Patent

CA 2399801

A concentrated quaternary ammonium compound (QAC) solution comprising a QAC with a concentration from greater than about 10% by weight and at least one solubility enhancing agent, such as an alcohol, is disclosed. A diluted QAC solution is used to contact food products to prevent microbial growth on the food products from a broad spectrum of foodborne microbial contamination. A method of contacting the food products with the dilute QAC for an application time of at least 0.1 second is disclosed. The foods that can be treated by this method are meat and meat products, seafood, vegetables, fruit, dairy products, pet foods and snacks, and any otherfood that can be 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.

L'invention concerne une solution concentrée de composés d'ammonium quaternaire renfermant un composé d'ammonium quaternaire à une concentration supérieure à 10 % en poids environ et au moins un agent solubilisant, notamment un alcool. On utilise cette solution de composés d'ammonium quaternaire diluée sur les produits alimentaires pour empêcher la croissance microbienne sur lesdits produits alimentaires d'un large spectre de contaminations microbiennes d'origine alimentaire. L'invention concerne également un procédé de mise en contact desdits produits alimentaires avec le composé d'ammonium quaternaire dilué, pendant un temps d'application d'au moins 0,1 seconde. Les aliments qui peuvent être traités par ce procédé sont la viande et les produits carnés, les fruits de mer, les légumes, les produits laitiers, les aliments pour animaux de compagnie et les en-cas, ainsi que tout autre type d'aliments qui, même traités, conservent leur aspect et leur texture. L'un de ces procédés de traitement consiste à pulvériser en brouillard lesdites solutions de composés d'ammonium quaternaire sur les produits alimentaires pendant un temps d'application d'au moins 0,1 seconde, de manière à éviter un large spectre de contaminations microbiennes d'origine alimentaire.
