Abstract

Response Surface Methodology (RSM) was used in the optimization of the parboiling condition of foxtail millet grains with its processing parameters [soaking time (30-150 min) and parboiling time (2-10 min)]. Its effect on physico-mechanical proprieties viz., length, breadth, height, colour, hardness and rupture energy properties were studied. It was found that the optimized value of soaking time and parboiling time were 148.01 min and 2.68 min, respectively.
