perfringens, Bacillus subtilis, and Alicyclobacillus acidocaldarius). Avosafe® (15 µg disc −1) inhibited Gram-positive bacteria, with higher efficacy towards spore-formers ( Clostridium sporogenes, C. Avocado seed extract (Avosafe®) contained 71.3% w/w total acetogenins, its main components were AcO-avocadene and persenone A (22.05 ± 1.84 and 20.14 ± 1.40% w/w, respectively). Acetogenins were also added to a food system containing meat, inoculated with Listeria monocytogenes and stored at 20☌ and 4☌. Additionally, eight Gram-positive bacteria were exposed to commercial food preservatives (Nisaplin® and Mirenat®) for comparison. In this study, antimicrobial spectrum of purified acetogenins was characterized. Avocado fruit contains lipid derivatives with antimicrobial properties called acetogenins.
