[Ab] Resumo:The lipid characterization of storage fat, subcutaneous fat and bone marrow, originated from three different bovine categories, calf, young bull and cow, was carried out in order to develop a re-use of these by-products. After the lipid extraction, the compositions in fatty acids, triacylglycerols and cholesterol were determined by GC-FID. A total of 25 fatty acids were identified in all by-products; the oleic acid was the preponderant component, followed by palmitic, stearic, palmitoleic, linoleic and myristic acid. The long chain triacylglycerols (T48, T50 and T52) were the main products, especially in the cow's by-products. The subcutaneous fat of all animals showed the highest cholesterol content, whereas it was present in low amount in the others. Phospholipids were analysed in bone marrow of all the animals and phosphatidylcholine was the most abundant compound. Because of the high fat content and essential fatty acids and the low cholesterol amount, storage fat and bone marrow could represent a valuable lipid resource in food and pharmaceutical industry.

[Ab] Resumo:A rapid, simple, and sensitive fluorescent immunochromatographic strip test (ICST) based on quantum dots (QDs) has been developed to detect 1-aminohydantoin (AHD), a major metabolite of nitrofurantoin in animal tissues. To achieve this, QD-labeled antibody conjugates, which consist of CdSe/ZnS QDs and monoclonal antibodies, were prepared by an activated ester method. Under optimal conditions, with the nitrophenyl derivative of AHD as the target, the ICST had a linear range from 0.1 to 100 ng/mL, with a correlation coefficient of 0.9656 and a 50% inhibitory concentration of 4.51 ng/mL. The limit of detection was 0.14 ng/g, which was below the minimum required performance limit of 1 µg/kg for AHD established by the European Commission. The recoveries for AHD ranged from 81.5% to 108.2%, with coefficients of variation below 13%, based on intraday and interday analysis. Furthermore, for AHD in real samples, the ICST showed high reliability and high correlation with liquid chromatography-tandem mass spectrometry (correlation coefficient of 0.9916). To the best of our knowledge, this is the first report of a novel and sensitive method based on a fluorescent ICST to detect AHD below the minimum required performance limit. The ICST demonstrated high reliability, and could be ideally suited for rapid, simple, and on-site screening of AHD contamination in animal tissues.

[Ab] Resumo:Background: Rice is a staple food for many people in the world and an important ingredient for production of food for infants and young children. According to European Food Safety Authority (EFSA), cereals, primarily rice and rice products, are an important source of human exposure to inorganic arsenic, which has been classified by the International Agency for Research on Cancer (IARC) as group I carcinogen. Arsenic is present in rice and rice products mainly as an inorganic form being more toxic than organic compounds Objectives: The aim of the study was to determine the total and inorganic arsenic content in rice, rice-based products including food for infants and young children available on the market in Poland and thus to estimate consumer exposure to inorganic arsenic from these groups of foodstuffs Materials and Methods: A total of 62 samples of rice and rice products from trade, including a group of rice products for infants and young children, were tested. Contents of total and inorganic arsenic were determined by using hydride generation atomic absorption spectrometry (HGAAS), after dry mineralization of samples and reduction of arsenic to arsenic hydride with sodium borohydride. To extract the inorganic arsenic forms, the samples were subjected to hydrolysis in concentrated HCl and then reduced in the presence of hydrobromic acid and hydrazine sulphate after which triple chloroform extractions and triple 1M HCl re-extractions were performed. Exposure of different groups of populations (adults and children), was estimated in relation to the Benchmark Dose Lower Confidence Limit (BMDL05) as set by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) that resulted in a 0.5% increase in lung cancer (3.0 µg/kg body weight (b.w.) per day) Results: Mean content of total and inorganic arsenic in investigated rice samples was 0.12 mg/kg (median: 0.09 mg/kg; 90th percentile 0.22 mg/kg) and 0.04 mg/kg (median: 0.03 mg/kg, 90th percentile 0.07 mg/kg). Brown rice was found to be more highly contaminated with both total and inorganic arsenic than white rice. Mean contamination of brown rice with total arsenic and inorganic arsenic was: 0.18 mg/kg (median: 0.12 mg/kg, 90th percentile: 0.32 mg/kg) and 0.05 mg/kg (median: 0.05 mg/kg, 90th percentile: 0.07 mg/kg). In turn for the white rice contamination was lower, mean total arsenic content: 0.10 mg/kg (median: 0.08 mg/kg, 90th percentile: 0.19 mg/kg) and mean inorganic arsenic: 0.03 mg/kg (median: 0.03 mg/kg, 90th percentile: 0.06 mg/kg). Contamination of rice-based products both total and inorganic arsenic was similar to those reported for rice, except rice wafers (mean: 0.24 mg/kg and 0.13 mg/kg). In the group of products for infants and young children obtained results were low ­ mean total arsenic content was 0.06 mg/kg and inorganic arsenic 0.02 mg/kg. The estimated average adult and children's exposure to inorganic arsenic with rice and rice products was less than 1% of the BMDL05. Intake of inorganic arsenic by 12-month-old infants with ricebased products intended for this group of population was at 6% BMDL05 Conclusions: Based on the obtained results, it was found that the content of total and inorganic arsenic in investigated samples of rice and rice products did not pose a health risk even though contamination levels in some individual samples were significant

