Abstract

To make kochuzang, mixtures of rice and sake cake were used as a source of starch and a small part of sodium chloride needed was replaced by mixtures of ethanol and garlic. Amylase activity during aging of kochuzang was increased in proportion to the ratio of sake cake to rice. Protease activity reached a maximum in the sample replaced 25% of rice with sake cake. The counts of aerobic bacteria and molds were decreased according to the increased ratio of sake. Total acidity and the content of alcohol and amino nitrogen were increased during aging of kochuzang, but the change of pH and the content of reducing sugar were small. After 70 days of aging, the taste and flavor of kochuzang was showed to be excellent in the sample replaced 25% of rice by sake cake. Therefore, it may be possible to replace 25% of rice by sake cake.

전분질원의 일부로 청주박을 이용하고 식염의 일부를 알코올과 마늘로 대체한 저식염 고추장을 제조하였다. 숙성 중의 amylase 활성도는 청주박의 배합비가 증가할 수록 대체로 증가하였으나 protease의 경우는 25% 배합구에서 높았다. 청주박의 배합비가 증가할수록 고추장 숙성 중의 호기성 세균과 곰팡이수는 감소하였다. 또 숙성 중의 pH 변화와 환원당량의 증가는 적었으나 적정산도와 알코올 및 아미노태 질소량은 증가하였다. 70일 숙성시킨 고추장의 맛과 향기는 쌀 대신 청주박을 25% 배합한 구에서 우수하여 저식염 고추장 양조시청주박을 일부 배합함으로써 품질의 향상을 기대할 수 있었다.
