Abstract

Biological, physical, and chemical hazards in raw manufacturing processes of Saengshik, powdered raw grains and vegetables, were analyzed to identify critical control points (CCPs). In raw materials, total plate and coliform counts ranged 2.82-8.23 and $1.40-6.57\;{\log}_{10}\;CFU/g$, respectively. In final products, total plate counts, except for Lactobacillus spp., were $1.51-7.40\;{\log}_{10}\;CFU/g$. During processing steps, both total plate and coliform counts decreased after washing, whereas no changes were observed after freeze-drying. Physical hazards, such as contents of metal and other contaminants, and chemical hazards, such as moisture content, were assessed. Suggested CCPs for Saengshik were: washing process for controlling microbial contamination, freeze-drying process for controlling moisture content to prevent deterioration and growth of microorganisms, and pulverization process for controlling contamination of foreign substances such as metals. These results will provide guideline to apply HACCP system standards to this product.

생식은 건강 지향적 식생활 양상의 변화로 최근 소비가 급증하고 있으나, 업체의 영세성에 따른 위생관리가 미비하며 제조공정의 표준화가 되어 있지 않아 안전성 문제가 대두되고 있다. 본 연구는 생식의 위생적 생산을 위한 생식 생산 공정의 HACCP 일반모델을 개발을 위해 생식 원료의 세척에서부터 최종제품 포장까지 각 제조공정별로 생물학적, 물리적, 화학적 요인의 위해요인을 분석하고 중요관리점(CCPs)를 설정하고자 하였다. 원료의 세척부터 최종제품 포장까지 각 제조공정별로 생물학적, 물리적, 화학적 요인의 위해요인을 분석하였다. 생식원료의 오염수준은 $2.82-8.23\;{\log}_{10}\;CFU/g$의 일반세균수가 검출되었으며, 또한 $1.40-6.57\;{\log}_{10}\;CFU/g$의 coliforms이 검출되었다. 최종제품 중 일반세균수는 $1.51-7.40\;{\log}_{10}\;CFU/g$이 검출되었다. 제조공정 중 미생물 수 변화는 모든 원료에서 공정별로 유사한 패턴을 보여 주었는데 세척과 동결건조공정에서 일반세균수와 대장균군은 감소하였다. 물리적 요인인 이물 혼입과 화학적 요인인 수분함량의 변화가 위해 요인으로 분석되었다. 생식의 제조공정 중 CCP는 미생물 감소를 위한 세척 단계, 수분 관리를 위한 건조단계, 그리고 금속 등 이물질의 혼입단계로 설정되었다.
