性状：γ-环状糊精是由8个葡萄糖单位经α-1.4糖键连接成环形结构的糊精。水溶解度在25℃为23.2 g/100ml，比α-环状糊精和β-环状糊精高，适合包接更大分子团。
特性：溶解性高，适合包接更大分子团，与倍他环状糊精相比有非常好的水溶性，易溶于水，与倍他环状糊精相比，对各种极性有机溶剂有较高的溶解性,因此特别适用于医药品、日化、食品等行业.
用途：γ-环状糊精可以用作香料，甜味剂和颜料的载体。在化学领域的用途是一种有价值的化学试剂。当存在它的时候，荧光色素的荧光强度会显著增大，故可用于蛋白质、氨基酸的分析；还可用它来分离长链有机化合物、外消旋体等。此外由γ-环状糊精制成的吸附剂能用作色谱分析的吸附。还可以作络合剂,也可用于酶活性研究,组织培养剂。
