초록
본 시험은 L. monocytogenes KCTC 3443을 액체 배양한 후, 일반적인 열처리 및 마이크로파를 조사함으로써 가열효과에 의한 균의 불활성효과를 파악하는데 그 목적을 두었다. 2,450MHz, microwave oven을 통한 마이크로파의 온도 제어는 시료가 각각의 시험 설정 온도에 도달한 후 30분간 온도를 유지할 수 있도록 컴퓨터에 의해 제어되었으며, 온도의 편차는
The purpose of this study was to determine the thermal inactivation of L. monocytogenes KCTC3443 in liquid culture heated in the controlled microwave system and in the conventional heating method. Furthermore, we have carried out a comparative study on the thermal and nonthermal microwave effects on microorganisms, pasteurized using a controlled microwave energy specially designed apparatuses and a water bath. For the automatic temperature control during microwave heating, the real time data acquisition and computation system is designed with BASIC routine. The automatic temperature control system used in the experiments perform relatively stable control at the experiment temperature of 55, 65,
