摘　　要：为探究不同蒲公英苗菜的营养价值,采用自然光照射和完全遮光两种处理对蒲公英进行栽培,对采收苗菜的基本营养成分、氨基酸和矿质元素含量等指标进行测定。结果表明,自然光照射处理的蒲公英苗菜粗脂肪含量、可溶性蛋白含量和维生素C含量均高于遮光处理,而遮光处理的蒲公英苗菜粗纤维含量、有机酸含量较高;遮光处理蒲公英苗菜矿质元素锌含量较高,自然光照射处理蒲公英苗菜铁、镁和钙含量较高;两种苗菜富含多种氨基酸,检测出了16种水解氨基酸,其中包含人体必需8种氨基酸中的7种,部分氨基酸含量差异较显著,遮光处理的苗菜天冬氨酸、谷氨酸含量较高,是自然光照射处理苗菜的3.21和1.31倍,而自然光照射处理苗菜富含脯氨酸和亮氨酸,分别比遮光处理苗菜提高77.11%和64.55%。综上所述,两种处理方式会使蒲公英苗菜的营养价值有一定差异,可满足人们不同的食用口感和营养需求。In order to explore the nutritional value of different dandelion seedlings,natural light irradiation and fully shaded light were used to cultivate dandelion,then contents of basic nutrients,amino acids and mineral elements of dandelion seedlings were detected and analyzed.The results showed that the contents of crude fat,soluble protein and vitamin C in natural light treatment were higher than those in shading treatment,while the contents of crude fiber and organic acids in shading treatment were higher;The mineral elements with high zinc content was shading treatment,and that with high contents of iron,magnesium and calcium was natural light treatment;Two kinds of dandelion seedlings richly contain various amino acids,16 kinds of hydrolyzed amino acids were detected,they contained 7 essential amino acids for human body.The contents of individual amino acids were significantly different,the seedlings treated with shading were rich in aspartic acid and glutamic acid,which were 3.21 and 1.31 times higher than those in natural light treatment.The contents of proline and leucine in natural light treatment were higher,which were 77.11%and 64.55%higher than that in shading treatment respectively.The nutritional value of dandelion seedlings was different by two treatments,and could meet people's different tastes and nutritional needs.
