Difructose anhydride III (DFA III), the smallest cyclic disaccharide, consists of two fructose residues. DFA III is a hydrolysate of inulin and is rarely found in nature. Industrial interest in DFA III as a low-calorie sugar substitute is increasing. The present review describes the properties and physiological functions of DFA III as well as its commercial importance. Focus is also given on the biological production of DFA III from inulin, which contains enzyme resources, inulase II properties, and the capacity for mass DFA III production. Inulase II as an industrial enzyme and its molecular evolution are discussed as well. The aim is to better understand commercial-scale DFA III production as a food product.
三异麦芽酮糖醇（DFA III），最小的环状二糖，由两个果糖残基组成。DFA III 是菊粉的水解产物，在自然界中很少见。作为低热量糖替代品，工业界对 DFA III 的兴趣日益增加。本综述描述了 DFA III 的性质和生理功能及其商业重要性。重点还放在菊粉中 DFA III 的生物生产上，其中包含酶资源、菊粉酶 II 的性质和大规模 DFA III 生产的能力。菊粉酶 II 作为一种工业酶及其分子进化也进行了讨论。目的是更好地理解作为食品的商业化 DFA III 生产。
