The aqueous solution of xylitol has good thermal stability and is an ideal sweetener for making health drinks suitable for diabetics. It is a food sweetener allowed for use in accordance with my country’s GB2760-1996 regulations. It can replace glucose and fructose as energy sources for the body and is also an important substance for synthesizing nucleic acids and detoxifying in the body. Because diabetics have insufficient insulin secretion, glucose cannot be converted into 6-phosphate glucose, and the metabolism of xylitol has nothing to do with insulin, so it will not increase the blood sugar level of diabetics. Xylitol also has the special function of inhibiting the formation of ketone bodies, which can reduce the transaminase of patients with liver disease, enhance liver function, and promote fat metabolism. The oral absorption of this product has large individual differences, which may be related to intestinal bacteria, contents, and genetic factors. This product is almost completely metabolized in the body and rarely excreted in the urine in its original form. It is clinically used to supplement calories and body fluids, improve sugar metabolism, and eliminate ketonemia when the body lacks insulin. It is an effective regulator of abnormal diabetes metabolism. At conventional doses, it has no obvious effect on the liver and kidneys, but when taken in large quantities, it can cause osmotic diarrhea and water balance disorders. The daily intake of xylitol should be less than 50-70 grams. Xylitol can be used in the processing of condiments, beverages, jams, candies, cakes, etc. Since yeast and bacteria cannot utilize it, it can be used as a sweetener to prevent tooth decay and has an antiseptic effect.
