Study on Absorption of Zein to Ethanol

Abstract

Abstract: Zein was prepared by organic solvent extraction.The change of ethanol concentration was measured by alcoholmeter before and after absorption of zein.The single factor analysis was adapted to determining the optiomal conditions such as pH,temperature,ethanol concentration and ratio of liquid to solid.The results showed that there is the maximum ethanol adsorption under the conditions of ethanol concentration 30%,ratio of liquid to solid 1:10,20 ℃ and pH 6.The results lay a foundation for using zein to reduce alcohol concentration.

Key words: zein, ethanol absorption
