Ultrasound, alone or in combination with natural antimicrobials, is a novel food processing technology of interest to replace traditional decontamination methods, as it milder than classical sterilisation (heat treatment) and maintains desirable sensory characteristics. However, ultrasound efficacy can be affected by structure/composition, well the order which combined treatments are applied. More specifically, target different cell components could result enhanced inactivation if applied...
Abstract Natural antimicrobials are of interest to replace traditional food decontamination methods: they milder and maintain desirable sensory characteristics. However, efficacy can be affected by structure/composition, thus structural effects in a co‐culture pathogen/microflora system investigated. Listeria was grown planktonically (liquid broth) or on biphasic viscoelastic system, monoculture with/without artificial nisin, with Lactococcus lactis (nisin/non‐nisin producing). Microbial...
The aim of the current study is to develop and characterise novel complex multi-phase in vitro 3D models, for advanced microbiological studies. More specifically, we enriched our previously developed bi-phasic polysaccharide (Xanthan Gum)/protein (Whey Protein) model with a fat phase (Sunflower Oil) at various concentrations, i.e., 10%, 20%, 40% 60% (v/v), better mimicry structural biochemical composition real food products. Rheological, textural, physicochemical analysis as well microscopy...
Detection of Listeria by capture on antibody‐coated magnetic beads has been shown to decrease test time and improve sensitivity, relative cultural methods, in a study spiked environmental samples (Mitchell et al. 1993). In this study, immunomagnetic was compared standard methods for detection broad range naturally contaminated food samples. Immunomagnetic at least as sensitive seafood, meats, dairy foods, It possible determine the number present sample, because carried out directly from...
