즙장은 중국의 조리서에 수록되지 않은 순수 우리나라 속 성장으로 많은 종류가 있었으나, 보존성 문제로 대부분 맥이 끊겨서 전해지지 않기 때문에 조선시대 및 1950년 이전 조리 서의 즙장을 조사하여 밝혔다. 그 중 가지와 오이 등의 채소를 넣는 즙장은 34 가지, 넣지 않는 즙장은 9가지였다. 즙장의 주 재료는 콩과 밀기울이며, 보리, 메밀도 쓰였다. 즙장메주는 빨 리 뜨게 하기 위하여 일반메주보다 작게 만들었는데, 작은 알 형태가 가장 많고, 납작하거나 둥근 칼자루 형태도 있다. 즙장 은 메주가루를 소금과 물로 이겨서 담그는 것이 가장 많다. 함께 쓰는 것으로는 누룩가루, 밀기울, 밀가루, 술, 말장, 간장, 엿기름, 탁주 등이 있다. 즙장메주는 용기에 넣어서 띄우는 것 도 있고, 넣지 않고 띄우는 것도 있는데, 용기는 섬과 둥구미 가 가장 많고, 버드나무그릇, 치룽, 독도 사용하며, 즙장메주 의 깔개 및 덮개는 닥나무 잎을 가장 많이 사용하고, 그 외에 짚, 북나무잎, 뽕잎, 가랑잎, 솔잎, 콩잎도 사용한다. 즙장은 다 른 장과 달리 말똥, 두엄, 풀더미에 묻혀서 이들이 썩으면서 내는 60~65℃의 열로 가열하여 숙성시킨다. 즙장은 맥이 끊기 거나 쩜장, 지례장, 무장, 빠금장, 막장, 집장, 토장 등의 형태 로도 변하였다. 이들 장은 즙장에서 사용하지 않는 쌀, 엿기 름, 고춧가루 등을 사용하고 있는 점에서 다르다.

This paper investigated the system that is relevant to Jang(fermented soybean paste or solution), the relief of hunger- stricken people by Jang, 33 kinds of Jang, and its consumption in the documents, such as the annals of the Chosun Dynasty, Ihlseong-document, Seungjeongwon daily, Uigwe(record of national ceremony), official documents on the basis of Kyujanggak institute for the Korean studies and data base of Korean classics. There are lots of Jang named after the place of particular soybean's production from the ancient times. Jang, soybean, salt and Meju(source of Jang), during the Dynasty, were collected as taxation or tribute. In the 5th year of Hyeonjong(1664), the storage amount of soybean in Hojo(ministry of finance) was 16, 200 ㎘, and its consumption was 7, 694 ㎘ a year. In the 32nd year of Yongjo(1756), the 1, 800 ㎘ of soybean was distributed to the people at the time of disaster, and in his 36th year(1756), the 15, 426 ㎘ of soybean was reduced from the soybean taxation nationwide. The offices managing Jang are Naejashi, Saseonseo, Sadoshi, Yebinshi and Bongsangshi. Chongyoongcheong(Gyeonggi military headquarters) stored the 175.14 ㎘ of Jang, and the 198 ㎘ of Jang in Yebinshi. There are such posts managing Jang as Jangsaek, Jangdoo, and Saseonsikjang. In the year of Jeongjong(1777～1800), the royal family distributed the 3.6 ㎘ of Meju to Gasoon-court, Hygyeong-court, queen's mother-court, queen's court, royal palace. The 13.41 ㎘ of Gamjang(fermented soybean solution) was distributed to the Gasoon-court, 17.23 ㎘ to Hegyeong-court, 17.09 ㎘ to the queen's mother-court, and the 17.17 ㎘ to the queen's court each. There are 112 Jang-storing pots in the royal storages, and the 690 are in Namhan-hill, where the 2.7 ㎘ of fermented Jang was made and brought back by them each year. At the time of starvation, Jang relieved the starving people. There are 20 occasions of big reliefs, according to the annals of the Chosun Dynasty. In the 5th year of Sejong(1423), the 360 ㎘ of Jang was given to the hunger-stricken people. In his 6th year(1424), the 8, 512.92 ㎘ of rice, bean, and Jang was provided and in the 28th year(1446), the 8, 322.68 ㎘ of Jang was also provided to them. In the Dynasty, Jang was given as a salary. In case that when they were bereaved, they didn't eat Jang patiently for its preservation. They were awarded for their filial piety. In the annals of the Chosun Dynasty, there are 19 kinds of Jang. They are listed in the order of Jang(108), Yeomjang(90), Maljang(11), Yookjang(5), Gamjang(4), and etc., . In Seungjeongwon daily, there are 11 kinds of Jang. Jang(6), Cheongjang (5), Maljang(5), and Tojang(3) are listed in order. In the Ihlseong-document, there are 5 kinds of Jang. They are listed in Jang(15), Maljang(2), Gamjang(2), and etc., . There are 13 kinds of Jang in Uigwe, and the official documents, in the order of Gamjang(59), Ganjang(37), Jang(28), Yeomjang(7), Maljang(6), and Cheongjang(5). In addition, shi are Jeonshi(7), and Dooshi(4). All these are made of only soybean except, for Yookjang. The most-frequently recorded Jang among anthology, cookbook, the annals of the Chosun Dynasty, Ihlseong-document, Seoungjeongwon daily, Uigwe, or officialdocument is Jang(372), and then Yeomjang(194), Gamjang(73), Cheongjang(46), Ganjang(46), Soojang(33), and Maljang(26), which were made of soybean. Jang from China in cookbook is not in anthology and royal palace documents. Thus, traditional Jang made of soybean was used in the daily food life in the royal court, and in the public during the Chosun period.

경상도지방의 전통적인 등겨장제법을 조사하고 10종의 시료를 채취하여 성분분석 및 관능시험으로 품질을 평가하였다. 등겨장의 맛을 좋게 하기 위하여 부원료는 적당량의 콩 등을 첨가하여 주로 자연 숙성방법으로 등겨장을 제조하고 있다. 전통 등겨장의 성분 중 아미노태질소 함량은 낮았으며 수용성 및 염용해성 단백질의 아미노산 조성은 다같이 glutamic acid, aspartic acid 및 proline의 함량이 많았다. 등겨장의 당의 함량은 대체로 높았으며 유리당 중 glucose의 함량이 2.16~4.02 mg/ml로써 가창 많았고 maltose, matotriose 순이었다. 산성 protease의 활성은 0.13~1.36 unit/ml였으며 전분액화력은 10.18~15.19 D40o30으로서 등겨장의 감미를 크게 증가시켰다. 관능시험의 결과 선정된 3종류의 우량 등겨장은 매운맛과 단맛, 산미가 잘 조화된 전통식품으로 향기는 약간의 메주향에다 매운맛이 잘 조화된 향취를 나타내었다.
