鸡蛋粉等温吸附特性研究

Studies on the Adsorption Isotherms of Egg Powder

摘要:

研究了冷冻干燥鸡蛋全蛋粉、蛋白粉和蛋黄粉在10 ℃、20 ℃、30 ℃、40 ℃下的等温吸附和解吸特性及滞后现象，建立3种蛋粉等温吸附曲线的回归方程，并计算出三种干燥蛋粉的BET单层值。

Abstract:

The adsorption, desorption and hysteresis properties of the freeze drying All-egg powder, Albumen powder and vitellus powder at 10 ℃, 20 ℃, 30 ℃ and 40 ℃ were studied. The Regression equation of absorption isotherms curves of the three kinds of egg powders was obtained and the BET surface values of these egg powders were also achieved.
