La concentración de acetogeninas totales en el extracto de semilla de aguacate (Avosafe®) fue de 71.3 % p/p, de las cuales AcO-avocadeno y persenona A (22.05 ± 1.84 y 20.14 ± 1.40% p/p, respectivamente) fueron los componentes principales. Las acetogeninas también se incorporaron en la matriz de un alimento que contenía carne, el cual se inoculó con Listeria monocytogenes y se almacenó a 20 y 4☌. Las propiedades antimicrobianas de las acetogeninas se compararon con conservadors comerciales (Nisaplin® y Mirenat®) utilizando un panel de ocho bacterias Gram positivas. En este estudio se caracterizó el espectro antimicrobiano de acetogeninas purificadas de la semilla del fruto. monocytogenes completely decreasing initial 3-log inoculum to undetectable levels within 3 h, and maintaining the effect to completion.Įl aguacate contiene derivados lipídicos con propiedades antimicrobianas llamadas acetogeninas. During refrigerated storage (4☌, 72 d), Avosafe® inhibited L. Acetogenins’ inhibition zones were 2–4 times higher compared to Nisaplin® and Mirenat® for Gram-positive bacteria, except for Staphylococcus aureus. 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.
