Abstract: Cyclodextrin molecule has a unique structure and can form inclusion compounds with various guest substances. It has a wide range of applications in the food industry, such as improving the stability of food ingredients, extending the storage period of food, increasing the solubility of food ingredients, and maintaining the flavor of the food itself unaffected. This paper reviews the classification and properties of cyclodextrin inclusion compounds, their preparation methods, and their applications in the food industry.
Keywords: cyclodextrin; inclusion compound; solubilization; food industry
環(huán)糊精(Cyclodextrins,CD)是直鏈淀粉在糖基轉移酶作用下產生的環(huán)狀低聚糖的總稱,通常是指由6~12個D-吡喃葡萄糖基團通過α-1,4糖苷鍵連接而形成的大環(huán)分子,其呈現截頂圓錐狀三維結構,具有疏水空腔和親水外壁,可以通過分子間相互作用與各種小分子或聚合物形成主-客體包合物,從而對客體具有增溶、控制釋放和活性保護等功能。(剩余4575字)
