塔格糖 (CAS No.87-81-0)
- 物化性质
- 白色无臭结晶性粉末，味甜，甜度为等量蔗糖的92%，所产生的热量仅为蔗糖的1/3（1.5 kcal/g）。熔点132~135℃，1%水溶液比旋光度[α]D20为-6±1°（c=5, H2O）。溶于水，水中溶解度58.3%（20℃）、62%（30℃），几乎不溶于乙醇和甲醇。玻璃化温度15℃，易结晶，吸湿性低，保湿性强。耐酸性强，在pH 2~7范围内稳定。易发生焦糖化反应和美拉德褐变反应。天然存在于酸乳、奶粉等乳制品中。
- 技术参数
- 含量≥99.8% 熔点132~135℃ 比旋光度[α]D20 -6±1°（c=5, H2O） 水分及灰分符合食品级标准

Product Name:D-Tagatose
English Name:D-Tagatose
CAS No.:87-81-0
Aliases:D-(-)-Tagatose
Molecular Formula:C6H12O6
Physical Properties:White odorless crystalline powder with a sweet taste. Its sweetness is about 92% of that of sucrose, while the caloric value is only one-third of sucrose (1.5 kcal/g). Melting point 132~135℃. Specific rotation [α]D20 -6±1° (c=5, H2O). Soluble in water with a solubility of 58.3% at 20℃ and 62% at 30℃; practically insoluble in ethanol and methanol. Glass transition temperature 15℃. It tends to crystallize, has low hygroscopicity and strong moisture retention. It is stable in the pH range of 2~7. Susceptible to caramelization and Maillard browning. Naturally present in dairy products such as yogurt and milk powder.
Uses:Tagatose is a rare monosaccharide and an epimer of fructose, with sweetness close to sucrose but lower calories, making it suitable as a low-calorie sweetener. It is widely used in dairy foods, meat products, bakery foods, flour-based foods and seasoning foods. In the pharmaceutical field, it can be used in health foods, fillers and pharmaceutical raw materials. In cosmetics, it serves as a moisturizing agent, and in tobacco products it can replace glycerin as a flavoring, antifreeze and moisturizing agent for cut tobacco.
Technical Specifications:
Content ≥99.8%
Melting point 132~135℃
Specific rotation [α]D20 -6±1° (c=5, H2O)
Moisture and ash content meet food-grade standards
Packaging: 25kg/drum
