Abstract

The aim of this research was to apply a HACCP system (Hazard Analysis Critical Control Point) to fermented milk. The main ingredients of fermented milk, work facilities and workers were obtained from a company named YD, which is located in Seobuk-gu, Cheonan-si between November 5 2013 to April 13, 2014. A manufacturing process chart was prepared by referring to the manufacturing process of fermented milk manufacturers in common. The manufacturing process chart was made with raw materials; Raw milk, High Fructose Corn Syrup, Oligosaccharides, Lactic Acid bacteria and Subsidiary ingredients, Warehousing of packaging materials, Storage, Input, Preheating, Mixing, Homogeneity, Sterilization, Precooling, Culture, Filtration, In packaging, Out packaging, Storage, and Consignment, as listed Table 1. The results of the microbiological hazard analysis on the raw materials was safe after sterilization($90^{\circ}C{\pm}5^{\circ}C$, $35{\pm}3min.$) On the other hand,a microorganism test of an environment and workers suggested that the microbiological hazard should be reduced through systematic cleaning and disinfection accompanied by improved personal hygiene based on hygienic education on workers and the management of microorganisms in air.

본 연구는 발효유류의 HACCP(Hazard Analysis Critical Control Point)시스템 적용을 위한 목적으로 하였다. 발효유류의 주원료, 작업장 시설과 작업자 등에 대하여, 2013년 11월 5일~2014년 4월 13일까지 충청남도 천안시 서북구 소재에 있는 YD 업체에서 제공받았다. 제조공정도는 일반적인 발효유류 제조업체의 제조공정을 참고로 작성하였다. 제조공정도는 원료(원유, 액상과당, 올리고당, 유산균), 부재료, 포장재의 입고, 보관, 투입, 예열, 혼합, 균질, 살균, 예냉, 배양, 냉각, 여과, 내포장, 외포장, 보관 및 출하공정으로 Fig. 1과 같이 작성하였다. 원료의 미생물학적위해요소 분석결과는 Table 1과 같다. 본 연구결과 발효유의 원재료와 살균($90^{\circ}C{\pm}5^{\circ}C$에서 $35{\pm}3$분) 후에는 위해미생물검사 결과는 안전하나 제조환경과 작업자의 미생물검사 결과 체계적인 세척 및 소독을 실시하여 미생물학적 위해를 감소시키고, 작업자 위생교육 등을 통하여 개인위생개념 향상과 작업장 내 공기중의 미생물 관리가 함께 이루어져야 할 것으로 여겨진다.
