Xylitol, also known as pentapentanol or five-carbon alcohol, is a pentahydric alcohol and is a monosaccharide compound. It is xylose obtained by hydrolysis of plant fiber raw materials. Hydroxy linear polyols.
Naturally found in bananas, strawberries, carrots, bayberry, onions, lettuce, cauliflower, spinach, mushrooms.
Xylitol looks like a slightly sweet orthorhombic crystal (stable) or monoclinic (metastable) of white sugar. Soluble in water, soluble in ethanol and pyridine solvents. Sweet and cool, easily soluble in water, ethanol, slightly soluble in methanol. The sweetness and calorific value are similar to those of sucrose, and it is an excellent sugar substitute for sucrose fasting patients. Hygroscopic. The relative molecular mass is 152.15.
1. Xylitol does not produce Maillard browning reaction with amino acids, proteins, etc., so it is often used as a surface sweetener for baked goods; it dissolves in water to absorb heat, has a cool taste when eaten, and does not cause caries. It is also suitable for diabetes. It can be used in cakes, beverages and candies to replace sucrose, and it can be used in moderation according to production needs.
2. Because of its chelation effect, and not affected by yeast and lactic acid bacteria, it has the function of preventing dental caries, so it can be used as a toothpaste additive;
3. It can also be used as a raw material for chemicals, coatings and paints; it can be used to prepare surfactants, emulsifiers, demulsifiers, various alkyd resins, coatings, varnishes, etc. Esters formed with synthetic fatty acids are non-volatile plasticizers. Xylitol can replace glycerin and is used in papermaking, daily necessities and national defense industries.
