中文摘要 | 本研究主要探討刀╱砧除菌烘乾機對五種食品病原菌之殺菌條件。每一菌株以 10 �揭� 10 �� CFU/cm �斯}釋度分別塗抹於刀與砧板表面上,在所使用菌株中, 我們發現 腸炎弧菌不管以 UV 燈單獨照射或加熱處理皆為最敏感菌株。為達 99 %之殺菌效率,金黃 色葡萄球菌需經加熱處理 180 分鐘。 就仙人掌桿菌而言,以 UV 照射 20 分鐘或加熱處理 25 分鐘都可獲得不錯之殺菌效果。相較之下,UV 照射對刀與砧板之殺菌效果都比加熱處理 來得好。這些結果顯示刀╱砧除菌烘乾機對存在刀或砧板上之食品病原菌之殺菌非常有用。 |
英文摘要 | The disinfection conditions for five food-borne pathogens were investigated using a knife/chopping block dish dryer. Each of the strains was inoculated separately at the dilution levels of 10 �� to 10 �� CFU/cm �� onto the surfaces of knife and chopping block. Among the pathogens tested, we found that Vibrio parahaemolyticus was the most sensitive strain to either ultraviolet (UV) irradiation alone or in combination with heating. In order to obtain a disinfection efficiency of 99%, a 180-min heating process for Staphylococcus aureus was required. An efficient disinfection for Bacillus cereus was observed under a 20-min UV irradiation or a 25-min heating process. By comparison, UV irradiation had a better effect than heating process on both knife and chopping block. These results suggested that the knife/chopping block dish dryer is useful for sterilization of food-borne pathogens colonized on knife or chopping block. |
