Optimization of Processing Process for Functional Anchovy Fish Sauce in Addition with Raw Sea Tangle

다시마를 첨가한 기능성 멸치액젓 제조조건 확립

To investigate the quality properties of functional anchovy fish sauce added with raw sea tangle, 2%, 5%, and 10% (w/w) of sea tangle was added to 25% (w/w) salted anchovy and then fermented at $20^{\circ}C$. During fermentation period, the amino nitrogen contents were increased at all groups and the highest contents were at 450 days of fermentation with $11.99{\pm}0.08$, $12.51{\pm}0.08$, and $11.95{\pm}0.08mg/mL$ at 2%, 5%, and 10% addition of raw sea tangle, respectively. After later, the contents were keeping at a similar level. VBN contents were continuously increased until 270 days of fermentation with $208.10{\pm}3.50$, $210.00{\pm}4.10$, $215.15{\pm}1.50mg/100ml$ at 2%, 5%, 10% addition of raw sea tangle, respectively. Alginic acid recovery was gradually increased in fermentation duration, showed the highest concentration at 540 days of fermentation with 67.00, 67.25, 67.90% at 2%, 5% and 10% addition of raw sea tangle, respectively. Dietary fiber recovery was rapidly increased at the beginning of fermentation and then decreased slowly as the fermentation is progressed. The highest recovery was at 30 days with 18.7, 18.6, and 17.9%, and the lowest was at 360 days with 8.7 and 11.1% at 2 and 10% addition of raw sea tangle, respectively, and 450 days with 11.4% at 5% sea tangle. The lowest fucoidan contents were exhibited at 30 days of fermentation with 0.07% at both of 2% and 5% addition, and 90 days with 0.10% at 10% addtion of sea tangle. The highest fucoidan contents were 270 days showing 0.24, 0.25, and 0.23% at 2, 5, and 10% addition, respectively. All groups adding different sea tangle concentration were not significantly different at all properties. However, the newly developed products were sufficient to the standard guideline of Korea Food Drug Adminstration. The best processing process of functional anchovy fish sauce in addition with raw sea tangle is 2% addition of raw sea tangle and fermented more than 450 days. The results obtained in this study indicated that the fish sauce added with sea tangle is superior in taste, functions to traditional fish sauce and could be competitive fishery fermented food.

전통적인 방법을 이용한 기능성 멸치액젓 제조를 위하여 다시마를 농도별로 첨가하고 숙성기간에 따른 멸치액젓 내의 일반성분의 변화는 초기 60일까지 수분함량은 감소하였으며, 이후에는 큰 유의적인 변화가 나타나지 않았으며, 회분, 조지방 함량은 숙성 초기에 다소 변화하지만 일정숙성기간이 지나면 유의적인 변화를 나타내지 않았으며, 조단백질함량은 숙성기간동안 지속적으로 증가하였다. 또한 다시마의 기능성 성분인 알긴산과 식이섬유 함량은 다시마 내에 존재하는 알긴산의 70%, 식이섬유는 50%가 멸치액젓으로 이행되는 것을 확인하였다. 푸코이단과 요오드 함량은 숙성기간동안 지속적으로 증가하고 있으며, 180일 이후에는 유의적인 차이가 없었다. 또한 숙성기간이 450일 이후에는 멸치액젓의 일반성반을 비롯한 기능성 성분의 변화는 유의적인 차이를 나타내지 않고 있다. 따라서 전통적인 방법의 다시마 첨가한 멸치액젓의 의 최적 제조조건은 2% 이상의 생 다시마 첨가와 $20^{\circ}C$에서 450일 이상 숙성기간으로 판단된다. 이와 같이 최적조건으로 제조된 다시마 멸치액젓은 맛과 기능성이 기존 전통 멸치액젓에 비하여 우수하며, 경쟁력을 갖춘 수산발효식품으로 개발될 수 있을 것으로 판단된다.
