Chemical formula: C42H70O35.xH2O Uses: antioxidants, stabilizers, Preservatives. Cyclodextrin is the most compelling applications in the food industry. Cyclodextrin has the protection of certain substances in anti-oxidation, anti-light, heat, anti-evaporation and the solid phase and other functions, it can be used as multifunctional food additives. Its main role: 1 in food processing and preservation of β-CD process can prevent all kinds of spices, oil, spices and other volatile substances volatile, long-term food smell the same. β-CD can be maintained easily oxidized, decomposed when exposed to light, when exposed to heat perishable pigments, amino acids and vitamins and other nutrients stability. 2. Β-CD to remove the fish, meat flavor and foods of additional nutrients such as vitamin B, after the unpleasant taste and smell of other foods, increased palatability of food, can also improve other sweeteners saccharin and cyclamate taste. 3. Β-CD for high oil content of beverages, such as: ice cream, coffee drinks and other foods can be emulsified to form a long-term stability of the emulsion transfer. If used in conjunction with the food emulsifier, emulsion better. 4. Β-CD can make the food preservative, preservative slow release, to improve corrosion protection, extended shelf life of food
