Abstract

As a method of utilization of sardine, sardinops melanosticta, proper processing conditions for a low salt fermented sardine were investigated. And changes of chemical components during fermentation and the effects of additives to improve the quality of the product were also discussed. A low salt fermented sardine was prepared with 8 or $10\%$ of salt and various contents of additives such as lactic acid, sorbitol, glycerin and ethanol as preservatives and flavor enhancers, and fermented for 80 days at $29\pm3^{\circ}C$. Judging from the changes in pH, amino-nitrogen and volatile basic nitrogen during fermentation of low salted sardine and the organoleptic evaluation on their flavor, the products of sardine meat containing 8 or $10\%$ of table salt, $0.5\%$ of lactic acid, $6\%$ of sorbitol and $6\%$ of ethanol as additives were most desirable when fermented for 60 days.

정어리를 효율적으로 이용하기 위한 하나의 방안으로서, 식염농도가 낮은 정어리젓의 가공조건을 설정하고자 젖산, sorbitol, glycerin, 에틸알코올을 첨가하여 숙성 중의 pH, 휘발성염기질소 등의 변화를 관능검사와 더불어 실험한 결과 정어리젓의 최적가공조건은 정어리육에 대하여 젓산 $0.5\%$, sorbitol $6\%$, 에틸알코올 $6\%$를 젓담금할 때 첨가하여 60일간 숙성시키는 것이라는 결론을 얻었다.
