环糊精Cyclodextrin(简称CD),又称“Schardinger dextrin”,是目前引人注目的一种食品和药用新型包合材料。它的制法虽在上世纪末就有报道,但其工业生产和实际应用则是近几年来的事。它是由淀粉经酶解、环合后得到的一种产物,由六个以上的葡萄糖以α-1,4糖甙键连结的环状低聚糖化合物,为水溶性、非还原性的白色结晶性粉末,其中最常见的是α-环糊精、β-环糊精、γ-环糊精,分别由6个、7个和8个萄葡糖分子构成。经X-线衍射和核磁共振证实了它的立体结构是环状中空园筒形,园筒内为疏水区,空洞的直径随环糊精种类而异,约为
Cyclodextrin (CD), also known as “Schardinger dextrin”, is a new type of inclusion material for food and medicine. Although its system of law was reported at the end of the last century, its industrial production and practical application have been in recent years. It is starch by enzymolysis, after cyclization obtained a product from more than six glucose α-1,4 glycosidic bond linkage of cyclic oligosaccharide compounds, water-soluble, non-reducing white Crystalline powders, the most common being α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, are composed of 6, 7 and 8 glucose molecules, respectively. X-ray diffraction and nuclear magnetic resonance confirmed its three-dimensional structure is annular hollow cylindrical shape, cylindrical hydrophobic region, the diameter of the cavity varies cyclodextrin type, about
