文摘

Enzymatic hydrolysis curves of starches were fitted to a logarithm of slope plot. The change in rate constant during digestion was observed. The individual existence of RDS and SDS was proven in amylosucrase-modified starch. The structure of starches was investigated before and after digestion. Amylopectin chain length determined the arrangement of each starch fraction.
