豆天蛾幼虫水解试验研究

以豆天蛾幼虫为原料，用AS1．398中性蛋白酶、木瓜蛋白酶和复合风味蛋白酶为水解酶，分别研究其水解特性，最后确定复合风味蛋白酶为最优水解酶，其最优水解方案：温度为50℃、pH=6.5、时间为10h、加酶量为40LAPU／g。按此方案进行水解，重复3次，得到平均水解率为32．54％，蛋白质利用率为82．36％，取得较理想的水解效果。     

豆天蛾氨基酸及脂肪酸分析与评价

对豆天蛾幼虫氨基酸及脂肪酸组成进行了分析测定,结果表明:豆天蛾幼虫含有18种AA和8种EAA,EAA/TAA为53.34%,属于优质完全蛋白质昆虫。豆天蛾幼虫不饱和脂肪酸含量61.74%,其中亚麻酸和油酸的含量较高,亚麻酸含量高达34.11%;饱和脂肪酸含量36.43%,其中棕榈酸的含量较高。     

Nutritional evaluation of protein from Clanis bilineata (Lepidoptera), an edible insect

BACKGROUND: This study was carried out to determine the nutritive quality of protein from Clanis bilineata (CB), an edible insect. RESULTS: The protein content of dried CB was 685.3 g kg^?1 and its essential amino acid content was 528.4 g kg^?1, both of which are comparable to those of milk and eggs. Three groups of rats were fed diets containing either casein or CB protein (CBP) as protein source or a protein‐free diet for 10 days. The nutritional parameters measured for the group fed the diet containing CBP showed a positive nitrogen balance of 1.37, a net protein retention of 2.9 and a true digestibility of 95.8%, comparable to those measured for the group fed the casein diet. CONCLUSION: The results suggest that CBP may be a suitable alternative dietary protein source for humans. Copyright © 2011 Society of Chemical Industry     

豆天蛾多糖CBP3抗氧化活性研究

研究了豆天蛾多糖CBP3抗氧化活性,结果表明:豆天蛾多糖CBP3的还原能力与其浓度呈极显著正相关,y=0.1433x+0.0029,R2=0.9918;豆天蛾多糖CBP3与O-2·清除率显著相关,y=10.865x+1.7857,R2=0.9719,IC50=591μg/mL;豆天蛾多糖CBP3与·OH清除率极显著相关,y=20.129x-12.489,R2=0.9978,IC50=536μg/mL。结论:豆天蛾多糖CBP3具有良好的体外抗氧化活性。     

豆天蛾主要营养成份的分析与评价

对豆天蛾幼虫的粗蛋白、氨基酸、粗脂肪、脂肪酸含量进行了测试分析,结果如下;幼虫粗蛋白含量为６５．５％,必需氨基酸占总量氨基酸的５２．８４％,半必需氨基酸占９．７０％,粗脂肪含量２３．６８％,Ｃ１６－Ｃ１８脂肪酸占总脂肪酸的９９％以上。不饱和脂肪酸为６４．１７％,其中亚麻酸达３６．５３％,与鸡蛋、牛奶及大豆相比,豆天蛾表现了较高的蛋白质、必需氨基酸及必需脂肪酸含量,尤其是Ｃ１６：３亚麻酸含量高,因而     

豆虫草活性成分测定

以豆虫为寄主接种蛹虫草菌种,培育出豆虫草,比较了豆虫草与蚕蛹虫草、冬虫夏草的主要活性成分.结果表明：豆虫草的虫草素是冬虫夏草的35倍,虫草及其菌核的腺苷含量与冬虫夏草的相当,豆虫草SOD酶活性是冬虫夏草的1.5倍,豆虫草所含有的多糖是普通蚕蛹虫草的2倍.豆虫草是一种有良好前景的虫草新资源.
