Isomaltulose is a kind of food sweetener formed by white granulated sugar as raw material, transformed by sucrose isomerase, and then condensed, crystallized and separated. It is white crystal, odorless, sweet, and sweetness is about 42% of that of sucrose. The sweetness is pure, basically the same as sucrose, without bad aftertaste. This kind of sugar decomposes very slowly in the intestine, which balances the absorption and utilization of sugar by the human body, does not increase the blood sugar concentration, but also stimulates the growth and reproduction of beneficial bacteria in the intestine, and optimizes the human digestive system. It is very suitable for use in candies, beverages and various foods.
