Effects of heat-moisture treatment on formation and characteristics of slowly digestible starch

HE Xiao-wei

Abstract

The formation and characteristics of slowly digestible starch in waxy corn starch were investigated under various heat-moisture treatment(HMT).The results showed that there were cracks and cave on starch granule surface on HMT and its birefringence decreased.The Brabender gelatinization parameter revealed the pasting temperature increased and peak viscosity decreased of all samples.Compared with the native starch,HMT improved the content of slowly digestible starch,the highest content was 9.25%.
