Thirteen individual organochlorine compounds at 3 concentrations (80, 400, and 2000 ng/mL culture medium), as well as mixtures, were assayed for the estrogen receptor (ER) activation or inhibition, using a luciferase reporter gene assay (RGA). None of the PCB 138, 153, or 180 or their mixture induced a response in the RGA. o,p'-DDT was the most potent xenoestrogen fromthe DDT group, inducing a response already at 80 ng/mL. From the HCH and HCB group, only 𝛽-HCH (at 400 and 2000 ng/mL) and 𝛿-HCH (at 2000 ng/mL) displayed estrogenic activities.These 13 organochlorines were determined by GC-MS in 12 samples of North Sea harbor porpoise blubber. The PCBs were the main contaminants. Within each group, PCB 153 (6.0 × 102∼4.2 × 104 𝜇g/kg), p,p'- DDE (5.1 × 102∼8.6 × 103 𝜇g/kg), and HCB (7.6 × 101∼1.5 × 103 𝜇g/kg) were the compounds found in highest concentrations.The hormonal activity of the porpoise blubber samples was also assayed in RGA, where two samples showed estrogenic activity, seven samples showed antiestrogenic activity, and one sample showed both estrogenic and antiestrogenic activity. Our results suggest that the 13 POPs measured by GC-MS in the samples cannot explain alone the estrogenicity of the extracts. [less ▲]

The aim of this study was to compare the effect of aging technique (wet-aging vs. carcass-aging), muscle (longissimus dorsi vs. rectus femoris) and previous vacuum storage time on color and lipid stability of beef packaged in high-oxygen atmosphere. After a seven-day wet- or carcass-aging step, longissimus dorsi and rectus femoris muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. At different times, part of these samples was repackaged under modified atmosphere – 70 % O2:30 % CO2 –, and stored during 7 days at +4 °C. The following parameters were evaluated at different intervals: color (CIE L*a*b*), metmyoglobin %, lipid oxidation (TBARS), antioxidant enzyme activities (catalase, glutathione peroxidase and superoxide dismutase), alpha-tocopherol and fat content. The sensitivity of modified atmosphere repacked meat cuts to oxidation was influenced by the conditions of the previous aging period (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage. Oxidation stability could be associated with catalase activity, and no association could be established with the alpha-tocopherol content. [less ▲]

Two common approaches for beef aging are wet-aging and carcass-aging. Wet-aging refers to meat aged in a sealed vacuum package at refrigerated temperatures, while carcass aged at controlled temperatures and humidity is defined as carcass-aging. Carcass-aging is an ancient process used nowadays to produce beef characterized by its superior quality. The meat conservability is influenced by its sensitivity to oxidative process which can vary from one muscle to another. The aim of this study was to compare the effect of aging technique (wet-aging vs. carcass-aging), muscle (longissimus dorsi vs. rectus femoris) and previous vacuum storage time on colour and lipid stability of beef packaged in high-oxygen atmosphere. After a seven-day wet- or carcass-aging step, longissimus dorsi and rectus femoris muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. At different times, part of these samples was repackaged under modified atmosphere – 70 % O2:30 % CO2 –, and stored during 7 days at +4 °C in order to simulate retail conditions. The following parameters were evaluated: colour (CIE L*a*b*), metmyoglobin %, lipid oxidation (TBARS), antioxidant enzyme activities (catalase, glutathione peroxidase and superoxide dismutase), alpha-tocopherol and fat content. The sensitivity of high-oxygen atmosphere repacked meat cuts to oxidation was influenced by the aging technique (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage. Oxidation stability could be associated with muscle catalase activity, and no association could be established with the alpha-tocopherol content. [less ▲]

This study consists to finalize some technologies for the production of a fermented drink called dèguè. This drink is widely consumed in Benin and other countries in sub-Saharan Africa. Following three different technologies, we had produced three (03) types of dèguè respectively with maize flour, sorghum and millet. These types have been analyzed and their microbiological characteristics were evaluated. The microbiological analysis results obtained from the experiments have shown that lactic acid bacteria, yeasts and molds were the dominant microflora of dèguè and varied respectively 7.22log10UFC/g to 7.55log10UFC/g for lactic acid bacteria and 7.78log10UFC/g to 8.44log10UFC/g for yeasts and molds. Moreover, the statistical analysis of these results showed that there was no significant difference at 5% (p <0.05) between the three types of dèguè. The values of lactic acid bacteria obtained were consistent with the standard (≥ 107/g) attached to the yoghurt. No type contained neither total coliforms nor thermotolerant coliforms. The products (dèguès) were also free of pathogenic microorganisms such as Escherichia coli, Staphylococcus aureus and Salmonella. [less ▲]

