摘要: UNLABELLED This study aimed at using essential oil (EO) alone or combined EO with nisin and γ-irradiation to control Salmonella Typhimurium during the refrigerated storage of mini-carrots. Peeled mini-carrots were inoculated S. a final concentration approximately 7 log CFU/g. Inoculated samples coated by 5 different coating solutions: (i) solution 10(3) IU/mL; (ii) mountain savory 0.35%; (iii) carvacrol (iv) 0.35% plus (v) IU/mL. Coated then irradiated 0.5 1.0 kGy compared an unirradiated sample. Samples kept 4 °C microbial analyses conducted days 1, 3, 6, 9. The results showed that in combination irradiation completely eliminated under detection limit storage. Thus, treatments could be used as effective method for controlling PRACTICAL APPLICATION shows effect γ low dose (1 kGy) reduce significantly growth typhimurium It also nisin, oils have best antibacterial effects against can practical application food industry terms safety.