[Ti] Título:SANIST: optimization of a technology for compound identification based on the European Union directive with applications in forensic, pharmaceutical and food analyses.

[Ab] Resumo:Electrospray Ionization and collision induced dissociation tandem mass spectrometry are usually employed to obtain compound identification through a mass spectra match. Different algorithms have been developed for this purpose (for example the nist match algorithm). These approaches compare the tandem mass spectra of the unknown analyte with the tandem mass spectra spectra of known compounds inserted in a database. The compounds are usually identified on the basis of spectral match value associated with a probability of recognition. However, this approach is not usually applied to multiple reaction monitoring transition spectra achieved by means of triple quadrupole apparatus, mainly due to the lack of a transition spectra database. The Surface Activated Chemical Ionization-Electrospray-NIST Bayesian model database search (SANIST) platform has been recently developed for new potential metabolite biomarker discovery, to confirm their identity and to use them for clinical and diagnostic applications. Here, we present an improved version of the SANIST platform that extends its application to forensic, pharmaceutical, and food analysis studies, where the compound identification rules are strict. The European Union (EU) has set directives for compound identification (EU directive 2002/657/EC). We have applied the SANIST method to identification of 11-nor-9-carboxytetrahydro-cannabinol in urine samples (an example of a forensic application), circulating levels of the immunosuppressive drug tacrolimus in blood (an example of a pharmaceutical application) and glyphosate in fruit juice (an example of a food analysis application) that meet the EU directive requirements.

[Ab] Resumo:Phospholipids are an important class of lipids in cell membranes and food. Several high-performance liquid chromatography (HPLC) methods have been developed to analyze phospholipids at the molecular species level. We developed a two-dimensional HPLC system with a charged aerosol detector and mass spectrometry (MS) to analyze phosphatidylethanolamine (PE), phosphatidylcholine (PC), and their plasmalogens (pls) extracted from food materials. Accordingly, the phospholipid molecular species can be analyzed in a single step despite using smaller samples. We confirmed that chromatogram peaks from soybean lecithin are mostly baseline separated, assigned, and quantified (24 molecular species for PE and 27 for PC). In addition, it was confirmed that chromatograms of lipids extracted from chicken breast meat include plasmalogen peaks. The PE fraction in lipids extracted from chicken breast meat contained 17 types of ethanolamine plasmalogens, corresponding to approximately 57% of the total by weight. The PC fraction contained only four choline plasmalogens, corresponding to approximately 11% of the total weight. The composition of the pls-PC molecular species differed from that of pls-PEs. The polyunsaturated fatty acids connected at the sn-2 positions of the pls-PEs consisted of 20.5% 20:4 fatty acid and were independent of the carbon chain at the sn-1 position. However, the 18:1 fatty acid at the sn-2 position was dependent on the carbon chain at the sn-1 position.

