본 연구는 한국시장에 저장중인 수출 돈육과 일본시장에 실제 수출이 완료되어 유통중인 한국산 진공포장 냉장돈육에 대한 위생성을 일본 후생성에서 요구하는 수입식육의 유통기한 기준안에 준해 조사하여 한국산 돈육의 위생성과 유통기한을 파악하고자 실시하였다. 공시시료는 비교적 오랜 기간 동안 일본에 냉장육을 공급해 주고 있는 4개 회사의 제품으로 우리 나라내 조사에서는 레귤러 등심과 뒷다리살을 이용하였으며, 일본 현지에서는 레귤러 등심만을 이용하였다. 국

This study was carried out to examine the quality of Korean pork regular loins and hams which m exported in Japanese market. The samples were stored at 01(A, B companies) and 21(C, D companies). In analysis of Korean pork exported to Japanese market, the pork of A and D companies showed below 106/CFU/ of total aerobic bacteria at 40 days storage and panels felt off-flavor after 40 days. Therefore the edible period will be 40 days through the analysis of microbe and sensory test in porks of A and D companies. The porks of B and C companies showed over 106/CFU/ of total aerobic bacteria at 50 days storage and panels couldn't feel off-flavor in sensory test after 50 days. Therefore the edible period will be 50 days through the analysis of microbe and sensory test in porks of B and C companies. As the results, shelf-life of A and D companies will be 32 days and B and C companies will be 40 days from edible period by a factor of 0.8. In analysis of stored pork for export in Korean market, the porks of A and B companies showed over 106/CFU/ at 40 days storage and C and D companies did over 106/CFU/ at 30 days storage in analysis of microbe. The pork of A and D companies showed 10CFU/ but B and C companies did 105/CFU/ at 50 days in coliform count. Therefore shelf-life of the pork of A company was logest and the next were B and C, but shelf-life of the pork of D company was 20 days, therefore it was even shorter than the others.
