Isomaltooligosaccharide (IMO) is a kind of starch sugar. Its sugar powder is amorphous white powder, with a sweetness of 45%~50% of sucrose, pure sweetness and low calorie. It is an ideal substitute for diabetics. The viscosity of IMO is higher than that of sucrose at the same concentration and lower than that of maltose. It has good moisturizing properties and higher osmotic pressure. Therefore, it can be used in candies, pastries, and cold drinks to prevent starch aging, avoid the precipitation of glucose or sucrose, and give the product a moist, delicate, and soft taste. IMO can tolerate lower pH and higher temperature, and can be added to high-temperature sterilized foods or beverages with higher acidity. At the same time, IMO has bifidogenic properties, which help activate the immune system, stimulate intestinal peristalsis, improve defecation, reduce total chole...
