摘要
利用苯酚法、考马斯亮蓝G-250染色法、抗坏血酸法分别测定香蕉成熟过程中可溶性糖、可溶性蛋白、维生素C的含量变化以及淀粉用酸水解转化成葡萄糖后,测定葡萄糖含量,根据葡萄糖含量换算成淀粉含量.通过对比生、熟香蕉中可溶性糖、可溶性蛋白、维生素C、淀粉的含量来研究香蕉成熟过程中有机物含量的变化情况.结果显示:香蕉成熟过程中,可溶性糖、可溶性蛋白质含量均增加,而淀粉、维生素C含量却减少.
To use the method of phenol, coloring Coomassie brilliant blue G - 250 and ascorbic acid to determine respectively the changed content of soluble sugar, soluble protein and Vitamin C of process of mature banana, and determine the content of dextrose, after starch converts acid hydrolyze into dextrose, according to the content of dextrose change into the content of starch, research the changed condition of content organics of process of mature banana through compares raw banana to ripe banana to obtain the content of starch of soluble sugar, soluble protein and Vitamin C. The result shows the content of soluble sugar and soluble protein of process of mature banana increase equally while starch and Vitamin C reduce.
