Impact of lauric arginate application form on its antimicrobial activity on the surface of a model meat product.

Unlabelled: This study evaluated the antimicrobial effect of N(α)-Lauroyl-L-arginine ethyl estermonohydrochloride (lauric arginate), sodium lactate, and sodium diacetate at various concentrations against Listeria innocua, Escherichia coli C600, and Lactobacillus curvatus (10(2) CFU/g) on "Lyoner style" sausage slices as a function of application form. We want to investigate if the results of a surface application of lauric arginate in various applications forms may differ from that of an in-matrix application since different physicochemical processes occur at surfaces than in matrices. Lauric arginate was applied on the surface of meat emulsions as aqueous solution, as oil-in-water emulsion, and as solid lipid particles.