In Africa, fermented food products are particularly used as weaning foods for young children, pregnant women and the seniors. In Benin, most of these cereals-based foods are manufactured and sold around the streets. These are ablo, dèguè, akpan, abotin, gowé etc ... This study focused on the isolation and enumeration of bacteria and yeast from twenty six (26) samples of traditional African fermented foods. Decimal dilution method allowed us to isolate a total of 42 different strains of microorganisms among which we counted 30 lactic acid bacteria. They confirmed their biological potential by expanding in selective medium MRS. When they were then subjected to screening, the medium of MRS-broth-starch agar, and eight (08) of the isolated strains tested showed their characters of amylolytic strains. The eight strains isolated were tested and finally cultivated at temperatures and pH ranging respectively from 30°C to 60°C and 3.0 to 6.5. These eight (08) amylolytic lactic acid bacteria (ALAB) synthesized enzyme amylase both inside and outside the bacterial cell with a very interesting activity value. The temperature limit between 40 and 45°C is best for the bacteria 26.2, B16 and B18 while the optimum pH for amylase synthesis is between 4.0 and 4.5 for the same microorganisms that have given the largest values of enzyme activity. The best strains 26.2, B16 and B18 secrete more enzymes in extracellular medium than intracellular. [less ▲]

The present article reviews the most important scientific literature on dioxins and PCBs found in poultry liver and their relation with food safety and consumers’ health. Dioxins and polychlorinated biphenyls (PCBs) are persistent organic pollutants with high chemical stability; they are lipophilic compounds and they are not destroyed by microbial, photochemical, chemical or thermal degradation. Dioxins and PCBs are ubiquitous environmental contaminants, which are present in all marine plant and animals, birds, mammals and humans and bioaccumulate through the food chain. In the last years, there has been concern regarding food contamination with different chemical substances and their effect on food safety. More particularly, at the end of the 20th and the beginning of the 21st century, there were a series of incidents related to dioxin and PCBs, which directly affected human or contaminated the soil and accumulated in feed and then in food products, such as poultry liver. It was shown in case of dioxin incident that tetra and penta-chlorinated congeners (the most toxic ones) accumulates selectively in poultry livers. Maximal concentrations have been fixed in the European legislation for dioxins and PCBs in food from animal origin, in order to protect the consumer. Data about background poultry liver contamination are scarce and the few available show levels below the legal limit for dioxins, but data are still lacking for DL-PCBs. [less ▲]

Bisphenol A (BPA) is a chemical compound mainly used for the manufacture of plastic such as polycarbonate. This transparent thermoplastic polymer is used for the fabrication of several food containers like baby bottle, cups, etc. BPA can migrate into food in contact with polycarbonate. There is a worldwide concern about BPA because several studies have shown endocrine disruptor potency of BPA causing possible adverse health effects. In January 2011, the European Commission decided to ban the use of polycarbonate to manufacture baby feeding bottles. In a recent opinion, the Superior Health Council’s issued its concern regarding the currently use of alternatives to polycarbonate in these materials. This work is part of the ALTPOLYCARB project, which aims to study the migration products from non polycarbonate plastic material, and their endocrine disruptor activities. The endocrine disruptor activity(ies) of global migration residues obtained from different kinds of baby bottles will be explored using cell based transactivational assays also named “reporter gene assays”. The MCF7 recombinant cells used here (named MCF7-ER cells) are genetically modified cells containing the firefly luciferase gene, as a reporter gene, and a DNA responsive element specific to the human estrogen receptor. The biological activity of a chemical compound is monitored by the measurement of light emitted by the cells exposed to it (after addition of luciferin, the substrate of luciferase). In a preliminary step, we first screened pure substances, which were shown to migrate from plastic baby bottles, in a recent study performed by Simoneau & al, 2012 . Human estrogen receptor agonistic and antagonistic activities of 25 pure compounds were measured using MCF7-ER cells. After the first screening, some substances clearly show an activity such as BPA, benzophenone, 2-propenoic acid-2-ethylhexyl ester, benzaldehyde-4-methylthio, butylated hydroxytoluene and dodecanoic acid methyl ester, whereas others ask an in-depth analysis to confirm their activity. For active substances only, the study will be continued and a full dose-response curve will be performed in order to assess quantitatively the activity. [less ▲]

This work is part of the ALTPOLYCARB project which aims to study the migration products of alternative to polycarbonate and their endocrine disruptor activities. The first part was to have an overview of the different polymers replacing polycarbonate, that are used on the Belgian market, it resulted in the conclusion that polymers used for the manufacture of baby bottles are mainly polypropylene, polyethersulfone, silicone, polyamide, polystyrene, and melamine. The second part of this work will be to evaluate the endocrine disruptor activity(ies) of global migration residues obtained from different kinds of baby bottles. This (these) activity(ies) will be explored using cell based transactivational assays also named “reporter gene assays.
