UNLABELLED Antimicrobial peptides offer potential as novel therapeutics to combat food spoilage and poisoning caused by pathogenic and nonpathogenic bacteria. Our previous studies identified the peptide human beta-defensin 3 (HBD3) as a potent antimicrobial agent against a wide range of beer-spoiling bacteria. Thus, HBD3 is an excellent candidate for development as an additive to prevent food a...

Cold-smoked salmon is a lightly preserved fish product in which a mixed microbial flora develops during storage and where the interactive behaviour of micro-organisms may contribute to their growth and spoilage activity. The aim of this study was to assess the effect of the bacterial interactions between the main species contaminating the cold-smoked salmon on bacterial growth, chemical and sen...

Microbial spoilage is one of the main factors affecting the quality of fresh fruits and vegetables, leading to off-flavor, fermented aroma, and tissue decay. The knowledge of microbial growth kinetics is essential for estimating a correct risk assessment associated with consuming raw vegetables and better managing the development of spoilage microorganisms. This study shows, for the first time,...

Human milk is the biological norm for newborn nutrition, with breast from mother being recognized as best source of nutrition infant health. When mother’s unavailable, donor human alternative infants low birthweights. Growing recognition benefits has led to increasing global interest in monitoring and controlling milk’s quality fulfil need milk. In response this need, REAMIT project proposed ad...

Considerable salt-soluble protein degradation was observed in pork muscle inoculated with Pseudomonas fragi. During a 20-day incubation period at 10 C, the samples proceeded to rank spoilage or putrefaction. There was a large decrease in the salt-soluble protein fraction and a corresponding increase in nonprotein nitrogen. Disc gel electrophoretic patterns showed that breakdown of the salt-solu...

The microorganisms most commonly involved in meat spoilage are Pseudomonas spp., the Enterobacteriaceae family, lactic acid bacteria and the Brochothrix thermosphacta. The factors that are considered to have the main effect on the speed of spoilage and the shelf life of fresh meat are intrinsic factors (initial number of psychrotrophs present on the meat surface, water activity, the pH value an...

Bacteria are part of the natural microbial ecosystem of wine and play an important role in winemaking by reducing wine acidity and contributing to aroma and flavour. Conversely, they can cause numerous unwelcome wine spoilage problems, which reduce wine quality and value. Lactic acid bacteria, especially Oenococcus oeni, contribute positively to wine sensory characters, but other species, such ...

The objective of this study was to investigate the adhesion of isolated spoilage bacteria to packaging materials used in the food industry. Microorganisms were isolated from commercial fruit-flavored mineral water in plastic bottles with flocks as a visual defect. The Gram-negative rods were identified using the molecular method through the amplification of a partial region of the 16S rRNA gene...
