荷兰的一个研究小组，利用基因工程技术，将甜菜中的蔗糖分子，转变为果聚糖分子，从而培育出了可生产低热量糖的转基因甜菜。这种甜菜，有望为廉价大量生产果聚糖提供方便。 果聚糖是由果糖形成的聚合物链，不容易被人体内的酶所消化。现在，生产商行主要是利用生化技术合成果
A Dutch team used genetic engineering to transform sucrose molecules in beets into fructan molecules, thereby creating a transgenic sugar beet that produces low-calorie sugars. This beet is expected to provide convenience for mass production of fructan at low prices. Fructan is a polymer chain formed from fructose that is not easily digested by enzymes in the body. Now, producers mainly use biochemical technology to synthesize fruit
