CA 2711453

Antimicrobial compositions are provided comprising a pharmaceutically acceptable organic acid and a pharmaceutically acceptable surfactant. This synergistic combination allows compositions to be formulated at low concentrations that have efficacy in reducing bacterial counts by greater than 3 log within 5 minutes of contact while preserving the organoleptic properties of treated foods, including fresh produce. As shown in Fig. 1C the efficacy of six different compositions (A. 3% levulinic acid plus 2% SDS; B. 2% levulinic acid plus 1% SDS; C. 0.5% levulinic acid plus 0.05% SDS; D. 3% levulinic acid; E. 2% SDS and F. water) were tested for their ability to kill spores of Bacillus anthracis Sterne after 45 minutes of contact.

L'invention porte sur des compositions antimicrobiennes comportant un acide organique de qualité pharmaceutique et un agent tensioactif de qualité pharmaceutique. Cette combinaison synergique permet à des compositions d'être formulées à de faibles concentrations qui ont une efficacité dans la réduction de comptages bactériens de plus de 3 log dans les 5 minutes suivant la mise en contact tout en conservant les propriétés organoleptiques d'aliments traités, y compris des légumes et fruits frais. Comme représenté sur la Figure 1C, l'efficacité de six compositions différentes (A. 3 % d'acide lévulinique plus 2 % de SDS; B. 2 % d'acide lévulinique plus 1 % de SDS; C. 0,5 % d'acide lévulinique plus 0,05 % de SDS; D. 3 % d'acide lévulinique; E. 2 % de SDS et F. eau) a été analysée pour déterminer laptitude des compositions à tuer les spores de Bacillus anthracis Sterne après 45 minutes de contact.
