摘　　要：研究了一种新的高纯度低聚异麦芽糖(IMO)生产方法。利用益生菌添加甜菜碱进行乳酸发酵,将可发酵性糖葡萄糖、果糖和麦芽糖转化为乳酸,使原料IMO等级由IMO-50提高到IMO-90,发酵液无需进行菌体分离即可用于食品加工。A new method for the production of high-purity isomalto-oligosaccharides （IMO） by the lactic acid fermentation using probiotic strains was demonstrated. With the addition of betaine and the fermentation of sugars such as glucose, fructose and maltose into lactic acid by probiotics, the low-purity IMO-50 was effectively converted into the high-purity IMO-90. There was no need to separate the strains after conversion. The method is an easy way to manufacture edible products.
