Evaluation of Thermal Processes for Canned Marine Products (1) Canned Boiled Sea-mussel in Brine and Canned Smoked Sea-mussel in Oil

수산물통조림의 살균조건에 관한 연구(1) 홍합 보일드 통조림 및 홍합 훈제 기름담금 통조림

The present studies were conducted to evaluate the sterilizing efficiency of the thermal processes for the canned sea-mussel products, such as canned boiled sea-mussel in brine (packed into No. 1 flat can) and canned smoked sea-mussel in oil (packed into No. 3B square can), with the purpose of deciding the adequacy of the processes. Heat penetration was tested three times with three cans at a time for each canned product. The tip of the applicator was fixed on the position a little below the geometrical center of the can. The test cans were placed in the middle layer of the basket in which the same canned products were loaded with, and the test cans were arranged to the front, the middle and the rear in the retort. The heat penetration curve of the canned boiled sea-mussel in brine showed a broken logarithmic heating curve while that of the canned smoked sea-mussel in oil showed a simple logarithmic heating curve. The calculated $F_0$ value for the canned boiled sea-mussel in brine was 25.33 and the canned smoked sea-mussel in oil was 13.84. Additionally, the nomographs represents the relationship between $F_0$ values and B values(process time including $42\%$ of come-up time) for the canned sea-mussel products were constructed.

수산물통조림의 살균조건을 검토하기 위한 연구의 일환으로 홍합 보일드 통조림(평1호부) 및 홍합 훈제 기름담금 통조림(각 3호 B관)에 대하여 업계에서 적용하고 있는 살균조건하에서 열전달치를 측정하고 이로부터 $F_0$값을 산출하여 검토하였다. 홍합 보일드 통조림 (평 1 호부)의 $F_0$ 값은 25.33이었고, 홍합 훈제 기름담금 통조림(각3호 B부)의 $P_0$값은 13.84로, 모두 Clostridium botulinum A 형균의 치사치인 $F_0=4.03$을 충족시키고도 남는 높은 살균강도였다. 특히, 홍합 보일드 통조림(평 1 호관)은 홍합 훈제 기를담금 통조림(각 3호 B관)에 비하여 훨씬 강한 살균강도로 처리하고 있음을 알 수 있었다. 또한, 동일제품에 있어서 살균온도 및 살균시간이 변동하는데 따라서 $F_0$값이 어떻게 변화하는가를 알기 위하여 살균온도별로 $F_0$값에 따른 B값을 산출하여 그 nomograh를 작성하였다.
