Abstract

This study was carried out to investigate the effectiveness of Leuconostoc mesenteroides isolated from octopus baechu kimchi as a potential starter for seafood kimchi. L. mesenteroides is lactic acid bacterium currently used as a starter for kimchi production. We selected the most effective L. mesenteroides strain from the 7 strains isolated from octopus baechu kimchi and, based on biochemical properties and 16S rRNA sequencing, identified the selected strain as L. mesenteroides SK-1. The SK-1 strain exhibited acid-tolerance, good survival capacity, and excellent dextran productivity. We investigated the effects the SK-1 of starter on seafood kimchi fermentation. Octopus baechu kimchi was fermented with L. mesenteroides SK-1 at $4^{\circ}C$ for 35 d. The decrease in pH and increase in acidity in octopus baechu kimchi fermented with the SK-1 starter occurred more quickly than that in the control kimchi indicating that. Octopus baechu kimchi with SK-1 starter has a relatively slow rate of increase in lactic acid production. As a result, octopus baechu kimchi prepared with L. mesenteroides SK-1 can be maintained at a suitable ripening degree over an extended period of time compared to that of the control kimchi, Moreover, the octopus baechu kimchi started with L. mesenteroides SK-1 has excellent sensory properties, including a refreshing taste, and a weak sour odor.

본 연구에서는 수산물김치의 시원한 맛과 풍미를 오랫동안 유지시켜 줄 수 있는 수산물김치 전용 유산균 스타터를 찾고자 하였다. 문어 배추김치로부터 내산성 및 덱스트란 생성능이 우수한 균주 SK-1을 선발하고 동정한 결과 L. mesneteriodes와 99% 상동성을 나타내어 L. mesneteriodes SK-1으로 명명하였다. 수산물김치 스타터로서 L. mesneteriodes SK-1 균주의 활용가능성을 알아보기 위해, pH, 산도, 젖산 생성량 및 Lesuconostoc sp. 균주의 변화를 L. mesneteriodes KCTC 13302 및 L. mesneteriodes KCTC 3505 균주와 비교하였다. L. mesneteriodes SK-1 균주 배양액을 스타터로서 첨가하여 제조한 문어 배추김치의 pH는 숙성 21일 이후부터는 4.56에 도달한 이후 계속 유지되는 양상을 보인 반면 L. mesneteriodes KCTC 13302 및 KCTC 3505 배양액을 첨가한 문어 배추김치는 숙성 21일 이후부터 pH가 감소하는 경향을 나타내었다. 또한, L. mesneteriodes SK-1 균주를 첨가한 문어 배추김치의 산도는 $4^{\circ}C$에서 숙성 28일째 적정 산도 0.65%에 도달한 반면에 L. mesneteriodes KCTC 13302 및 KCTC 3505 균주를 첨가한 문어 배추김치는 각각 숙성 17일 및 21일 경에 적정 숙성 산도인 0.65%에 도달하였다. 또한, L. mesneteriodes SK-1 균주를 첨가한 문어 배추김치는 숙성 21일째 젖산 생성량이 0.72 mg/mL를 나타낸 이후 숙성 28일 및 35일째에도 젖산 생성량은 0.76 mg/mL 및 0.79 mg/mL로 일정한 값을 나타내었으나, L. mesneteriodes KCTC 13302 및 KCTC 3505 균주를 첨가한 문어 배추김치는 숙성 28일째에 젖산생성량이 급속히 증가하여 각각 1.12 mg/mL 및 1.15 mg/mL을 나타내었다. 한편, L. mesneteriodes SK-1 균주를 첨가한 문어 배추김치는 숙성 14일째 이후부터 Leuconostoc sp. 균수가 $10^8CFU/mL$ 이상의 수준을 일정하게 유지되는 결과를 나타내었고 관능평가 결과에서도 SK-1 균주를 첨가한 김치가 KCTC 13302 및 KCTC 3505 균주를 첨가한 김치보다도 신맛은 적고 시원한 맛, 탄산미 등의 종합적인 맛 평가에서 유의적으로 높은 점수를 받았다. 이상의 결과로부터 L. mesneteriodes SK-1 균주를 첨가하여 제조한 수산물김치는 산도 및 젖산생성량이 낮아 적정 숙성도가 오래 유지됨으로서 관능적으로도 우수할 뿐만 아니라 장기간 저장 및 유통이 가능한 수산물 김치 전용 스타터로서의 활용가능성이 기대되었다.
