Abstract

Germination is a natural and efficient method of starch modification.This study aimed to investigate the changes in adlay starch during the germination process.The structural and functional properties of the starch of the adlay were analyzed after the starch was extracted from the adlay at different time of germination.The findings revealed the emergence of noticeable holes and pores on the surface of adlay starch after germination, accompanied by a decrease in starch particle size.Moreover, solubility and swelling power of adlay starch were found to decrease.Amylose content first increased and then decreased and the ratio of A chain decreased.All adlay starch displayed A-type crystallinity.Furthermore, the water absorption, oil absorption, rapid digestion starch, and adhesiveness of adlay starch increased after germination, while enthalpy of gelati-nization, slow digestion starch, and resistant starch decreased and the hardness, cohesiveness, and gumminess of the starch gel decreased.This study highlights the ability of germination to regulate the edible quality of adlay and enhance the characteristics of adlay starch products.

Key words： adlay; starch; germination; pasting properties; in vitro digestion properties
