Trehalose
Trehalose------“Life Sugar”
With the unique bioactivity,especially many features such as the most stablity of natural disaccharides,high acid resistance, high heat resistance, low sweetness, stable crystallinity, low dental caries, tolerance and safety, so trehalose protect multiple large molecule and help organism to resist high temperature, cooling, dry, hypertonic, radiation and toxic substance,etc.
Application of Trehalose
ⅰUsed for reagent and diagnosed the stability of medicine in pharmaceutical fields.
ⅱ Used for raw material of cosmetics for resist skin dry and moisturize;
ⅲ Used for sugar substitute in food industry by its features such as irreducibility, moisture retention, freeze resistance and desiccation tolerance, etc.
