  • We added Nuruk at various proportions to brown rice Takju, and investigated the quality characteristics of vinegar produced in agitated culture and static culture. The more Nuruk was added, the higher the alcohol concentration. However, when over 30% (w/w) Nuruk was present, the increment in alcohol content was low (maximum 13.5%, v/v). A comparison of the quality of brown rice vinegar produced in agitated culture with that of vinegar produced in static culture showed that titratable acidity in agitated culture vinegar was highest after fermentation with 30% (w/v) Nuruk, at 5.97%. In static culture, the greater the amount of Nuruk added after 16 days of fermentation, the higher the titratable acidity of vinegar produced; this was true upon addition of either 30% (w/v) or 40% (w/v) Nuruk. Free amino acid levels increased in both agitated and static cultures as the level of added Nuruk rose. Moreover, brown rice vinegar produced in static culture had a higher level (7-30%) of total free amino acids than did vinegar produced in agitated culture. In particular, the level of gamma-amino butyric acid, a functional fortifier, was 3-5-fold higher in vinegar produced in agitated culture. The results thus indicate that both the amount of added Nuruk and the type of fermentation affected the level of free amino acid production. A static culture is expected to undergo changes in aroma and sensory characteristics during fermentation, indicating that further research on vinegars is required.

  • 우리나라의 전분원료는 74년 이후 옥수수를 주로 사용함에 따라 부산물로써 폐기되는 전분박은 전국적으로 약 2,000M/T으로 추산된다. 이 전분박을 산당화처리하여 식전 및 가축, 양어사료제조를 목적으로 효모를 배양하는 실험을 하였다.(중략)
