High pressure treatment and green tea extract synergistically control enteric virus contamination in beverages
2022
Consumers are driving food production toward the use of natural preservatives and minimal processing technologies. Green tea extract (GTE) at low concentration could be combined with high pressure processing (HPP) for reduced treatment times and quality impact on foods in a hurdle concept for synergistic effects on foodborne viral pathogens, specifically human norovirus and hepatitis A virus (HAV). Viral inactivation by HPP (at 300, 400, and 500 MPa for 5 min) combined with 3.3 mg/mL aged-GTE was initially evaluated in buffer (PBS) against murine norovirus (MNV), a culturable human norovirus surrogate, and HAV. Furthermore, human norovirus inactivation was evaluated by the novel human intes…
Security Standards Applied to Drinking Water
2021
This chapter presents security standards as applied to drinking water, based on the assumption that freshwater sources face huge threats for humankind both qualitatively and quantitatively due to uncertain global changes, namely population growth, rapid urbanization, and climate change. The study investigates whether the International Featured Standards (IFS—Food), which are complementary to HACCP (Hazard analysis and critical control point), can be used as a system of indicators to measure water security. The case study focuses on bottled water, by identifying structural and contingent risk factors for water as essential food and investigates the suitability of the IFS instrument as an ind…
Genome Sequence of Lactobacillus plantarum 19L3, a Strain Proposed as a Starter Culture for Slovenská Bryndza Ovine Cheese
2014
ABSTRACT The genome sequence of Lactobacillus plantarum isolated from ovine cheese is presented here. This bacterium is proposed as a starter strain, named 19L3, for Slovenská bryndza cheese, a traditional Slovak cheese fulfilling European Food Safety Authority (EFSA) requirements.
Comparative efficacy of Zataria multiflora Boiss., Origanum compactum and Eugenia caryophyllus essential oils against E. coli O157:H7, feline caliciv…
2013
Abstract Ready-to-eat salads using baby-leaf and multi-leaf mixes are one of the most promising developments in the fresh-cut food industry. There is great interest in developing novel decontamination treatments, which are both safe for consumers and more efficient against foodborne pathogens. In this study, emulsions of essential oils (EOs) from Origanum compactum (oregano), Eugenia caryophyllus (clove), and Zataria multiflora Boiss (zataria) were applied by spray (0.8 ml) after the sanitizing washing step. The aim was to investigate their ability to control the growth of potentially cross-contaminating pathogens and endogenous microbiota in commercial baby leaves, processed in a fresh-cut…

Guidance on allergenicity assessment of genetically modified plants
2017
Abstract This document provides supplementary guidance on specific topics for the allergenicity risk assessment of genetically modified plants. In particular, it supplements general recommendations outlined in previous EFSA GMO Panel guidelines and Implementing Regulation (EU) No 503/2013. The topics addressed are non‐IgE‐mediated adverse immune reactions to foods, in vitro protein digestibility tests and endogenous allergenicity. New scientific and regulatory developments regarding these three topics are described in this document. Considerations on the practical implementation of those developments in the risk assessment of genetically modified plants are discussed and recommended, where …
Stochastic model for a biological complex system: analysis of the bacterial growth in food products
2012
The Physics of Complex Systems has recently taken a more and more important role in the description of natural systems because of the interactions, both deterministic and noisy, between such systems and the environment. In particular the noise plays a relevant role in biological systems, whose dynamics is strongly influenced by environmental variables subject to random fluctuations. In this work a stochastic model is exploited to reproduce the growth of bacteria in food of animal origin. Specifically the dynamics of a bacterial species, Listeria monocytogenes, is analyzed in the presence of lactic acid bacteria (LAB) during the period of the fermentation of meat products. The model, based o…
An Integrated Approach to Mandarin Processing: Food Safety and Nutritional Quality, Consumer Preference, and Nutrient Bioaccessibility
2017
Mandarins are a member of the Citrus genus and are the focus of growing commercial interest, with satsuma mandarins (Citrus unshiu) and the common mandarin (Citrus reticulata Blanco) being the most important mandarin varieties. The possible health benefits and functional properties of those fruits are often associated with the antioxidative function of vitamin C, carotenoids, and phenolic compounds. While most mandarins are consumed fresh, many are processed into juices (mostly cloudy), usually via thermal processing which can lead to the creation of off-flavors and may diminish nutritional quality. The aim of this review is to summarize the most significant and recent information on the sa…
Comparison of the Antibiotic-Resistant <i>Enterobacteriaceae</i> Content in Conventional, Organic and Fresh-Cut Vegetables Sold in Valenc…
2020
Bacterial content of fresh vegetables that are often eaten raw represents a risk factor for consumers, and the presence in these produce of antibiotic-resistant bacteria constitutes an additional food safety concern. We have compared the Enterobacteriaceae content, as well as the antibiotic resistances of bacterial isolates, in samples of different types of fresh vegetables (conventional an organic produce, fresh-cut vegetables and prepared salads) marketed in Valencia (Spain) in order to find possible differences among these vegetable types. Bacterial isolation, identification and resistance assays to eleven relevant chemotherapeutics agents were performed according to standard microbiolog…
[Loyauté des transactions sur un marché relatif aux attributs de croyance : une analyse appliquée aux produits agro-alimentaires]
2001
International audience; Après avoir décliné la typologie des caractéristiques des produits en termes d'attributs de recherche, d'expérience et de croyance, les auteurs soulignent les mécanismes susceptibles d'assurer l'efficacité des transactions marchandes. Afin de cerner les enjeux liés à la loyauté des transactions dans le cas des attributs de croyance, ils montrent à l'aide d'un jeu simple, le caractère crucial des phases de définition, de vérification et de signalement, ces dernières nécessitant généralement l'intervention d'agents extérieurs à la transaction marchande.
