中文摘要: 以新鲜澳洲坚果花为原料,通过干燥工艺制备澳洲坚果花茶。分别测定其游离氨基酸含量和挥发性香气成分的组成。结果表明:在澳洲坚果花茶中共检测出游离氨基酸17种,人体必需氨基酸7种,该花茶中游离氨基酸配比不均衡,但其种类丰富,并且符合WHO/FAO推荐必需氨基酸组成比例,苏氨酸和脯氨酸含量高;其挥发香气成分共鉴定出29种,醇类3种,醛类8种,酯类4种,酸类4种,烃类5种,其他类化合物4种,所含化合物是:苯乙醇(29.2%)、苯苄醇(22.8%)、2-乙基己醇(8.2%)、苯甲醛(4.6%),庚醛(4.2%),月桂醛(3.7%),酞酸二乙酯(3.7%),壬酸(3.4%),癸醛(3%),六甲基环三硅氧烷(1.9%)等,他们构成了澳洲坚果花茶的特征香气。
Abstract:The macadamia scented tea was prepared from fresh macadamia flowers that be dried.The composition of amino acids and aroma components in the macadamia scented tea were analyzed,respectively.The results showed that 17 kinds of amino acids existed in the macadamia scented tea,7 of them were essential to human being.The free amino acid distribution in the scented tea is unbalanced,but the total free amino acids in this scented tea were rich in variety and high in content,and were in line with the essential amino acid composition recommended by WHO/FAO,which was a comprehensive drink.A total of 29 kinds of volatile aromatic compounds were identified,3 species of alcohol,8 species of aldehyde,4 species of esters,4 species of acids,5 species of hydrocarbons,4 species of other compounds,containing compounds,the compound were phenylethyl alcohol(29.2%),benzene,benzyl alcohol(22.8%),2-ethyl hexanol(8.2%),benzene,formaldehyde(4.6%),heptyl aldehyde(4.2%),laurel aldehyde(3.7%),ethyl phthalate(3.7%),pelargonic acid(3.4%),decanal(3%),three six methyl siloxane(1.9%),etc.They make up the characteristic aroma of macadamia scented tea.
