Abstract

The e�ect of removal of protein and lipids on the resistant starch (RS) content of processed rice and ragi has been studied. The percent recovery of RS increased signficantly (over 2±3-fold) after defatting and autoclaving. However, deproteinization did not show any major difference. Prolonged storage of gelatinized starch suspensions showed considerably more undigested mass even after extended α-amylolysis, probably due to the involvement of long unbranched chains of amylopectin in the formation of RS.Thermal characteristics of these processed flours/starches showed variable enthalpy values. X-ray diffraction data revealed both B-and V-type diffraction patterns for the isolated RS.
