Xylitol Research and Applications
1、Introduction
Xylitol is a kind of sugar alcohol extracted from birch bark and other hardwood. It has three-dimensional cyclic structure, low calorific value, good solubility in water, stable under acidic conditions, non-toxic and harmless to human body. Xylitol can be used as sugar substitute and also has many medical and health care effects.
2、 Stereochemical Configuration and Polymerization
3、 Physicochemical Properties
(1) It has low calorific value and water absorption, and it is of strong hygroscopicity.
(2) Xylitol has a high solubility in water and ethanol, and it can form a strong hydrogen bond with water molecules.
(3) In strong acid conditions, xylitol remains stable.
(4) The melting point of xylitol is 92 °C.
4、Application
(2) Medical and health care products: Xylitol can reduce the absorption of cholesterol in the intestinal tract, and inhibit
the formation of caries. It also has the effect of improving human immunity, promoting gastrointestinal peristalsis and promoting metabolism.
(3) Food Industry: Xylitol can be used as thickeners, emulsifiers, stabilizers, anti-foaming agents and anti-staling agents to improve the texture and taste of food.
(4) Cosmetics: Xylitol has good moisture absorption and moisturizing effect. It can be used as a moisturizing agent in cosmetic products.
5、Conclusion
Xylitol has the advantages of low calorific value, good solubility, stable under acidic conditions, non-toxic and harmless to human body. It can be used as a substitute for sugar and also has other medical and health care effects. It has been widely used in food industry, medical and health care products and cosmetics.。
