Impact of Lauric Arginate Application Form on its Antimicrobial Activity in Meat Emulsions

Control of listeria in meat emulsions by combinations of antimicrobials of different solubilities

“…One should take the high extension time at 40 x 10 3 µg/g with some caution since at this concentration, sodium lactate noticeably affects the sensory qualities of the product. Calculation of the growth retardation obtained by modeling the CFU vs time relationship by a shifted logistic function yielded similar results for individually applied antimicrobials and their binary solutions (Dai et al, 2010;Terjung et al, 2013). We therefore chose not to show those results.…”

“…In consequence, higher concentrations of antimicrobials are needed to achieve control of microorganisms. Recent research has shown that this is because antimicrobials may interact with proteins rendering them less available for interaction with microorganisms (Terjung et al, 2013). To date, it is not yet fully understood which molecular properties truly govern these interactions that then render antimicrobials less effective.…”

“…Solutions were prepared by dilution of 50% sodium lactate solution in double-distilled water to the concentrations desired. LAE was applied as solid lipid particles (SLP) that had previously been shown to be the most effective LAE application system for meat-based systems (Terjung et al, 2013). There, a coarse pre-emulsion was prepared by homogenizing 10 wt% melted for 12 h at room temperature prior to use.…”

“… First, the chosen antimicrobials in their application form (lactate as an aqueous solution, methylparaben as a powder and lauric arginate as solid lipid particles (Terjung et al, 2013)) can be incorporated in an emulsion type sausage matrix without causing structural alterations such as emulsion breakage or disruption of protein network formation.…”

Antimicrobial Edible Films and Coatings for Meat and Meat Products Preservation

“…It is obtained through the reaction of L-arginine, hydrochloric acid, ethanol, thionyl chloride, sodium hydroxide, lauryl chloride, and deionized water [80]. LAE affects cells viability by disturbing membrane potential and causing structural changes, although no disruption of cells is detected.…”
