화분의 발아조건에 따른 식품유해균에 대한 항균성을 비교 조사하였다. 그 결과 10%(w/v)설탕용액에 화분 8%(w/v)를 첨가하여 에서 4일간 발아시켰을 때 식품유해균에 대한 항균활성이 가장 높게 나타났다. 화분발아액의 최소저해농도를 그람양성세균은 , 그람음성세균은 에서 균생육이 억제되는 것으로 나타났다. 화분발아액의 유기산을 조사한 결과 acetic acid와 lactic acid의 함량이 높은 것으로 나타났다. 화분발아액의 열과 pH 안정성
This study investigated the antimicrobial effect of germinated acorn pollen solution on harmful food-borne microorganisms. The antimicrobial activity when 8% (w/v) acorn pollen in 10% (w/v) sugar solution was extracted at for 4 days. The minimal inhibitory concentration of this germinated acorn pollen solution was for Gram-positive bacteria and for Gram-negative bacteria. Acetic and lactic acids were present at high levels in germinated acom pollen solution. As pollen germination releases heat, the antimicrobial activities are heat-stable. The activities are tolerant of low pH. In summary, acorn pollen germination solution showed active antibiosis and should be developed as a natural preservative material.
