摘要
采用国标和农业部颁布的标准方法对新疆产青岛大花花和叶中的营养成分进行了测定。结果显示,青岛大花花和叶营养成分丰富,其中蛋白质含量分别为16.9%和18.1%,粗纤维含量分别为14.8%和12.7%,总糖含量分别为3.26%和5.44%;花和叶中均含有17种氨基酸,氨基酸总量分别为7.75%和9.65%,其中必需氨基酸占各自氨基酸总量的34.32%和43.94%,药效氨基酸占各自氨基酸总量的68.26%和63.52%;花和叶中矿质元素丰富,且钾含量分别为钠含量的147.5和84.8倍,具有典型的高钾低钠特征。结果表明,新疆产青岛大花花和叶均具有较高的营养价值和保健价值,且叶的总体营养品质略优于花。
Nutritional ingredient analysis of the flowers and leaves of Tsingtao flower from Xinjiang was carried out by GB and NY methods.The results showed that the flowers and leaves contained rich nutritional components.Of which,the protein contents in flowers and leaves were 16.9% and 18.1%,crude fiber contents were 14.8% and 12.7%,total sugar contents were 3.26%and 5.44%,respectively.Seventeen kinds of amino acids were determined in flowers and leaves,and the contents of total amino acids were 7.75% and 9.65%,respectively.The essential amino acids in flowerss and leaves accounted for 34.32% and 43.94%of their total amino acids,and the medicinal amino acids accounted for 68.26% and 63.52% of their total amino acids,respectively.The content of potassium in flower and leaves were 147.5 and 84.8 times than that of sodium,respectively,which was the typical characteristic of high potassium low sodium.The results indicated that the flowers and leaves of Tsingtao flower from Xinjiang had the higher nutritional value and healthcare value,and the overall nutritional quality of the leaves was better than that of the flowers.
