What is Gamma Cyclodextrin?
Cyclodextrin, abbreviated as CD, is a non-toxic polymer of glucose. It appears as a white powder with high water solubility and bioavailability, finding applications across multiple fields. Common cyclodextrins include alpha cyclodextrin, beta cyclodextrin, and gamma cyclodextrin.
Gamma Cyclodextrin (γ-cyclodextrin, γ-CD) is a compound formed when glucose polymers such as starch, glycogen, malt, and oligosaccharides serve as substrates, catalyzed by cyclodextrin glycosyltransferase.
Gamma Cyclodextrin exhibits high water solubility, a defining characteristic of this substance. For example, while many chemical powders have low solubility-dissolving only a fraction of a gram per 100 milliliters-γ-cyclodextrin achieves a solubility of 23g/100ml at room temperature (25°C). This property establishes its foundation for applications in the food industry.
Gamma-Cyclodextrin features a hollow molecular structure with a central cavity measuring 9.5 Å in diameter (Å is a unit of length, where 1 Å = 0.01 nanometers).
Gamma Cyclodextrin Benefits
1. High-purity gamma cyclodextrin delivers consistent efficacy. For substances with low bioavailability, such as resveratrol and coenzyme Q10, gamma cyclodextrin enhances their absorption.
2. For ingredients with bitter or unpleasant flavors-such as ginseng juice or ginseng extract-gamma-cyclodextrin encapsulates bitterness to mask undesirable tastes, facilitating palatable product development.
3. Gamma-cyclodextrin facilitates the separation of long-chain organic compounds and supports analytical work involving proteins and amino acids.
