PROBLEM TO BE SOLVED: To obtain the subject antibacterial agent effective, in particular, against food positioning bacteria such as pathogenic Escherichia coil O-157 and Legionella bacterial, by including phytonicide and organic matter bearing tropolone skeleton. SOLUTION: This antibacterial agent contains, as active ingredients, (A) pref. 0.3-30 wt.% of phytoncide (e.g. an extract prepared by extracting about 180 kinds of organic compounds using each unique squeezing equipment and vacuum dry distillation column from 35 kinds of plants with the main stocks including Cryptomeria japonica, white cedar (Hinoki), Abies firma, Urtica thumbergia, Cinnamomum camphora, Pins Thunbergii, Pinus densiflora, Picea jezoensis, persimmon, Sasa albo-marginata, Artemisia princeps, tea, Betula tauschii, perilla frutescens crispa, aloe, Zanthoxylum piperitum and Gynostemma pentaphyllum, followed by blending the resultant respective extracts), and (B pref. 0.1-2 wt.% of organic substance(s) bearing tropolone skeleton (e.g. hinokitiol, β-dolabrin), and pref. further, (C) 0.5-10 wt.% of an emulsifier and (D 0.5-5 wt.% of organic acid(s). It is preferable that this antibacterial agent is made to a gel-like material by the further addition of a gelatinizer. |
