  • Publication number: 20220332692
    Abstract: Tocol derivative compounds, compositions comprising these tocol derivatives and methods of using the tocol derivatives are provided herein. Specifically the tocol derivatives have a partially unsaturated hydrocarbon tail and are thus distinct from the tocopherols. The hydrocarbon tails do not have a trans carbon-carbon double bond in the second isoprene unit of the hydrocarbon tail and are distinct from the tocotrienols. The compounds are expected to allow improved interaction with the a-tocopherol transfer protein receptor than the tocotrienols and better bioactivity than the tocopherols.

  • Patent number: 8323673
    Abstract: A concentrated quaternary ammonium compound (QAC) solution comprising a QAC with a concentration greater than about 10% by weight and at least one solubility enhancing agent, such as an alcohol, is disclosed. A diluted QAC solution is useful on food products to prevent microbial growth on the food from a broad spectrum of foodborne microbial contamination. Also disclosed is a method of contacting food products with the dilute QAC for an application time of at least 0.1 second. Foods that can be treated by this method are meat and meat products, seafood, vegetables, fruit, dairy products, pet foods and snacks, and any other food that can be 10 treated and still retain its appearance and texture. One of the treatment methods is spraying and misting the QAC solutions on the food products for an application time of at least 0.1 second to prevent broad spectrum foodborne microbial contamination.

  • Publication number: 20050239850
    Abstract: A method of using quaternary ammonium compounds for inhibiting attachment of and removing a broad spectrum of foodborne microbial contamination from food products. The method uses quaternary ammonium compounds for inhibiting attachment of and removing microorganisms such as, Staphylococcus, Campylobacter, Arcobacter, Listeria, Aeromonas, Bacillus, Salmonella, non-toxin-producing Escherichia, and pathogenic toxin-producing Escherichia, such as 0157:H7; fungi, such as Aspergillus flavus and Penicillium chrysogenum; and parasites, such as Entameba histolytica from a broad range of food.
