Abstract

The use of synthetic additives for preservation and enhancement of the market quality of food products has been emerging as a societal issue in terms of safety as well as changes in consumption patterns. Various research related to natural additives is being conducted to address these issues. This study examined the antibacterial effects of 79 types of medicinal herbs used as oriental remedies on bacteria isolated from beverages of damaged marketable quality. The antibacterial effects of methanol extracts on 13 Bacillus sp. and three Paenibacillus sp. were evaluated. We found that 43 of the herbal medicines analyzed had antibacterial effects on the isolated bacteria. Of those, eight were selected, and their antibacterial effects were further examined using water, ethanol, methanol, and ethyl acetate as solvents. The results revealed that Prunus mume, Rhus javanica, and Coptis japonica had excellent antibacterial effects against the isolated bacteria. In particular, they exerted greater antibacterial effects when water and ethanol were used as solvents. This result indicates the possibility of developing natural additives using these substances. Since P. mume in particular, has not been sufficiently studied compared to other herbal medicines, it presents an opportunity for additional investigation and the possibility for development as a new product in the future.
