Patent

CA 2240930

Methods for the reduction of levels of gram negative and gram positive bacteria are disclosed which involve treatment with a solution of low concentration alkali metal orthophosphate combined with either osmotic shock and/or subsequently a lysozyme in solution and/or nisin in solution. The combination process is synergistic in extending the range of effective killing of bacteria and enables the use of more desirable processing parameters than the previous techniques and is particularly suitable for food processing.

L'invention concerne des procédés permettant de diminuer le taux de bactéries Gram négatives et Gram positives, et qui comportent le traitement par une solution faiblement concentrée d'un orthophosphate de métal alcalin combiné à un choc osmotique et/ou à un lysozyme en solution et/ou à de la nisine en solution. Le procédé de combinaison est synergique en ce qu'il élargit la plage de destruction effective des bactéries, il permet d'utiliser des paramètres de traitement plus adaptés que les techniques antérieures et il convient particulièrement bien pour le traitement des produits alimentaires.
