Description

Resistant starch (RS), isolated by hydrolysis with Termamyl, protease and amyloglucosidase, of fivecycle autoclaved rice was purified by size exclusion
chromatography. Structural characterization by b-amylolysis,
13C NMR and methylation followed by GC-MS analysis revealed RS to be a linear (1]4)- a-D-glucan,originating probably from amylose. Its molecular weight was low, 1.20!106 Da, and amounted to 7400 D-glucose residues. X-ray diffraction measurements showed RS to have both B-type and V-type diffraction patterns. Differential scanning calorimetry data revealed the thermal stability characteristics of RS. The undigested material (equivalent to RS) recovered from
the ileum of rat intestine exhibited an almost comparable
GPC profile, molecular weight and lmax characteristics
with those of in vitro isolated RS.
