Abstract
Production and applications of difructose anhydride III (DFA-III) have attracted considerable attention because of its versatile physiological functions. Recently, large-scale production of DFA-III has been continuously explored, which opens a horizon for applications in the food and pharmaceutical industries. This review updates recent advances involving DFA-III, including: biosynthetic strategies, purification, and large-scale production of DFA-III; physiological functions of DFA-III and related mechanisms; DFA-III safety evaluations; present applications in food systems, existing problems, and further research prospects. Currently, enzymatic synthesis of DFA-III has been conducted both industrially and in academic research. Two biosynthetic strategies for DFA-III production are summarized: single- and double enzyme-mediated. DFA-III purification is achieved via yeast fermentation. Enzyme membrane bioreactors have been applied to meet the large-scale production demands for DFA-III. In addition, the primary physiological functions of DFA-III and their underlying mechanisms have been proposed. However, current applications of DFA-III are limited. Further research regarding DFA-III should focus on commercial production and purification, comprehensive study of physiological properties, extensive investigation of large-scale human experiments, and expansion of industrial applications. It is worthy to dig deep into potential application and commercial value of DFA-III.
