초록

본 연구에서는 식품접객업소에서 시중 판매되는 더치커피의 미생물 오염도를 조사하여 유형에 따른 차이를 살펴 보고자 하였다. 경기도 내 커피전문점에서 유통되는 더치커피 70건을 대상으로 위생지표균, 식중독균, 진균류 오염도를 조사하였으며 추출방법에 따른 일반세균과 진균류의 오염도를 비교하였다. 일반세균수는 0.74-6.21 log CFU/mL 범위로 검출되었으며 식품 유형에 따른 평균 검출량은 식품접객업소 조리식품(3.04 log CFU/mL)이 액상커피(2.08 log CFU/mL)보다 높게 나타났다. 액상커피는 검출된 6건 중 3건이 세균수 기준을 초과하여 부적합이었다. 식중독 원인균은 70건 모두 불검출이었다. 진균수는 0.70-4.00 log CFU/mL 범위로 검출되었으며 식품유형에 따른 차이는 없었다. 추출방법에 따른 미생물 오염도는 원두 혼합 여부와 추출 시간에 따라 비교하였으며, 일반세균수와 진균수 모두 유의적인 차이는 없었다(P>0.05). 시중 유통되는 더치커피는 일반세균과 진균류에 대한 오염도가 높으므로 위생적인 관리와 적절한 온도 유지를 통해 미생물 오염을 줄이는 것이 중요하며 안전성 확보를 위해 지속적인 모니터링이 필요할 것으로 생각된다.

This study aimed to investigate microbial contamination of Dutch coffee in Gyeonggi province, South Korea. A total of 70 different Dutch coffee were purchased from an offline market (food service business operator). Two types of coffee were considered: "coffee made from food service business operator" and "coffee made from food manufacturer." The levels of total aerobic bacteria were 0.74-6.21 log CFU/mL in 15 samples and fungi were 0.70-4.00 log CFU/mL in 21 samples. Total aerobic bacteria was detected at higher levels in "coffee made from food service business operator" than in "coffee made from food manufacturer," and the difference was not significant. Three samples in "coffee made from food manufacturer" exceeded the standard for total aerobic bacteria. Escherichia coli, Coliform, and 12 types of foodborne bacteria were not detected in all samples. The extraction method detected no difference in cell counts of total aerobic bacteria and fungi. Therefore, to reduce microbial contamination of Dutch coffee, managing hygiene while maintaining the refrigeration temperature from the bean management stage to the sale process is crucial.
