Abstract

In this paper, the extraction mechanism of redish yellow pigment from the husk of sorghum seed is discussed and an empirical equation has been derived. It is as follows; F total =[(In 1.0333t0.0196)(0.3719 S/1+0.3219 S)T+0.3565] $\times$e-(6$\times$10-6c+4.9$\times$10-4)(C-60)$^2$where F total : total amount of sorghum pigment extracted from the husk of sorghum seed t : extraction time T : extraction temperature S : volume of solvent C : concentration of ethyl alcohol
