沙葱种子几种营养成分含量的研究

[目的]综合评价沙葱种子的营养价值。[方法]以野生沙葱种子为试验材料,采用气相色谱法、液相色谱法及常规分析法测定了沙葱种子中几种营养成分的含量。[结果]沙葱种子中脂肪和总糖含量较高,其次为淀粉,蛋白质含量较低;总糖中以多糖为主,占总糖的57.31%;富含Vc,含量达263.49 mg/100g FW。沙葱种子含有18种氨基酸,以谷氨酸含量最高,人体必需氨基酸占氨基酸总量的28.4%,必需氨基酸营养比较均衡,SRC为38.37;沙葱种子中不饱和脂肪酸含量为92.15%,人体必需脂肪酸含量为74.92%,亚油酸74.57%,PUFA/SFA比值为11.78。[结论]该研究结果为沙葱种子的综合开发利用提供了理论依据。

Study on Nutrient Component Content of Allium mongolicum Regel Seed

[Objective] The aim was to comprehensively evaluate nutrient value of Allium mongolicum Regel seed[Method] With the wild Allium mongolicum Regel seed as experimented material,a few nutrient component contents were determined by using the analytical methods of gas chromatography,liquid chromatography and general one.[Result] The contents of fat and total sugar in A.mongolicum were the highest,starch content was second one and that of protein was lower.The polysaccharide was dominated in total sugar,which accounted for 57.31% of total sugar.The contain of Vc was rich,up to 263.49 mg/100g FW.There were 18 kinds of amino acids contained in the seed of A.mongolicum,among which,the glutamic acid was highest,the essential amino acids for human body accounted up 28.4% of total ones,the nutrition of necessary amino acids was in equilibrium with SRC of 38.37.In A.mongolicum seed,the content of unsaturated fatty acid was 92.15%,the human essential fatty acid content was 74.92%,linoleic acid content was 74.57% and the PUFA/ SFA ratio was 11.78.[Conclusion] A theoretical basis was provided for the synthetic development and utilization of A.mongolicum seed by this research results.
