Strawberry and cucumber were dipped with Korean medical herb extracts such as Rheum palmatum L. and Coptis chinensis Franch. to maintain the keeping quality during storage at 5C and 10C, respectively. Treatment with 500 ppm solutions gor strawberry retarded weight loss, microbial load increase, and decay during storage. Decay ratio was shown 68.8% for control, 45.0% for Rheum palmatum L. and 42.5% for Coptis chinensis Franch. at 10 days. Strawberry treated with Coptis chinensis Franch. showed a higher hardness and soluble solid content than others. Cucumber treated with 1,000 ppm solutions revealed a different O and CO concentrations after 16 days. Korean medical herb extracts showed an antimicrobial activity for the quality retention of cucumber during storage. Ascorbic acid content was generally increased till 8 days, but decreased thereafter.

항균력이 있는 것으로 확인된 대황 및 황련추출물을 오이, 호박, 상치 및 고추에 처리하였을 때 총균수가 감소하였다. 채소의 종류에 따라서 적절한 처리농도는 달랐는 데, 호박, 상치 및 고추는 100 ppm, 오이는 500 ppm 처리가 적절한 것으로 나타났다. 채소를 침지할 때의 시간은 10분 정도가 적절한 것으로 나타났으며, 세척수의 온도를 4로 높일 경우에도 채소류 표면의 총균수 감소 효과는 실온의 세척수와 비슷하였다. 또한 오이와 호박을 대
