Functionality of Cyclodextrins in Encapsulation for Food Applications

Cyclodextrins (CD) are cyclic oligosaccharides containing 6, 7 or 8 glucose units (α, β or γ-CD, respectively) in a truncated molecular shape. Their cyclic molecular structure contains a hydrophilic surface and a hydrophobic cavity at the center that can interact (host) with external hydrophobic compounds (guest molecules). Cyclodextrins have been categorized as Generally Recognized As Safe (GRAS) in the USA, “natural products” in Japan, and as “novel food” in Australia, New Zealand and EU ...
