Legacy and Emerging Contaminants in Demersal Fish Species from Southern Norway and Implications for Food Safety

2020

The present study aimed at measuring the levels of legacy and emerging contaminants in fillet samples from four demersal fish caught in two fishing sites from Southern Norway, in order to assess possible implications for food safety. Levels of organochlorine compounds (OCs), organophosphate pesticides (OPs), polychlorinated biphenyls (PCBs), polybromodiphenyl ethers (PBDE), per- and polyfluoroalkyl substances (PFASs), and polycyclic aromatic hydrocarbons (PAHs) were measured in fillet from Atlantic cod (Gadus morhua), European plaice (Pleuronectes platessa), lemon sole (Microstomus kitt), and European flounder (Platichthys flesus) specimens. A negligible contamination by all the investigate…

Microbiological characterization of the biofilms of wooden shelves used for ripening of traditional raw milk cheeses produced in Sicily (South Italy).

The production of artisanal Sicilian cheeses is generally carried out with wooden equipment. For centuries, wood has been the main material used in cheese making due to its availability, low cost and resistance over time. Among dairy wooden equipment, the wooden vat used for milk curdling plays a role of paramount importance to inoculate the bulk milk with desired lactic acid bacteria (LAB) responsible for the acidification of the curd. In the last few years, the biofilms associated to these containers have been object of study of different research groups, mainly Italian and French, but so far, very little is known about the microbiological characteristics of the wooden shelves used for ch…

Food-Based Dietary Guidelines around the World: A Comparative Analysis to Update AESAN Scientific Committee Dietary Recommendations

2021

Food-Based Dietary Guidelines (FBDG) include dietary recommendations based on food groups according to the general and accepted nutrition principles and current scientific evidence. Adoption of FBDG contributes to the prevention of malnutrition in all its forms, promotes human health, and reduces environmental impact. The present review aims to perform an international comparative analysis of the FBDG adopted in different countries from three different continents (America, Asia, and Europe), with particular reference to the Spanish Food Safety and Nutrition Agency (AESAN, Agencia Española de Seguridad Alimentaria y Nutrición) Scientific Committee dietary recommendations. A total of twelve c…

Application of bacteriocins in vegetable food biopreservation.

2007

Bacteriocins are generally recognized as "natural" compounds able to influence the safety and quality of foods. In the past years, a lot of works have been aimed to the detection, purification and characterisation of bacteriocins, as well as to their use in food preservation strategies. A list of review articles dealing with the application of bacteriocins to the protection of foods of animal origin is also available in literature, but it lacks for a summary on the utilization of bacteriocins in vegetable foods. These biopreservatives can be used in a number of ways in food systems and this paper mainly focuses on the state-of-the-art application of bacteriocins from lactic acid bacteria (L…

TiO2 in the food industry and cosmetics

2021

Abstract The white pigment titanium dioxide is widely used in foodstuff and cosmetics mainly because it provides whitening effect, it acts as a physical filter in sunscreen products, and due to its photocatalytic properties. As food additive, it is labeled as E171 (Europe) and INS171 (United States), and its use was approved in 1966 by the US Food and Drug Administration and in 1969 by the European Union. According to a request of the European Commission, a scientific reevaluation of the safety of TiO2 when used as food additive was recently elaborated by European Food Safety Authority ANS panel. The TiO2 photocatalytic inactivation power is widely studied in order to nonthermally decontami…

Determining nanomaterials in food

2011

Abstract Nanotechnology has emerged as one of the most innovative technologies and has the potential to improve food quality and safety. However, there are a few studies demonstrating that nanomaterials (NMs) are not inherently benign. This review highlights some current applications of NMs in food, food additives and food-contact materials, and reviews analytical approaches suitable to address food-safety issues related to nanotechnology. We start with a preliminary discussion on the current regulatory situation with respect to nanotechnology in relation to foods. We cover sample preparation, imaging techniques (e.g., electron microscopy, scanning electron microscopy and X-ray microscopy),…

Bioaccesibility of Cylindrospermopsin from cooked fish muscle after the application of an in vitro digestion model and its bioavailability.

2017

Humans can be exposed to cyanotoxins through the ingestion of contaminated water, food or beverages. In the present work, the bioaccesibility of Cylindrospermopsin (CYN), one of the most relevant cyanotoxins, was evaluated in a pure CYN solution and cooked CYN-contaminated fish muscles (20 μg/mL). An in vitro digestion model including the salivar, gastric, duodenal and colonic phases was performed, being each fraction analyzed by HPLC-MS-MS to evaluate CYN degradation. Moreover, Caco-2/TC7 cells were exposed to the digested duodenal and colonic phases to elucidate the final bioavailability of CYN in an approximation to the real human exposure scenario. The results revealed that CYN bioacces…
