Abstract
Description
본 발명은 메주의 제조 방법에 관한 것으로서, 특히 고초균을 이용하여 전통적인 맛을 가지는 메주를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing meju, and more particularly, to a method for producing meju having a traditional taste using Bacillus subtilis.
전통적인 방법에 의한 메주의 제조 방법은, 늦은 가을에서 겨울 사이에 대두를 삶은 다음 절구로 찧고, 메주 덩어리를 만들어서 메주 덩어리를 볏짚으로 묶은 후 겨우내 벽에 매달아 말리는 방법이다. 이 과정에서 볏짚의 고초균과 공기 중의 곰팡이들이 자연적으로 접종된다. 숙성이 완료되면 표면의 곰팡이를 물로 씻은 후 말려서 장을 담그는데 사용한다.The traditional method of making meju is a method of boiling soybeans from late autumn to winter, then steaming them with mortar, making meju chunks, tying them together with straw, and hanging them on the wall in winter. This process inoculates rice straw subtilis and fungi in the air naturally. When the maturation is complete, the surface of the fungus is washed with water, dried and used to soak the intestines.
최근에 공장에서 대량으로 메주를 제조하기 위하여 순수한 단일균으로서 곰팡이의 일종인 황곡균(Aspergillus oryzae)을 사용하는 개량식 메주 제조 방법이 소개되었다. 이 방식은 일본의 국제법(麴製法)을 도입한 것으로서, 대두를 삶은 후 황곡균을 인위적으로 접종하여 30℃ 정도의 온도에서 3일간 배양하는 것이다.Recently, in order to manufacture meju in large quantities in a factory, an improved method of producing meju using a fungus of Aspergillus oryzae as a pure single bacterium was introduced. This method introduces Japanese international law. After soybeans are boiled, artificially inoculated with H. bark and incubated at 30 ° C for 3 days.
상기한 바와 같은 전통적인 방법과 개량 방법은 각각 다음과 같은 문제점이 있다.The traditional method and the improvement method as described above have the following problems, respectively.
전통적인 방법에서는 우량한 균주의 선택이 없이 자연 접종에 의한 숙성이므로 강력한 단백질 분해력이 없이 메주의 수율이 떨어지며, 유해한 잡균의 오염이 빈번하여 메주의 풍미가 균일하지 않은 단점이 있다.In the traditional method, since the ripening by natural inoculation without selection of a superior strain, the yield of meju is reduced without strong protein degrading power, and there is a disadvantage that the flavor of meju is not uniform due to frequent contamination of harmful bacteria.
한편, 개량식 방법에서는 곰팡이의 일종인 황곡균만을 사용하므로 단백질 분해력은 우수하나, 전통적인 방법에서 사용된 볏짚의 고초균이 들어가지 않아서 재래식 메주의 고유한 풍미를 느낄 수 없는 단점이 있다.On the other hand, in the improved method, because only the fungus, a type of fungus, which has a high protein degradation ability, but the traditional rice paddy used to eliminate the subtle bacteria of the traditional rice wine has a disadvantage that can not feel the unique flavor.
본 발명은 목적은 상기한 바와 같은 전통적인 방법과 개량식 방법의 단점을 해결하기 위한 것으로서, 재래식 메주의 풍미를 생성하는 균주인 고초균을 인위적으로 접종하여 숙성시켜서 얻어진 고초균을 이용한 메주 제조 방법을 제공하는 것이다.An object of the present invention is to solve the shortcomings of the conventional method and the improved method as described above, and to provide a method for preparing meju using Bacillus subtilis obtained by artificially inoculating and ripening Bacillus subtilis, a strain that produces a flavor of conventional meju. .
