摘要

获得不含化学或合成添加剂的健康食品是一项重大挑战。在本研究中，我们开发了一种使用精油的保存方法，并评估了它们对多药耐药致病性革兰氏阴性菌的影响。采用不同浓度（1%、0.1%、0.17%和0.35%）的百里香油和黑籽油对软干酪中的致病性大肠杆菌和嗜水气单胞菌进行了研究。用过的油在0.1%的浓度下通过浸渍法产生可接受的颜色和气味，对风味和正常质地和外观的影响很小，而在接种过程中0.1%的油除了中等气味外与浸渍法具有相同的效果。百里香油对嗜水气单胞菌的还原率在1%浸渍和0.17%接种时最高，而对大肠杆菌的还原率则在0.17%接种和0.35%浸渍时最高。百里香精油似乎是一种合适的天然食品防腐剂替代品。

EFFECT OF ESSENTIAL OILS ON MULTIDRUG RESISTANT GRAM-NEGATIVE BACTERIA

Obtaining healthy food, free from chemical or synthetic additives, is a major challenge. In this study, we developed a preservation method using essential oils and evaluated their effect on multidrug resistant pathogenic Gram-negative bacteria. Different concentrations (1%,0.1%,0.17% and 0.35%) of Thyme oil and black seed oil were employed in this study against pathogenic E. coli and A. hydrophila in soft cheese. The used oils at a concentration of 0.1% through dipping method resulted in accepted color and odor, little effect on flavor and normal texture and appearance, while 0.1% during inoculation had the same effect as in dipping method except moderate odor. Thyme oil had the highest reduction rate in case of 1% dipping and 0.17% inoculation on A. hydrophila, while against E. coli it was found that 0.17% inoculation and 0.35% of the dipping method had the highest reduction effect. Thyme essential oil seems to be a suitable natural food preservative alternative.
