黄原胶 (CAS No.11138-66-2)
- 物化性质
- 白色或浅黄色粉末，溶于水，尤其可在冷水中快速溶解，不溶于乙醇。水溶液具有低浓度高黏度特性，呈假塑性；在10–80℃黏度几乎不变，pH 3–11范围内黏度变化很小；对酸、碱、盐和酶解作用稳定。分子由D-葡萄糖、D-甘露糖、D-葡萄糖醛酸、乙酰基和丙酮酸构成，相对分子质量约2×10^6–5×10^7。
- 技术参数
- 外观为白色或浅黄色粉末，溶于水，不溶于乙醇。 1%水溶液的黏度约为明胶的100倍，具有低浓度高黏度特性。 水溶液在10–80℃黏度几乎不变；1%黄原胶溶液（含1%氯化钾）从25℃加热至120℃，黏度仅降低约3%。 在pH 3–11范围内黏度变化小于10%，耐酸、碱、盐及多种酶。 可溶于5%硫酸、5%硝酸、5%乙酸、10%盐酸和25%磷酸等酸性溶液，常温下稳定。
English description（英文原文，共 1824 字符）
Product Name:Xanthan Gum
English Name:Xanthan Gum
CAS No.:11138-66-2
Aliases:Corn sugar gum, Gum xanthan
Molecular Formula:(C35H49O29)n
Physical Properties:White or light yellow powder, soluble in water and readily dispersible in cold water, insoluble in ethanol. Aqueous solutions exhibit low concentration-high viscosity behavior and pseudoplasticity; viscosity remains almost unchanged between 10–80 °C and varies only slightly over pH 3–11. Stable to acids, alkalis, salts and enzymatic degradation. The molecule is composed of D-glucose, D-mannose, D-glucuronic acid, acetyl and pyruvate groups, with a relative molecular mass of about 2×10^6–5×10^7.
Uses:Widely used in the food industry as a thickener, suspending agent, emulsifier and stabilizer in baked goods, meat products, frozen foods, jams, beverages, ice cream, dairy products, jelly and confectionery. It improves water retention and softness in baked goods, tenderizes and enhances water-holding capacity in meat products, and provides thickening and suspension in beverages for a smooth mouthfeel. It can also be used in combination with guar gum, carrageenan and locust bean gum.
Technical Specifications:
Appearance: white to light yellow powder; soluble in water, insoluble in ethanol.
The viscosity of a 1% aqueous solution is about 100 times that of gelatin, showing low concentration-high viscosity characteristics.
Viscosity of the aqueous solution is almost unchanged between 10–80 °C; a 1% xanthan gum solution containing 1% KCl loses only about 3% viscosity when heated from 25 °C to 120 °C.
Viscosity variation is less than 10% over pH 3–11; resistant to acids, alkalis, salts and various enzymes.
Soluble in 5% sulfuric acid, 5% nitric acid, 5% acetic acid, 10% hydrochloric acid and 25% phosphoric acid; stable at room temperature.
