  • Publication number: 20220079158
    Abstract: Compositions and methods that utilize a combination of essential oils or other plant-derived extracts or compounds and an emulsifier as an antimicrobial are provided. In some embodiments the compositions further include ozone. In some embodiments, the composition includes one or more plant essential oils, plant extracts, or plant-derived compounds, or combinations thereof, and an emulsifier (such as a saponin). The antimicrobial composition may also include water, peracetic acid, acetic acid, lactic acid, citric acid, and/or hydrogen peroxide. Methods of killing a microorganism, including contacting the microorganism with the disclosed antimicrobial compositions are also provided. The microorganism may be present on a food item or a food contact of non-food contact surface and may be in the form of a biofilm. In some examples, the antimicrobial composition is used one or more times (such as 1 to 5 times).

  • Publication number: 20220039411
    Abstract: Antimicrobial compositions derived from edible plant sources such as essential oils, their active components, spices and plant extracts have shown antimicrobial effects against a number of foodborne pathogens. The foodborne pathogens of concern in meat and poultry products include Salmonella enterica, Escherichia coli O157:H7 and Listeria monocytogenes. The antimicrobial compositions were applied to a meat surface using liquid or powder electrostatic spray systems to effectively reduce the amount of pathogens on various meat and poultry products.

  • Patent number: 9661856
    Abstract: Citral, cinnamaldehyde, carvacrol, and allspice oil were found to be highly effective antimicrobials, producing statistically significant reductions in Escherichia coli populations within minutes. In addition, synergy was observed between silver ions and these essential oils, thereby lessening the amount of the plant antimicrobial required to produce the same effect. Based on these observations, compositions including these agents and there use as an antimicrobial treatment that is safe for human consumption, are active in the presence of organic matter, are provided.
