酸质量分数0.05%,清甜素质量分数0.01%.通过实验还解决了营养液长期放置过程中产生沉淀的难题.依据上述工艺条件,制得了口感、风味、色泽俱佳的氨基酸营养液.

Oxya chinensis thumberg, a kind of insects, contains not only a high content of protein,in which essential amino acids is 64%～68%, but also many kinds of vitamins, and trace elements. Therefore it is an excellent food resouce. In order to convert Oxya chinensis thumberg protein into an acceptable food, following experiments were carried out. First, the honmogenate of Oxya chinensis thumberg was hydrolysated by papsin and made into the enzymatic hydrolysis fluid, based on that,we got the amino acid nutrient fluid. Then, technical parameters were obtained in debittering, deodour and desmell of fish:saturated βcircle dextrin solution 8%,citric acid 0.3%,malic acid 0.05%, aspartame 0.01%. Finally, we solved technical problems of keeping amino acid nutrient fluid from producing sedimentation for long time of storage. Under these conditions, amino acid nutrient fluid was acceptable in taste,favour and color.
