Extending the shelf-life of live clams, Venerupis corrugata - important aspects...

Venerupis corrugata (pullet carpet shell) is a premium native clam species in Portugal. This species is highly perishable, typically sold live within 3 or 4 days, posing a significant risk of loss. Therefore, efforts to extend its shelf-life are relevant. The impact of the storage temperature (3, 5, 8 and 12 °C) on clams in plastic net bags and the effect of modified atmosphere packaging (MAP) were investigated...

Microbiological profile of vegan and vegetarian meat analogues from the Portugu...

Motivation: Meat analogues, especially those of plant origin, are generally high in protein, high in water activity (aw > 0.95) and have a mildly acidic pH (pH > 5.5) (Kabisch et al., 2024), making these products highly susceptible to microbial spoilage. With the current increase in consumption of meat analogues, their food safety aspects need to be considered and the question arises: can meat analogs pose a fo...

Preparation and characterization of bioactive chitosan-based films incorporated...

Chitosan films with olive leaf extract (OLE) incorporated at different concentrations were characterized regarding their antimicrobial, antioxidant and some relevant physical properties (i.e., solubility, water vapor permeability, and tensile properties). Results indicate that the active films have substantial antimicrobial activity against Listeria monocytogenes and Campylobacter jejuni mostly extending the mi...

Traditional methods of analysis for Listeria monocytogenes

Conventional methods for the detection of Listeria monocytogenes in foods and environmental samples rely on selective pre-enrichment, enrichment, and plating. This is followed by confirmation of suspected colonies by testing a limited number of biochemical markers.

Un nuevo ejemplar de cantimplora en Terra Sigillata Hispánica localizada en Aug...

Se presenta una cantimplora manufacturada en terra sigillata hispánica. Esta pieza fue hallada en una intervención arqueológica desarrollada en la Casa del Mitreo (Mérida, Badajoz) en el año 1994. Espacialmente, fue localizada en una estancia contigua al atrium de la domus, es decir, en un contexto de carácter doméstico, sin embargo, no contamos con datos estratigráicos que nos aporten novedades de tipo cronoló...
