摘要: 研究对比了南极磷虾干虾头与虾壳中常规化学成分及其氨基酸、脂肪酸、矿物元素组成和氟含量。结果表明虾头和虾壳中粗蛋白含量分别为57.61%、46.98%;灰分含量分别为12.48%、14.26%;粗脂肪含量分别为5.16%、5.09%;虾头、虾壳中检出18种氨基酸,氨基酸总量分别为43.07%和47.03%,8种人体必需氨基酸的总含量为18.98%、20.39%,分别占氨基酸总量的43.18%和42.41%;虾头、虾壳中呈味氨基酸含量丰富,分别占氨基酸总量的36.12%和35.53%;虾头、虾壳中必需脂肪酸种类齐全,油酸、亚油酸、EPA和DHA含量丰富,不饱和脂肪酸含量较高,分别占总量的50.31%、51.72%;虾头、虾壳中含有多种矿物元素,包括钙、钾、钠、镁四种常量元素,以及铁、铜、锌、锰、硒等五种人体必需的微量元素,微量元素锌、硒含量较高;虾头、虾壳中氟含量分别为1430、1930mg/kg。Abstract: Chemical compositions and amino acids, fatty acids, mineral elements, fluorine in dried Antarctic krill head and shell were compared in this study.Results showed that the crude protein contents of the shrimp head and shell were 57.61%, 46.98%, ash contents were 12.48%, 14.26%, crude fat contents were 5.16%, 5.09%, respectively.Head and shell were detected 18 kinds of amino acid, total amino acids were 43.07% and 47.03%, respectively, in which the content of 8 kinds of essential amino acid to the human body were 18.98% and 20.39%, and accounted for 43.18%, 42.41% of the total amino acids.Besides, there were more flavor amino acids in head and shell, and contents accounted for 36.12% and 35.53% of the total amino acids.Except that, essential fatty acids in the head and shell were rich, more content in oleic acid, linoleic acid, EPA and DHA, and the unsaturated fatty acid content was high accounted for 50.31% and 51.72% of total fatty acids.Head and shell contained a variety of mineral elements, including calcium, potassium, sodium, magnesium and four kinds of major elements, meanwhile containing iron, copper, zinc, manganese, selenium, essential trace element.Fluorine contents in head and shell were 1430mg/kg and 1930mg/kg, respectively.
