桂麻菜1号和桂麻菜2号的营养成分分析

【目的】明确桂麻菜1号和桂麻菜2号中硒、钙元素及鲜味和药效氨基酸的含量,为选育和推广富硒、高钙菜用黄麻品种提供参考依据。【方法】根据食品和蔬菜主要营养成分测定方法,分别测定、分析桂麻菜1号和桂麻菜2号鲜嫩茎叶的主要营养成分含量。【结果】桂麻菜1号和桂麻菜2号的蛋白质、膳食纤维、维生素(VB1、VB2、VB3、VC和VE)、钙和硒等营养成分含量明显高于叶菜类蔬菜相应指标的标准含量,其中,桂麻菜1号和桂麻菜2号的100 g鲜样中硒含量分别为11.00和15.00μg,达富硒蔬菜的上限要求,为普通蔬菜的7.97~45.45倍;钙含量分别为145.0和182.0 mg,膳食纤维含量分别为3.16和3.17 g,蛋白质含量分别为5.08和5.18 g。此外,桂麻菜1号和桂麻菜2号均含有17种氨基酸,总量分别为4.43和4.35 g/100 g FW,其中鲜味氨基酸含量分别占总氨基酸含量的43.34%和42.30%,药效氨基酸含量分别占总氨基酸含量的56.66%和57.70%,接近鲜样淮山药中鲜味氨基酸(47.66%)和药效氨基酸(52.34%)所占氨基酸总量的比例。【结论】桂麻菜1号和桂麻菜2号是富硒、高钙且具有保健功能的蔬菜,生产上可大力推广种植。

Nutritional components analysis on fresh leaves of vegetable jute varieties Guimacai 1 and Guimacai 2

Objective]The contents of calcium,selenium,delicious amino acids and medicative amino acids in Guimacai 1 and Guimacai 2 were detected in order to provide reference for breeding and promoting selenium-enriched and high calcium vegetable jute varieties.Method]The main nutritional components in fresh leaves Guimacai 1 and Guimacai 2 were measured and analyzed using the methods detecting main nutritional components in food and vegetables.Result]The content of proteins,dietary fiber,vitamins (VB1、VB3、VC、Vc、VE),calcium and selenium in Guimacai 1 and Guimacai 2 were higher than the corresponding standards for leaf vegetables.The contents of selenium were 11.00 and 15.00 μg in 100 g fresh sample of Guimacai 1 and Guimacai 2 respectively,which reached upper limit for selenium-enriched vegetables.The contents of selenium in Guimacai 1 and Guimacai 2 were as 7.97-45.45 times as those in common leaf vegetables.In Guimacai 1 and Guimacai 2,calcium contents were 145.0 and 182.0 mg,dietary fibers were 3.16 and 3.17 g and proteins were 5.08 and 5.18 g respectively.Moreover,17 kinds of amino acids were detected in Guimacai 1 and Guimacai 2,the total amount of amino acids were 4.43 and 4.35 g in 100 g fresh sample.Delicious amino acid accounted for 43.34％ and 42.30％ of the total and medicative amino acids accounted for 56.66％ and 57.70％ of the total respectively in Guimacai 1 and Guimacai 2.The proportion of the delicious amino and medicative amino acids in Guimacai 1 and Guimacai 2 were close to proportions of delicious amino acids(47.66％) and medicative amino acids (52.34％) in fresh yam.Conclusion] Guimacai 1 and Guimacai 2 are vegetables of selenium enrichment,high calcium and heahhcare function,and the cultivation of the vegetables can be promoted.
