Patent number: 8323673Abstract: 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.Type: GrantFiled: November 4, 2011Date of Patent: December 4, 2012Assignee: University of ArkansasInventors: Cesar Compadre, Philip Breen, Hamid Salari, E.
