摘要: A method has been developed to measure the texture of raw and soaked cowpeas (Vigna unguicuiata) using a wedge-type blade mounted in an Instron testing machine cut across cotyledons. It was found that soaking water prior cooking produced softer bean decrease hardness proportional time. Texture cooked beans could be predicted from corresponding bean. The influence temperature time on studied shear-compression cell - Test System Ottawa Measuring with wire extrusion grid. rate relative followed first order kinetics. Scanning electron microscopy used study changes microstructure during process. major effect observed breakdown middle lamella; walls remained intact.
