贮藏在胡萝卜中的碳水化合物主要是蔗糖、葡萄糖和果糖。蔗糖与还原糖的比率随品种而异,促成早熟类型通常还原糖含量较高而贮藏型则蔗糖含量较高。 促进早熟种“Super-Sprite”中,较高的酸性蔗糖转化酶活性与低水平的蔗糖贮藏是相关的。随着酸性蔗糖转化酶活性的降低,还原糖和 Carbohydrates stored in carrots are mainly sucrose, glucose and fructose. The ratio of sucrose to reducing sugar varies from breed to breed, which results in higher levels of reduced sugars and more sucrose content in precooked types. In promoting the precocious species “Super-Sprite,” the higher acid sucrose invertase activity is associated with low levels of sucrose storage. With the reduction of acid sucrose converting enzyme activity, reducing sugar and
