Maltose dilution is a common sweetener with no special use, and its main use is in food processing to provide sweetness and calories. Maltodextrin, also known as caramel, is a type of sugar made by using the enzyme saccharase from malt to act on the starch in rice. It is light yellow in appearance and is used from time to time in candy, pastries, and other snacks. Maltose is a disaccharide with a very high glycemic index, its absorption rate is second only to glucose and other monosaccharides, and maltose is also a high-calorie food, with 100g of maltose having about 400 calories. It is very unsuitable for weight loss and diabetic patients. According to the latest dietary guidelines, a person should not consume more than 50g of added sugar in a day, preferably under 25g. Therefore, even healthy people, who are not at risk of diabetes and do not need to lose weight, need to control the intake of maltose.
