A simple and reliable multiresidue method for quantitative determination of veterinary drugs in bovine muscle and milk using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) was developed. Critical MS parameters such as capillary voltage, cone voltage, collision energy, desolvation gas temperature, and extraction mass window were carefully optimised to obtain the best possible sensitivity. Analytical samples were prepared using extraction with acetonitrile and hexane in the presence of anhydrous sodium sulphate and acetic acid, followed by ODS cartridge clean-up...

Recently, traces of brominated flame retardants (BFRs) have been detected in black plastic food contact materials (FCMs) indicating the presence of recycled plastics, mainly coming from waste electric and electronic equipment (WEEE) as BFRs are one of the main additives in electric applications. In order to evaluate efficiently and preliminary in situ the presence of WEEE in plastic FCMs, a generic procedure for evaluation of WEEE presence in plastic FCMs by using defined parameters having each an associated importance level has been proposed...

Contaminants in food packaging are a challenge of our time since the packaging material itself has been found to represent a source of food contamination through the migration of substances from the packaging. Before first use, packaging materials destined for the packaging of dry foods can be evaluated by performing migration experiments with the simulant for dry foods: Tenax(®). This simulant is commercially available as a powder that is more difficult to handle during the migration experiments. In this paper we report the development of a Tenax(®) film...

This paper reports the first application and benefits of ion mobility in combination with liquid chromatography and a transportable time-of-flight mass spectrometer to the analysis of monochloropropane-diol esters (MCPDE) in vegetable oils. The additional selectivity obtained with the ion mobility allowed the quantitative analysis of MCPDEs as such in their intact form (direct analysis) without any chemical derivatization and furthermore without any enrichment or purification step. This gain in selectivity manifests primarily in the resolution of interferences originating for example from the diacylglycerol components of palm oil...

A gas-chromatographic single quadrupole analytical method for the analysis of the sixteen priority EU polycyclic aromatic hydrocarbons (PAHs) in food is presented in this paper. The method fulfils the request of Regulation EU 836/2011 for an analytical procedure to be used for official control of PAHs in food, in EU member states. The sample preparation involves a Pressurised Liquid Extraction (PLE) with an in-cell clean-up step followed by a lipid removal using SPE on a styrene divinylbenzene stationary phase (SDVB) and a final gel permeation chromatography (GPC) step...

The methodology to electrospin polystyrene (PS) fibers functionalized with the inclusion complex between 1-methylcyclopropene and α-cyclodextrin (α-CD) has been developed successfully. Due to limited availability, α-CD crystals instead of 1-MCP/α-CD complex were suspended in the electrospinning (ES) solutions to investigate the electrospinning process. The ES solutions were characterized in terms of viscosity, conductivity and surface tension. Meanwhile the fibers were subjected to scanning electron microscopy...

The use of alternative feed ingredients in farm animal's diets can be an interesting choice from several standpoints, including safety. In this respect, the aim of this study was to investigate the safety features of selected Former Food Products (FFPs) intended for animal nutrition produced in the framework of IZS PLV 06/14 RC project by a FFP processing plant. Six FFP samples, both mash and pelleted, were analysed for the enumeration of Total Viable Count (TVC) (ISO 4833), Enterobacteriaceae (ISO 21528-1), Escherichia coli (ISO 16649-1), coagulase-positive Staphylococci (CPS) (ISO 6888), presumptive B...

Due to the internationalization of food production and distribution, there has been a significant increase of food fraud in recent years. Food fraud can have serious health implications, and occurs when food manufacturers implement unethical practices such as making false label claims as well as using additives and fillers within their products to increase profitability. This has been a serious concern. Meat adulteration was examined using a well-defined proteogenomic annotation, carefully selected surrogate tryptic peptides and high-resolution mass spectrometry...

Many multiresidue methods for the determination of pesticides in vegetables and fruits have been reported to date. However, few such methods have been employed to investigate pesticide residues in animal tissue. In this study, an LC-MS/MS multiresidue method coupled with modified QuEChERS extraction was developed and validated for the investigation of eight pesticide residues: prallethrin (PR), resmethrin (RMT), imidacloprid (IMC), diflubenzuron (DFB), cyromazine (CYR), etofenprox (EFP), dinotefuran (DNT) and phthalthrin (PTLT)...

The core-food (CF) approach, first adopted in the United States in the 1980s, has been widely used by many countries to assess the exposure to dietary hazards at a population level. However, the reliability of exposure estimates (C × CR) depends critically on sampling methods designed for the detected chemical concentrations (C) of each CF to match with the corresponding consumption rate (CR) estimated from the surveyed intake data. In order to reduce the uncertainty of food matching, this study presents a sampling design scheme, namely the subsample method, for the 2016 Taiwan total diet study (TDS) on veterinary drugs...

