The Accelerative Effect on Fermentation of Salted and Fermented Anchovy by Homogenates of Sea Tangle, Laminaria japonica Aresschoug

다시마 마쇄물을 이용한 멸치젓갈의 숙성 촉진

The present study was directed to investigate the accelerative effects of fermentation of salted anchovy on sea tangle homogenates. With the addition of $8\%$ (w/w) sea tangle homogenates(T), there was an increase of amino-N content in both the muscle and juice of salted anchovy during all fermentation periods. It was only in VBN value that there was exhibited the same characteristics as the control batch. Viable cell count in muscle was increased rapidly after 60 days of fermentation, but in juice the content was maximal after 60 days of fermentation. When $8\%$ (w/w) sea tangle homogenates was added, the pH value in muscle and juice were maintained same degree of control until 80 days of fermentation, but showed increase in pH value of muscle and juice more rapidly than the control system after 80 days of fermentation. Then a large percentage of muscle turned to juice after 100 days of fermentation. The degree of fermentation In salted anchovy, when sea tangle homogenates were added, accelerated more than the control batch. Concerning the factors related to the accelerative effects on fermentation of salted anchovy, there was a continuous increase in amino-N content, and it was a sudden change of viable cell count and pH value at a certain point in the fermentation periods.

다시마 마쇄물을 이용하여 멸치젓갈의 숙성촉진에 관하여 연구 검토하였으며 그 결과를 요약하면 다음과 같다. 1. 다시마 마쇄물 $8\%$(w/w) 첨가구(T)는 숙성 80일로부터 pH가 빠른 속도로 증가하였으며 대조구보다 아미노 질소 함량이 다소 낮게 유지되었으나 숙성 120일에 대부분의 육이 액화되어 오히려 숙성이 촉진되는 것으로 나타났다. 2. 육의 숙성 초기 아미노질소의 함량이 높게 유지 되고 액즙에서의 숙성기간에 따른 아미질소 함량의 증가 및 숙성 중 균수와 pH의 상승이 숙성 촉진에 관여하는 것으로 나타났다.
