Quality Evaluation of Juanbyeo as Aseptic-packaged Cooked Rice

Nongshim Co. Ltd.Abstract The objective of this study was to evaluate several varieties of aseptic-packaged cooked rice includingJuanbyeo. Quality evaluations, such as by amylose, setback, toyo values and amylograms, were significantly higher in theJuanbyeo as compared to other samples. In addition, the Juanbyeo aseptic-packeged cooked rice showed significantlyhigher palatability characteristics and had a greater water absorption ratio than the other samples. For cold cooked rice,the relationship between palatability and texture was significantly high (p<0.01). Ilpumbyeo showed high scores for tasteas a hot cooked rice, but as a cold cooked rice taste scores were lower than other samples. In the case of Juanbyeo coldcooked rice flavor was improved. When the Juanbyeo aseptic-packaged cooked rice was reheated in a microwave oven,it had better palatability than other varieties. Thus, the results of this study suggested that Juanbyeo can be effectivelyutilized as aseptic-packaged cooked rice.Key words: rice, aseptic-packaged cooked rice, quality, Juanbyeo
