Study of tabletting properties of modified rice starch prepared by spray drying technique and crosslinking reaction

Abstract

Among various locally available native starches, rice flour was found to be the most suitable to be developed into a directly compressible diluent. The starch was modified into the form of spherical starch aggregates by spray-drying technique and crosslinking reaction. Rice starch aggregates which were deproteinized and crosslinked for 6 hrs. before being spray-dried exhibited the best tabletting properties. When compared with other commercial modified starch products, modified rice starch derived by the process in this study gave higher tablet hardness with shorter disintegration time.
