| Research Abstract |
Adsorption-desorption isotherms of kidney beans (Taishokintoki) and azuki beans were established at temperature of 20ﾟC,and relative humidities ranging from 12.4 to 80.6%. As the desorption moisture contents were higher than the adsorption values, the effect of hysteresis was showed in both beans. The equilibration periods under static condition were 60 to 70days for kidney beans, and 80 to 100days for azuki beans.
Hard and sound kernels of azuki beans were separated by specific gravity using saturated NaCl solution. The water absorbing ability of hard kernels at 20ﾟC for 24 hrs was significantly lower tan sound kernels. Since the water is mainly absorbed at a strophiole in azuki beans, scanning electron micrographs of a strophiole and surrounding areas were taken. Because the remarkable deference in the structure of strophiole were recognized between hard and sound kernels, water absorption of azuki beans might be affected by its change.
Near inflared spectra of hard and sound kernels were obtained from 400 to 2200nm at 2nm intervals using sample transport module, respectively. Second derivative spectra from 1134 to 2200nm were analyzed to separate hard and sound kernels using IQ square software. As the result, it was possible to separate of hard and sound kernels using near inflared analysis.
