This study was carried out to investigate the optimum mashing and maturing conditions for Korean traditional Kanjang(soy sauce) production and to reduce the fermentation period. The effects of maturing time of soy sauce mash, maturing temperature, salt concentration and the ratio of Meju to salt brine on the quality of Kanjang(total nitrogen, pH and color) were examined. Soy sauce pigments and about 90% of N constituents contained in soybean Meju(Koji) in soy sauce mash were degraded and solubilized into liquid portion (soy sauce) of the mash within five days of maturing at 30℃ with the mashing ratio(weight/volume) of 1 : 4 of soybean(as raw soybean) to 20% salt brine. No remarkable effects of soy sauce maturing temperature in the range of 5℃∼30℃ on the digestion and solubilization of N components and pigment extraction during five days of soy sauce mash maturing were observed. Optimum mashing salt brine concentration for the digestion and solubilization of N components and pigment extraction during soy sauce maturing at 30℃ were observed to be in the range of 15∼20%. The suitable mashing ratio of Meju to salt brine (wt./vol.) to match N content of the standards of identity of Korean traditional Kanjang(soy sauce) was found to be below 1 : 5.

재래식 간장의 맛을 개선하기 위하여 대두 자숙액, 당 및 젖산균과 효모를 접종하고 자연조건에서 발효시키면서 젖산발효와 알코올발효 효과를 조사하였다. 젖산균과 효모 접종구에서 젖산의 생성량이 2.91%로 가장 높았고, 그 다음이 간장 덧에 당만을 첨가한 구에서 2.38%, 대두 자숙액 만을 첨가한 대조구에서 2.05%로 나타나 모든구의 간장에서 젖산발효의 효과가 있었으나, 알코올은 모든 처리구에서 소량 검출되어 젖산균에 의해 생성된 초산 때문에 효모의 생육이 저해되어서 알코올발효 효과는 없는 것으로 나타났다. 기호도에서도 젖산균과 효모 접종구와 당 첨가구가 우수하였다. In order to evaluate the effects of addition of soybean boiling waste liquor (SBWL) and sugar and inoculation of the lactic acid bacteria and yeast starter culture in Korean traditional kanjang mash, three types of kanjang were prepared in a clay pot of 100 l volume and compared the characteristics of lactic acid fermentation. The mashing compositions of the types of kanjang were as follows: (1) control treatment mash was prepared with meju : 20% salt solution (1:4) and SBWL, (2) kanjang mash with 3.5% added sugar to the control type mash and (3) kanjang mash with 3.5% added sugar and inoculation of the lactic acid bacteria and yeast starter culture 35 days after mashing to the control type mash. (1), (2) and (3) of kanjang mash were found to be effective in increasing the lactic acid content and improving the organoleptic characteristics of kanjang. But the effect of yeast starter culture was not clear because osmophilic yeasts were inhibited by metabolite(acetic acid) produced by lactic acid bacteria. The lactic acid content of (1), (2) and (3) kanjang was 2.05, 2.38 and 2.91% respectively in 90 day-matured kanjang.

전통간장의 맛과 품질을 개선하기 위하여 간장제조시 탄수화물과 효소원으로써 맥아의 첨가법에 대하여 연구하였다. 전통메주(대조)와 메주제조시 맥아를 첨가하여 만든 메주 및 간장 담금시 전통메주에 맥아를 첨가하여 각각 간장을 담금한 후 150일간의 숙성기간동안 간장의 성분 변화를 조사하고 숙성간장의 식미검사를 실시하였다. 메주 제조시 맥아를 첨가하여 만든 메주로 담근 간장은 대조구인 전통 콩메주로 담근 간장에 비하여 간장 담금 초기부터 150일간의 숙성을 마칠 때까지 총질소, TCA가용성 질소, 색도, 순추출물 및 젖산함량이 높았으며 맥아첨가량이 더 많은 메주로 만든 간장에서 이들 성분함량이 더 높았다. 그러나 간장 담금 할 때 간장덧에 맥아를 첨가하였을 때는 포도당을 제외하고는 전통메주로 담금한 대조구 간장보다 오히려 성분함량이 낮았다. 식미검사에서도 메주제조시 맥아를 30% 첨가한 간장이 모든 기호도 특성에서 가장 높은 점수를 얻었고 종합적 기호도 점수도 7.56점으로서 전통간장(대조구)보다 5% 수준에서 유의적으로 식미가 우수함을 보여주었다. Methods of adding barley malt as source of carbohydrates and enzymes in the production of kanjang in order to improve it's tastes and qualities were investigated. Soybean meju, soybean-malt meju and soybean meju cummalt was mashed with 20% salt brine in the ratio of 1:3 respectively, matured and analyzed the chemical compositions of the soy sauce mash samples for 150 days of maturing. Organoleptic evaluations for the matured soy sauce samples were done. The higher total nitrogen, TCA soluble nitrogen, O.D. at 500 nm, pure extract and lactic acid content could be observed with the soy sauce mash made of soybean-malt meju than those of contrast one from the beginning of the mashing throughout to the whole maturing period of 150 days. The higher the content of malt in the soybean-malt meju, the higher those content in the mash. But the lower content of those compositions in the soy sauce mash made of soybean meju cum malt than those in the contrast was found. The highest scores in all the sensory characteristics including 7.56 points, which were significantly different from that of contrast soy sauce at 5% level, in overall palatability were obtained by the soy sauce made of soybean-malt meju added with 30% malt in the organoleptic evaluations.
