Abstract

Abstract:

In this study, zein was used as the material to investigate effects of lyophilization, vacuum drying and hot-air drying on its properties. Results indicated that the color of the sample exhibited a little light through lyophilization. However, oilabsorption capability, emulsifying property and emulsifying stability of the sample treated with lyophilization were higher than those of samples through vacuum drying and hot-air drying. Protein content, solubility and water-holding capacity of samples through three drying methods did not exhibit obvious difference. Therefore, lyophilization treatment has less effect on properties of zein.

Key words: zein, lyophilization, vacuum drying, hot-air drying
