Abstract

This study was conducted to investigate the antibacterial activities and sensory properties of a sauce containing tea extract and garlic vineger against raw fish. The sauce was evaluated antibacterial activity against Vibrio parahaemolyticus and Vibrio vulnificus which is considered as one of the major food borne pathogens. As a result, the sauce inhibited the growth of V. parahaemolyticus and V. vulnificus distinctly. In addition, the sauce with soy sauce and Kochujang showed the restricted growth of Vibrio parahaemolyticus and Vibrio vulnificus in sliced raw flatfish. Sensory evaluations were measured by 7-point hedonic scale using sliced raw flatfish with the sauce mixed with Kochujang and soy sauce. The score of texture in the sauce with Kochujang was significantly higher than that of regular Chokochujang (p<0.05). Moreover, total preference including appearance, texture, aroma and taste were significantly higher in the sauce with soy sauce than those of regular soy sauce (p<0.05). Consequently, the soy sauce with tea extract and garlic vinegar may enhance the satisfaction of consumer and antimicrobial activity that against V. parahaemolyticus and V. vulnificus, resulting in potential reduction the outbreaks of food borne pathogens.

본 연구는 여름철 식중독의 주원인균으로 알려져 있는 Vibrio parahaemolyticus와 Vibrio vulnificus를 대상으로 마늘식초와 차 추출물을 이용해 제조한 생선회용 소스의 항균활성을 평가하고, 실제 생선회에 적용 시켰을 때의 관능특성을 평가하기 위해 수행되었다. 제작한 생선회용 소스는 시판 간장, 고추장과 비교했을 때 V. parahaemolyticus와 V. vulnificus에 대해 생육저해환을 생성하며 항균활성을 지니고 있음을 보여주었으며, 두 균주의 생육을 저해하였다. 또한 생선회에서도 생선회용 소스가 살균효과를 나타내는지 확인하기 위해 고추장-생선회용 소스, 간장-생선회용 소스로 제작하여 광어회에 적용시켰을 때에도 두 균주의 생육을 뚜렷하게 저해하였음을 보여주었다. 생선회용 소스를 실생활에서 회를 섭취할 때 쉽게 수용할 수 있을지 알아보기 위해 관능평가를 실시한 결과, 고추장-생선회용 소스 및 간장-생선회용 소스가 시판 고추장 및 간장에 비해 전체적으로 높은 점수를 얻음으로써 선호도가 높은 경향을 보였다. 이 중 고추장-생선회용 소스는 조직감 측면에서 유의적으로 우수하다는 평가를 받았으며, 간장-생선회용 소스는 외관, 조직감, 향미, 맛, 종합 기호도 등 모든 측면에서 유의적으로 우수한 것으로 나타났다. 이상의 결과로부터 마늘식초와 차추출물로 제작한 생선회용 소스는 V. parahaemolyticus와 V. vulnificus에 대해 효과적인 살균력을 갖는 것으로 확인되었으며, 간장과 고추장에 활용할 경우 그 항균활성으로 인해 생선회 섭취로 인한 식중독을 예방할 뿐만 아니라 소비자의 만족도를 향상시켜 여름철 생선회 소비를 촉진시킬 수 있을 것이라 판단된다. 더 나아가 여러 가지 소스에 적용할 수 있도록 기능성평가 및 관능평가를 실시하는 등 보완된 연구를 계속한다면 다양한 소스에의 활용이 가능할 것으로 판단된다.
