Summary
Soybeans, divided soybeans and dust were selected from those imported from the U.S., were stored for year under different temperature and humidity conditions [20 centigrade (33, 43, 56, 66, 79, 94% R.H.) and 30 centigrade (32, 43, 52, 59, 78, 92 % R.H.)]. The surface characteristics, that is the solidity of the dust and the moldy area of soybeans, were observed. Their moisture content was measured.HomePage
The results of the analysis showed the existence of a strong correlation between the grade of the moldy area and the moisture content of soybeans. Using the method of multiple linear regression, the formula which can evaluate the change in the moisture content of soybeans during one year at any temperature and humidity was able to be obtained.
The effect of temperaturd, humidity and the length of the storage time for the value of the moisture content and the grade of the moldy area of soybeans, were analyzed using the method of variance analysis. The constant value of the Henderson(s equation was obtained from the experimental value of the moisture content, in which soybeans were stored for 10 months.
