조리조건이 익혀진 콩의 품질에 미치는 영향을 알아보고저 인스트론을 사용하여 텍스쳐의 변화를 측정하였고 puncture force와 shear force의 측정결과를 사용하여 조리온도를 달리하였을 때의 cooking kinetics를 검토하였다. 관능검사에 의해 알맞게 익혀졌을 때 황색콩의 puncture force는 0.15kg, shear force는 1.2kg/g-soybean으로 나타났으며 활성화에너지 값은 각각 14,540, 21,374 cal/g-mole이었고 z값은 $42.1,;37.4^{circ}C$이었다. 이러한 결과로 조리된 콩의 텍스쳐는 침지와 조리 조건에 따라 크게 영향받음을 알 수 있었다.
Soaking of soybeans and the subsequent effect on cooking kinetics were investigated by the means of puncture test and shear press with Instron universal testing machine. Soaked soybeans were water cooked at temperatures of $90{sim}135^{circ}C$ adjusted with oil bath. Instron puncture force of 0.15kg and shear force of 1.2kg/g-soybean were appeared as the eating soft texture by sensory evaluation. Softening activation energies of yellow soybeans for puncture and shear force were 14,540cal/g-mole and 21,374cal/g-mole. z-values were calculated as $42.1^{circ}C$ and $37.4^{circ}C$, respectively.
