Industrial irradiation of green mungbean and sensory acceptability evaluation

To determine the efficiency of gamma irradiator, Model JS-8900, IR-155, 50-kg commercial packages of green mungbean (Phaseolus aureus) were used. The optimum product throughput was 5,400 kg in 1 h 11.91 min. To improve product loading efficiency, 1-kg packages of green mung-bean were used and the optimum product throughput was 8,640 kg in 1 h 47.4 min. Green mungbean irradiated at 0, 0.5, 0.9 and 1.0 kGy were used for sensory acceptability evaluation. The panel accepted the color, taste and texture of steamed-green mungbean, regardless of radiation dose and accepted the odor of nonirradiated steamed-green mungbean. For raw-green mungbean, the panel accepted the color and odor of raw-green mungbean irradiated at 0, 0.5 and 1.0 kGy
