Comparison of Sorption Characteristics of Several Soybean Varieties

Abstract
|
|
|
Seven varieties of soybeans(Paldal, Danyeob, Jangbaek, Baegun, Jangyeob and 2 cultivars of Local 1 and Local 2) were investigated to compare the sorption characteristics during storage of various relative humilities. The sorption isotherm curve determined at RH range of 33¡92 % and 4 ¡É and 25 ¡É showed that moisture contents of soybeans was higher at 4 ¡É than those values at 25 ¡É for overall water activities of 0.33¡0.92. The Paldal was the highest moisture content at 4 ¡É while that value of Baegun was the highest at 25 ¡É. The change in moisture content with storage time was expressed by log(dw/dt)=b log(t)£«log a and the value of (dw/dt)¡¿10©øwas decreased logarithmically. The Paldal was comparatively the highest initial absorption rate and the value of -b in seven varieties decreased as the relative humidity increased from 33 % to 92 %.
