以添加微量元素锌的营养液培养苦荞芽菜,探讨对苦荞芽菜品质的影响。采用原子吸收光谱法、分光光度法、滴定法、氨基酸测定仪等方法,分析营养液加锌后培养苦荞芽菜的品质变化。与未加锌的对照相比,加锌后苦荞芽菜对锌的吸收增加,总糖、叶绿素、维生素C、可溶性蛋白的含量增加;还原糖、脂肪、粗纤维的含量降低;氨基酸含量也有所增加,且氨基酸配比更合理。试验结果表明:通过添加锌营养液培养,能极大地改善苦荞芽菜的品质。 The effect of trace elements on the quality of buckwheat sprouts was studied by culturing buckwheat sprouts with nutrient solution containing trace elements zinc. The changes of quality of buckwheat sprouts cultivated with nutrient solution plus zinc were analyzed by atomic absorption spectrometry, spectrophotometry, titration and amino acid analyzer. Compared with the control without zinc, the absorption of zinc by buckwheat sprout increased after zinc addition, the content of total sugar, chlorophyll, vitamin C and soluble protein increased; the contents of reducing sugar, fat and crude fiber decreased; Increase, and the amino acid ratio is more reasonable. The results show that: by adding zinc nutrient solution culture, can greatly improve the quality buckwheat sprouts.
