Consommation de viande de porc en Chine : revirement de tendances

Consulter le resumé

Valérie Diot, Baromètre Porc (FRA), 2019, n° 501, octobre, synthèse du mois, p. 8

Le porc est au coeur des habitudes alimentaires en Chine. Sous l’influence des évolutions socio-économiques, la hausse du niveau de vie et l’urbanisation, les consommateurs privilégiaient, jusqu’à il y a peu, une offre plus élaborée et de meilleure qualité. Face à la crise de la FPA, tel un retour aux fondamentaux, la question de la satisfaction de la demande en viande porcine, se pose à la Chine.

Biopréservation et hautes pressions : des outils pour la maîtrise des dangers microbiologiques dans les aliments

Consulter le resumé

Hélène Simonin ( Univ. Bourgogne Franche-Comté, AgroSup Dijon) et al., IAA, revue des industries agro-alimentaires (FRA), 2019, mai-juin, 6 pages

L’utilisation d’additifs conservateurs est souvent nécessaire pour assurer la sécurité microbiologique des produits carnés réfrigérés faiblement acides. Le projet ANR BLac HP (2014-2019) a étudié une nouvelle stratégie de stabilisation des produits carnés réfrigérés pour assurer le contrôle des flores indésirables à la fois végétatives et sporulées. Grâce à une approche pluridisciplinaire, les travaux ont montré que la combinaison de la biopréservation par des bactéries lactiques et d’un traitement hautes pressions permettait d’assurer la qualité microbiologique de dés de jambon cuits à teneur réduite en nitrite pendant toute leur durée de vie. Le traitement permet de plus une qualité sensorielle optimale sans impact environnemental supplémentaire par rapport au procédé conventionnel.

Development of a quantative PCR method coupled with PMA to quantify viable Salmonella spp. cells in the pork supply chain

Consulter le resumé

Sabine Jeuge et al., 13e SafePork, 26-29 août 2019, Berlin, Allemagne

In 2017, Salmonella spp. was implied in 30% of foodborne diseases in France (SPF, 2019). Few data on the contamination levels of Salmonella spp., are available along the pork supply chain. The protocol of the standard method (ISO/TS 6579-2:2012) is time-consuming and culture-based methods using chromogenic media are less efficient for matrices with high levels of back ground flora, and for recovering stressed cells. Along the food chain, the cells may be impacted by various stresses (e.g. chemical or thermal), which may lead to physiological changes and the emergence of viable but non-culturable cells (VBNCs).

Salmonellosis is a major cause of foodborne outbreaks caused by bacteria in Europe. In 2014, the European Commission reinforced the survey of this contaminant in the pig and pork industry by the competent authority. In this context, French General Directorate for Food required a new system to centralize regulatory own-checks results for Salmonella in pig carcasses.

Predicting the Quality of Meat: Myth or Reality?

Consulter le resumé

Cécile Berri (Inrae) et al., Foods, 2019, volume 8, n° 10, 22 pages

This review is aimed at providing an overview of recent advances made in the field of meat quality prediction, particularly in Europe. The different methods used in research labs or by the production sectors for the development of equations and tools based on different types of biological (genomic or phenotypic) or physical (spectroscopy) markers are discussed. Through the various examples, it appears that although biological markers have been identified, quality parameters go through a complex determinism process. This makes the development of generic molecular tests even more difficult. However, in recent years, progress in the development of predictive tools has benefited from technological breakthroughs in genomics, proteomics, and metabolomics. Concerning spectroscopy, the most significant progress was achieved using near-infrared spectroscopy (NIRS) to predict the composition and nutritional value of meats. However, predicting the functional properties of meats using this method—mainly, the sensorial quality—is more difficult. Finally, the example of the MSA (Meat Standards Australia) phenotypic model, which predicts the eating quality of beef based on a combination of upstream and downstream data, is described. Its benefit for the beef industry has been extensively demonstrated in Australia, and its generic performance has already been proven in several countries.

