High-pressure processing and antimicrobial biodegradable packaging to control Listeria monocytogenes during storage of cooked ham.

Combined effect of natural antimicrobials and high pressure processing to prevent Listeria monocytogenes growth after a cold chain break during storage of cooked ham

The control of Clostridium botulinum during extended storage of pressure-treated, cooked chicken

High pressure processing (HPP) is used as a post-process decontamination treatment to ensure that cooked chicken is free from Listeria monocytogenes and other food poisoning bacteria. However HPP does not inactivate bacterial endospores and the conditions in cooked chicken could support the growth of Clostridium botulinum. Therefore some method for controlling the germination of spores and thei...

Analysing and modelling the growth behaviour of Listeria monocytogenes on RTE cooked meat products after a high pressure treatment at 400 MPa.

Various predictive models are available for high pressure inactivation of Listeria monocytogenes in food, but currently available models do not consider the growth kinetics of surviving cells during the subsequent storage of products. Therefore, we characterised the growth of L. monocytogenes in sliced cooked meat products after a pressurization treatment. Two inoculum levels (10(7) or 10(4) CF...

Microbial inactivation after high-pressure processing at 600 MPa in commercial meat products over its shelf life

The behaviour of spoilage and pathogenic microorganisms was evaluated after high-pressure treatment (600 MPa 6 min, 31 8C) and during chilled storage at 4 8C for up to 120 days of commercial meat products. The objective was to determine if this pressure treatment is a valid process to reduce the safety risks associated with Salmonella and Listeria monocytogenes, and if it effectively avoids or ...

Antimicrobial Efficacy of Alpinia galanga (Linn.) Swartz Flower Extract Against Listeria monocytogenes and Staphylococcus aureus in a Ready-to-Eat Turkey Ham Product

The pH, objective color and antimicrobial efficacy of Alpinia galanga (Linn.) Swartz Flower Extract (GFE) in a ready-to-eat turkey ham product inoculated with Listeria monocytogenes and Staphylococcus aureus were evaluated. Ham treatments included positive control (inoculated with Listeria monocytogenes and Staphylococcus aureus cocktail only), 0.5% GFE incorporated into meat batter prior to co...