Post-smolt Atlantic salmon, were fed standard feed with added 2 or 6 mg/kg pure deoxynivalenol (DON), 0.8 or 2.4 mg/kg pure ochratoxin A (OTA), or no added toxins, for up to eight weeks. The experiments were performed in duplicate tanks with 25 fish each per diet group, and the feed was given for three two-hour periods per day. After three, six and eight weeks ten fish from each diet group were sampled. In the following hours after the last feeding at eight weeks, toxin elimination was studied by sampling three fish per diet group at five time points...

Post-consumer recycled (PCR) plastic material is made by collecting used plastic products (e.g., bottles and other plastic packaging materials) and re-processing them into solid-state pellets or flakes. Plastic recycling has positive environmental benefits, but may also carry potential drawbacks due to unwanted organic and inorganic contaminants. These contaminants can migrate into food packaging made from these recycled plastic materials. The purpose of this research was to identify economically viable real-time monitoring technologies that can be used during conversion of virgin and recycled resin feedstocks (i...

The aim of the study was the development of a multi-functional, high-performance, fully biodegradable multi-layer polylactic acid (PLA) film for food packaging applications. In particular, sealable multi-layer PLA/clay nanocomposite systems with different layouts in terms of composition and relative thickness of the layers, all consisting of a PLA/clay nanocomposite layer between two pure PLA layers for direct food contact, were designed and produced by blown film co-extrusion. The films which were obtained were analysed for their morphology, functional properties and lactic acid specific migration in 50% ethanol...

Carotenoids are used in animal nutrition mainly as sensory additives that favourably affect the colour of fish, birds and food of animal origin. Various analytical methods exist for their quantification in compound feed, reflecting the different physico-chemical characteristics of the carotenoid and the corresponding feed additives. They may be natural products or specific formulations containing the target carotenoids produced by chemical synthesis. In this study a multi-analyte method was developed that can be applied to the determination of all 10 carotenoids currently authorised within the European Union for compound feedingstuffs...

Optimising supply chain management can help to reduce food waste. This paper describes how intelligent packaging can be used to reduce food waste when used in supply chain management based on quality-controlled logistics (QCL). Intelligent packaging senses compounds in the package that correlate with the critical quality attribute of a food product. The information on the quality of each individual packaged food item that is provided by the intelligent packaging can be used for QCL. In a conceptual approach it is explained that monitoring food quality by intelligent packaging sensors makes it possible to obtain information about the variation in the quality of foods and to use a dynamic expiration date (IP-DED) on a food package...

Printing inks are commonly used in multilayer plastics materials used for food packaging and compounds present in inks can migrate to the food either by diffusion through the multilayers or because of set-off phenomena. To avoid this problem the right design of the packaging is crucial. In this work, the safety by design of multilayer materials has been studied. First, the migration from 4 different multilayers manufactured using polyethylene terephthalate (PET), aluminium (Al) and polyethylene (PE) was determined...

Insects are rich in proteins and could be an alternative source of proteins to feed animals and humans. Numerous companies have started the production of insects for feed purposes. In Europe, these processed animal proteins are not yet authorized by legislation, as many questions still need to be answered concerning this "novel food". Authorizations will be possible when methods of authentication of the products are available. In this study we propose real-time PCR methods for the specific detection of the mealworm (Tenebrio molitor), one of the most widely used insects for food and feed production...

Polyethylene terephthalate is increasingly used as food contact material for example in containers for beverage such as bottles for soft drinks, mineral water, juices and beer. Mass transport of substances present in packaging materials into the packed food and beverages is monitored to verify the food law compliance of the materials. PET is known to contain or give rise to migrants that are oligomers derived from the polymeric material. Until now their actual migration potential has been investigated only poorly...

Bone fragments are essential structures for the detection of processed animal proteins (PAPs) in feed by light microscopy for official controls according to Annex VI of European Union Regulation EC/152/2009. The preparation of samples submitted for analysis requires a grinding step to make them suitable for microscopic slide preparation and observation. However, there are no technical guidelines set down for this step despite the fact that it can lead to an increase in bone numbers due to fragmentation. This was demonstrated by an in-house study carried out by the Irish National Reference Laboratory (NRL) for animal protein detection...

A refined exposure assessment was undertaken to calculate the estimated daily intake (EDI) of the seven FD&C straight-colour additives and five FD&C colour lakes ('synthetic' food colours) approved in the United States. The EDIs were calculated for the US population as a whole and specific age groups, including children aged 2-5 and 6-12 years, adolescents aged 13-18 years, and adults aged 19 or more y. Actual use data were collected from an industry survey of companies that are users of these colour additives in a variety of products, with additional input from food colour manufacturers...
