Lauric Arginate

Apples are naturally coated with a water-repelling hydrophobic wax layer, which may limit the antimicrobial efficacies of surface sanitizer solutions. Lauric arginate (LAE) is a cationic surfactant with antimicrobial efficacy against Listeria monocytogenes. In this study, we investigated the antimicrobial and the wettability effects of LAE in enhancing anti-L. monocytogenes efficacy of peracetic acid (PAA) and further verified the optimized treatment combinations in a pilot spray-bar brush bed system. Apples after 48 h of inoculation were treated with PAA surface sanitation in combination with different concentrations of LAE at 22 or 46°C. The effectiveness of PAA with LAE solutions in decontaminating L. monocytogenes significantly increased with the increased concentration of PAA (60–80 ppm) or LAE (0.01–0.05%) or the treatment temperature (from 22 to 46°C). A 30–120-sec wash by 80 ppm PAA with 0.01 and 0.05% LAE at 22°C reduced L. monocytogenes on apples by 2.10–2.25 and 2.48–2.58 log10 CFU/apple, respectively. Including LAE in the PAA solution decreased contact angles on apple surfaces. However, the increased wettability of the sanitizer solution may not be the main contributor to the enhanced antimicrobial efficacy of the PAA solution, given that the addition of Tween 80 or Tween 85 only slightly boosted the anti-L. monocytogenes efficacy of PAA solutions though both increased the wettability of the PAA solutions. The synergistic effects of PAA and LAE were further validated in a pilot spray-bar brush bed packing system, where a 30-sec spray wash with 80 ppm PAA and 0.05% LAE at 22 and 46°C caused 1.68 and 2.08 log reduction of Listeria on fresh apples, respectively. This study provides an improved PAA process/preventive strategy for ensuring microbial food safety of fresh apples that is applicable to commercial apple packing lines.

Приведены данные двухлетнего исследования по поиску эффективных препаратов для обеззараживания семян капусты от сосудистого бактериоза. Наилучший результат был получен при предпосевной обработке 0,15%-ной надуксусной кислотой. При этом биологическая эффективность составляла 94,1–97,6%, что значительно превышало соответствующий показатель в эталонном варианте – Фитолавин, ВРК, 0,2% (69,0–72,0%). Показано, что заблаговременная обработка семян НУК (за 550 суток до посева) не оказывала достоверного влияния на их лабораторную всхожесть.Presented data are the result of a two-year study aimed at identifying effective preparations for the disinfection of cabbage seeds from black rot. The best result was obtained by presowing treatment with 0.15% peracetic acid. In this case, the biological efficiency was 94.1–97.6%, which significantly exceeded the corresponding indicator in the reference variant – Phytolavin, VRK, 0.2% (69.0–72.0%). The study has not revealed any significant effect of advance treatment of seeds with peracetic acid (550 days before sowing) on their laboratory germination.
