摘要:

以玉米醇溶蛋白为原料,分析和比较冷冻干燥、真空干燥和热风干燥对玉米醇溶蛋白的影响。实验结果表明,冷冻干燥样品的色泽相对较浅,吸油性、乳化性和乳化稳定性略高于真空干燥样品和热风干燥样品;3 种样品的蛋白质含量、溶解性和持水力无明显差别;冷冻干燥对玉米醇溶蛋白的性质影响较小。

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
