Abstract
Geep-Jang, a kind of soybean paste, was made from vegetables such as egg-plant, green cucumber and green red pepper besides grains, which was fermented at $55{\sim}60^{\circ}C$ incubator or room temperature for a week. In order to determine the effect of cellulolytic enzymes addition on the Geep-Jang processing, samples were taken by 0, 24, 48, 72, 96, 120, and 144 hours interval after first stage, chemical composition were measured and its results obtained as follows: 1. Reducing sugar was rapidly increased from twenty to forty hours after first stage. 2. Large contents of reducing sugar at G-5 group might originated from the much quantity of carbohydrate sources and speed up the decomposition of raw materials by cellulolytic enzymes. 3. The different content of reducing sugars between G-1 and G-3 group should stemed from the addition of enzymes solution and it's differences were very remarkable id the case of classic soybean koji power 4. The contents of amino-nitrogen was generally more increased than the classic one(G-2, G-4). 5. Fermentation period of Geep-Jang may reduce by addition of cellulolytic enzymes.
즙장(汁醬)을 곡류(穀類) 이외(以外)에 가지, 오이, 고추와 같은 야채류(野菜類)를 원료(原料)로 하여 고온(高溫)$(55{\sim}60^{\circ}C)$)과 실온(室溫)에서 약(約) 일주일내(一週日內) 발효숙성(醱酵熟成) 시키면서 숙성중(熟成中) 일반성분(一般成分)의 변화(變化)를 측정(測定)하였고 섬유소류(纖維素類) 분해효소(分解酵素)의 첨가(添加)에 의(依)한 원료분해(原料分解) 촉진관계(促進關係)를 실험(實驗)한 결과(結果)는 다음과 같다. 1) 당분(糖分)은 각(各) 구(區)가 담금 후 $20{\sim}40$시간(時間) 후(後)에 급격(急激)히 증가(增加)하였다. 2) G-5에서 당분(糖分)이 제일 많았던 것은 탄수화물원(炭水化物源)이 많았고 섬유소류(纖維素類) 분해효소(分解酵素)에 의(依)한 당분생성(糖分生成)이 촉진(促進)된 것이라고 볼 수 있다. 3) G-1과 G-3의 당분생성률(糖分生成量)의 차이(差異)는 효소액(酵素液) 첨가(添加)의 유무(有無)에서 온 것이라고 볼 수 있으며 재래식(在來式) 메주가루를 사용(使用)하였을 때는 이 차이(差異)가 더욱 현저(顯著)하였다. 4) Amno-Nitrogen는 효소액(酵素液)을 첨가(添加)한 구(區)가 대조구(對照區)보다 대체적(大體的)으로 많았다. 5) 섬유소류분해효소(纖維素類分解酵素)를 첨가(添加)하면 장류(醬類) 숙성기간(熟成期間)을 단축(短縮)시킬 수 있다.
