천연보존제인 참나무 목초액을 항균제 및 주방기구 세척시 소독제로 활용하기 위하여 식품부패균 및 식중독균에 대한 항균효과를 조사하였다. Paper disc법에 의한 시험결과 모든 시험균주에 대하여 20 첨가시 항균효과를 나타내었으며, 미생물이 첨가된 배지에 참나무 목초액을 70 첨가한 후 에서 3일간의 배양동안 모든 시험균주의 성장이 완전히 억제되었다. 증류수로 희석한 목초액 50에 대수증기까지 배양하여 멸균수로 희석한 대장균을 미량 첨가하여 에서

Antimicrobial activities of oak smoke flavoring against saprogenous and food poisoning microbes were studied. When tested on a paper disc, antimicrobial activities were observed in all microbial species at a dose of as low as 20 , and microbial growth was completely suppressed with 70 during 3 days of incubation at with 8 times diluted oak smoke flavoring. When 50 of distilled water and distilled water containing 500 of oak smoke flavoring, which were added with small amount of dilute E. coli, were incubated for 10 days at , CFU/ of E. coli and CFU/ of total bacteria was counted in distilled water containing oak smoke flavoring.
