益生菌乳酸发酵法生产高纯度低聚异麦芽糖

Production of High-Purity IMO by Lactic Acid Fermentation Using Probiotics

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。

Abstract:

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.
