柞蚕雌蛹与雄蛹的营养组分及含量分析

Nutritional Components and Content Determination in Female and Male Pupae of Antheraea perny

[目的]客观评价柞蚕蛹的营养价值,为其在食品及保健品领域的应用提供理论依据。[方法]对新选育的柞蚕品种川柞1号柞蚕蛹的营养价值作出科学评价,对该柞蚕雌蛹和雄蛹的主要营养成分进行测定分析。[结果]试验表明,新鲜雌蛹和雄蛹中蛋白质质量分数分别为12.11%和10.80%,氨基酸质量分数分别为10.48%和8.35%,均含有8种人体必需氨基酸,必需氨基酸分别占总氨基酸质量的38.49%和36.36%,必需氨基酸质量比分别为395.1、334.2 mg/g。新鲜雌蛹和雄蛹中的粗脂肪含量分别为4.22%和6.40%;均含有K、Ca、Na、Mg、Cu、Zn、Fe、Mn、Se、Cr等多种矿物质元素,均未检测出Hg、Pb和As等重金属元素。此外,柞蚕雌蛹、雄蛹中还含有多种维生素,包括维生素A、维生素B1、维生素B2、维生素C、维生素E等,其中维生素B2、维生素C、维生素E的含量较高。[结论]综合分析检测数据认为,柞蚕雌蛹和雄蛹均属于优质蛋白质食品,且雌蛹的营养价值略优于雄蛹。

[Objective] The aim was to evaluate nutritional value of pupae of Antheraea perny, to provide theoretical basis for its application in food and health products.[ Method] The nutritional value of Chuanzuo 1 was scientifically evaluated, the main nutritional ingredients in both male and female pupae of Chuanzuo 1 were determined.[ Result] The result showed that the main ingredients and their contents in female and male pupae were as follows： mass fraction of proteins was 12.11% and 10.80% respectively, mass fraction of amino acids was 10.48% and 8.35% respectively, there were 8 kinds of essential amino acids for human in both female and male pupae, the ratio of essential amino acids to total amino acids was 38.49%and 36.36% respectively.The essential amino acid mass ratio of female and male pupae protein was 395.1, 334.2 mg/g respectively.The mass fraction of crude fat was 4.22% and 6.40% respectively.Pupae of both female and male had various mineral elements including K, Ca, Na, Mg, Cu, Zn, Fe, Mn, Se and Cr.No heavy mineral elements, such as Pb, Hg and As, were detec-ted.Besides Antheraea pernyi female and male pupae also contains a variety of vitamins, including vitamin A, vitamin B1 , vitamin B2 , vita-min C, vitamin E, the vitamin B2 , vitamin C, vitamin E content is high in pupae of Antheraea perny.[ Conclusion] Based on these data, it was concluded that both female and male pupae of Antheraea pernyi are excellent protein food, and the nutritional value of female pupae was slightly higher than that of the male pupae.