[Ab] Resumo:One of the main problems of nutrition of children and adolescents is to assess chemical contamination of baby food products and the establishment of the relation with the health of the child population. With the entering different chemical compounds in the body of the child there can be observed disorders of the nervous, urinary, cardiovascular system, gastrointestinal tract, as well as metabolic deteriorations, degenerative processes in parenchymal organs and bone destruction. The aim of the study was to analyze data on chemical contamination of baby food products in the Russian Federation for 2012-2014. The analysis was executed on the data of Federal Information Fund of social and hygienic monitoring of the Russian Federation. There were identified priority pollutants (toxic elements, nitrites, nitrates, nitrosamines, pesticides, hydroxymethylfurfural, mycotoxins) and risk areas (the Lipetsk region, the Krasnodar Territory, the Republic of Adygea, city of Moscow, Tatarstan, the Kabardino-Balkar Republic, the Ryazan region). There are detected contamination levels not exceeding MAC (in the dynamics of the three years offollow up, on average 22%), requiring their hygienic assessment. There were determined the baby food products containing most common occurred chemical contaminants: fruits and vegetables products, canned products, canned meat, cereals, dairy products, liquid and adapted and partially adapted milk formalas. Identified data indicate to a need for further studies of chemical substances in products for children's nutrition in order to establish the causal relationships with a various diseases and the substantiation of methodological approaches to the risk assessment of combined exposure to chemical contaminants in concentrations up to the MPC on health of children, including infants.

[Ab] Resumo:The aim of this study was to define the composition of microbiota and the volatile organic compounds (VOCs) in samples of raw milk collected for 22 months between 2012 and 2014 originated from north-eastern region of Poland. The results revealed that the VOCs profile changed with respect to the season of milk collection, and milk collected in autumn was characterized by a higher content of acetic acid (C2), propionic acid (C3) and valeric acid (C5), whereas spring was characterized by a frequent presence of acetone (Ac), ethanol (Et) and ethyl acetate (EtAc). Bacterial species composition changed considerably within the tested period and some bacterial species/groups occurred seasonally, e.g. L. helveticus (summer), L. casei (winter). The results show usefulness of the applied techniques (PCR-DGGE and HS-GC) and data analysis (PCA, correlation coefficients) methods in characterizing the raw milk quality intended for dairy production.

[Ab] Resumo:A multiresidue method has been developed for the determination of emerging pollutants in leafy and root vegetables. Selected compounds were 6 perfluoroalkyl compounds (5 perfluorocarboxylic acids and perfluorooctanesulfonic acid), 3 non-ionic surfactants (nonylphenol and nonylphenolethoxylates), 8 anionic surfactants (4 alkylsulfates and 4 linear alkylbenzene sulfonates), 4 preservatives (parabens), 2 biocides (triclosan and triclocarban), 2 plasticizers (bisphenol A and di-(2-ethylhexyl)phthalate), 6 UV-filters (benzophenones) and 4 hormones. The method is based on ultrasound-assisted extraction, clean-up by dispersive solid-phase extraction (d-SPE) and liquid chromatography-tandem mass spectrometry analysis. Due to the diversity of the physico-chemical properties of the target compounds, and to better evaluate the influence of sample treatment variables in extraction efficiencies, Box-Behnken design was applied to optimize extraction solvent volume, number of extraction cycles and d-SPE sorbent amount. Linearity (R ) higher than 0.992, accuracy (expressed as relative recoveries) in the range from 81 to 126%, precision (expressed as relative standard deviation) lower than 19% and limits of detection between 0.025 and 12.5ngg dry weight were achieved. The method was applied to leafy vegetables (lettuce, spinach and chard) and root vegetables (carrot, turnip and potato) from a local market. The highest concentrations corresponded to the surfactants reaching levels up to 114ngg (dry weight), in one of the lettuce samples analyzed.
