Abstract

Optimal quality retentions of cooked rice packed in retort pouch were simulated by computer using various thicknesses of retort pouch (5 to 24mm) and process temperatures (110 to $150^{\circ}C$). Optimal conditions were chosen by the minimal c-values and maximal thiamine retention when good bacteriological lethality (12D processing) was obtained. From the results of calculations, it were shown that the better quality retentions of high tharmal processing can be obtained below pouch thickness of l0mm and that the thickness of pouch is critical factor at higher processing temperature.

두께가 서로 다른(5${\sim}$24mm) 레토르트 미반에 대하여 여러온도(110-$150^{\circ}C$)에서 최적품질보유가 가능한 고온살균조건을 컴퓨터 simulation에 의하여 구하였다. 최적조건은 12D의 미생물학적 안전성을 유지할 때 최소의 c-값과 최대의 thiamine retention을 갖는 건에 의하여 선정하였다. 계산결과는 고온일수록 시료두께의 영향이 매우 중요함을 보이면서 미반고온살균의 우수한 음질보유는 두께 10mm이하에서 나타난다.
