8种原生蔬菜氨基酸组成及营养评价

对8种原生蔬菜氨基酸含量及组成进行分析测定，并采用模糊识别法和氨基酸比值系数分法对其蛋白质营养价值进行评价。结果表明，8种原生蔬菜氨基酸含量丰富，种类齐全，必需氨基酸含量较高，占总氨基酸含量的38.36%~44.08%；鲜味氨基酸占总氨基酸含量的21.46%~26.59%。模糊识别法评价蛋白质营养价值高低为：苦菜〉羽衣甘蓝〉九层塔〉紫背天葵〉番杏〉猫薄荷〉芹菜〉马齿苋〉马兰〉空心菜〉卷心菜〉生菜；用氨基酸比值系数分法评价，蛋白质营养价值高低为：番杏〉芹菜〉苦菜〉马兰〉九层塔〉紫背天葵〉羽衣甘蓝〉猫薄荷〉卷心菜〉生菜〉马齿苋〉空心菜。2种评价方法的评价结果不尽一致，但是总体上可以得出，原生蔬菜氨基酸组成平衡且优质，其蛋白质营养价值高于 所选的普通蔬菜对照品种，具有较高的开发利用价值。

Amino Acid Composition and Nutrition Evaluation for Eight Original Ecology Grown Vegetable Species

Eight original ecology grown vegetables were studied on their amino acid compositions to evaluate their protein nutritive quality. The results showed that these vegetables were rich in the content of amino acid （AA）.The ratio in essential amino acids （EAA） to total AA were varied between 38.36%~44.08% in various vegetable species respectively, while the flavor amino acids （FAA） of total AA were 21.46%~26.59%.The protein nutritional value of those vegetables was evaluated with fuzzy discernment method and was ranked in order of balsam pear 〉kale 〉basil 〉gynura 〉tetragonia 〉catnio 〉celery 〉purslane 〉ma lan 〉water spinach 〉cabbage 〉lettuce. However, with amino acid coefficient index method, the protein nutritional vatlue was ranked in order of tetragonia 〉celery 〉balsam pear 〉ma lan 〉basil 〉gynura 〉kale 〉catnip 〉cabbage 〉lettuce 〉purslane 〉water spinach.The results showed that the protein quality of original ecology grown vegetables was far superior to that of the contrast.
