Studies on the Preparation of Improved Soysauce Kojis
메주제조개선(製造改善)에 관(關)한 연구(硏究)
Abstract
In order to determine proper ratio of wheat to soybean of soysauce koji material for Korean people's taste, sensory evaluation for the soysauces made from soysauce kojis with various above-mentioned ratio and analysis of chemical components through the brewing period of six months were carried out. The results obtained were summarized as follows: 1. The specific gravity of all the soysauces increased gradually as the time passed and had maximum values in two months with nearly constant values thereafter. Concerning soybean/wheat-ratio, generally, the higher soybean/wheat-ratio, the lower specific gravity was observed but when this ratio was higher than 10 : 6, the gravity was on the similar levels. 2. The solid material in all the soysauces increased in the earlier stage and there were no significant differences among the treatments but soysauces without wheat had a little low content. 3. The lesser amount of wheat as raw material was, the higher contents of total nitrogen were and the contents of total nitrogen in the every ratio of raw material increased parallely as the mash ages. 4. The amino-nitrogen levels were found to have the simllar tendency to total nitroghen levels. 5. The reducing sugar content was higher in the soysauces with more-wheat and increased rapidly up to the maximum level in two months and then the higher wheat/soybean-ratio was, the slower decrease of the sugar content was observed. 6. The maximum total acidity was observed in the soysauces with 10; 4-6 (soybean/wheat-ratio) and increased similary in all the soysauces throughout the period. 7. According to the sensory evaluation, the short (2-3 months) fermented soysauces showed best taste when soybean/wheat-ratio was 10 : 8 and 10 : 6 if diluted, but in long (4-6 months) fermented soysauces it was 10 : 6 and 10 : 4 if diluted.
콩과 밀의 배합비(配合比)를 달리하여 제조(製造)한 7종(種)의 개량(改良)메주를 사용(使用)하여 담근 간장의 6개월간(個月間)의 담금기간중(期間中)의 간장의 제성분변화(諸成分變化)를 조사(調査)하는 동시(同時)에 제조(製造)간장 원액(原液)및 10배(倍) 희석액(稀釋液)에 대(對)하여 20명(名)의 심사원(審査員)이 식미시험(食味試驗)을 하여 다음과 같은 결과(結果)를 얻었다. 1) 비중(比重)은 경시적(經時的)으로 약간 증가(增加)되지만 2개월후(個月後) 부터는 거의 일정치(一定値)를 보이고 일반적(一般的)으로 밀의 배합비(配合比)가 많을수록 착간 높으나 콩에 대(對)한 밀의 배합비(配合比)가 10 : 6 이상(以上)에서는 비슷한 경향(傾向)을 보였다. 2) 엑스분(分)은 초기(初期)에는 증가(增加)되었으나 후기(後期)에는 거의 일정치(一定値)를 나타내고 가료배합구간(價料配合區間)에도 뚜렸한 경향(傾向)을 볼 수 없었다. 3) 총질소(總窒素)는 밀의 배합비(配合比)가 많을수록 낮고 모든 배합구(配合區)에서다 3개월(個月)까지는 완만한 증가(增加)를 보이다가 3개월후(個月後) 부터는 거의 일정치(一定値)를 보였다. 4) Amino 태질소(態窒素)는 처음 1개월(個月)까지는 급격한 증가(增加)를 보이다가 그 후(後)
