Beta Cyclodextrin CAS 7585-39-9
There is a hole in the middle of the molecular structure of betacyclodextrin, and the outer part of the secondary alcohol light group of the molecular glucose bond is hydrophilic or polar, while the inner part of the primary alcohol light group is hydrophobic (lipophilic) or non-polar. Because of the special properties of the polarity of the two on the structure of D, it can be bonded with many smaller molecular compounds in the hole to form a inclusion complex. Industrial applications take advantage of this unique property of caves.

Betacyclodextrin is a good excipient, flavor modifier, stabilizer, emulsifier, preservative and quality improver in industrial production. It is widely used in pharmaceutical industry, food industry, daily chemical industry and other fields to improve product stability and product quality.
In the field of pharmaceutical industry
Increase the stability of the drug, reduce the irritation and side effects of the drug, cover up the odor, and increase the solubility of the drug
Application in the food industry
The stabilizer and sustained-release agent of spicy spices, edible spices, flavors and pigments, moisture-proof and moisturizing, enhancing anti-corrosion, removing bitter and deodorizing, foaming and emulsifying, and extending shelf life
Application in daily chemical industry
Reduce side effects, improve stability and prolong fragrance retention
Q: What are the differences between the three basic cyclodextrins?
A: Alpha cyclodextrin, beta cyclodextrin, and gamma cyclodextrin are the three commonly used basic cyclodextrins, and their raw materials are tapioca starch or corn starch. The difference is reflected in the following two points:
First, the diameter of the cyclodextrin cavity is different;
Second, the solubility of cyclodextrin in water is different.