Arnaud Bridier (Anses) et al., Scientific Reports, 2019, volume 9, n° 1, 10 septembre, 13 pages

To guarantee food safety, a better deciphering of ecology and adaptation strategies of bacterial pathogens such as Salmonella in food environments is crucial. The role of food processing conditions such as cleaning and disinfection procedures on antimicrobial resistance emergence should especially be investigated. In this work, the prevalence and antimicrobial resistance of Salmonella and the microbial ecology of associated surfaces communities were investigated in a pig slaughterhouse before and after cleaning and disinfection procedures. Salmonella were detected in 67% of samples and isolates characterization revealed the presence of 15 PFGE-patterns belonging to five serotypes: S.4,5,12:i:-, Rissen, Typhimurium, Infantis and Derby. Resistance to ampicillin, sulfamethoxazole, tetracycline and/or chloramphenicol was detected depending on serotypes. 16S rRNA-based bacterial diversity analyses showed that Salmonella surface associated communities were highly dominated by the Moraxellaceae family with a clear site-specific composition suggesting a persistent colonization of the pig slaughterhouse. Cleaning and disinfection procedures did not lead to a modification of Salmonella susceptibility to antimicrobials in this short-term study but they tended to significantly reduce bacterial diversity and favored some genera such as Rothia and Psychrobacter. Such data participate to the construction of a comprehensive view of Salmonella ecology and antimicrobial resistance emergence in food environments in relation with cleaning and disinfection procedures.

Drivers of (dis)liking: Systematic pairwise preference tests to reveal the relationship between boar taint and consumer acceptance

Consulter le resumé

Daniel Mörlain (University of Göttingen, Department of Animal Science) et al., 65th International Congress of Meat Science and Technology (ICOMST), 4-9 août 2019, Potsdam/Berlin, Allemagne, poster, p. 66-68

To improve animal welfare, in 2010 a European Declaration proposed a total ban on castration. Entire male pigs, however, can develop an off-odour, called boar taint. To prevent consumers complaints, a quantitative relationship of boar taint compounds (or intensity) with consumer dissatisfaction needs to be established. Pairwise preference tests (Prescott et al, 2005) were deemed a more straightforward approach than sequential monadic testing to establish rejection thresholds.

Attitudes of Eastern European consumers towards surgical castration and immunocastration of piglets

Consulter le resumé

Igor Tomasevic (University of Belgrade, Faculty of Agriculture, Belgrade, Serbia) et al., 65th International Congress of Meat Science and Technology (ICOMST), 4-9 août 2019, Potsdam/Berlin, Allemagne, p. 12-13, poster

Castration of male piglets is a common practice in pig husbandry performed to avoid boar taint, an offensive odour connected mainly with the presence of skatole and androstenone (Claus, Weiler, & Herzog, 1994) that can be perceived during the cooking and/or heating of pork from uncastrated male pigs. Taking into account relatively high animal welfare standards and discrepancy in public interest in farm animal welfare and ethical issues across European countries, generalisation of findings from Western European consumer studies to Eastern European countries would be quite questionable.

Evenmore so because a general insight into Eastern European meat consumers’ perceptions and behaviour is largely unavailable (Font-i-Furnols & Guerrero, 2014), except for a few studies published recently (Tomasevic et al., 2018). The aim of this research was to investigate the attitudes of Eastern European consumers regarding surgical and immuno-castration.

A new EU regulation on carcass classification applies from July 2018. The new reference to calibrate the pig classifi cation methods is a lean meat percentage based on total dissection of a half-carcass (LMPtd). Manual dissection can be replaced by an unbiased computed tomography (CT) procedure. 
Daumas and Monziols (2018) calibrated a simple, accurate and robust CT method in order to make it useful internationally and at least in Europe. A trial for approval of grading methods in Lithuania gave the opportunity to validate this CT procedure

The objective of the study was to develop models and assess the estimation error of bellies composition using a magnetic induction device.
Magnetic induction, which principle takes advantage of the dielectric properties of tissues, was successfully tested by Swan et al. (2001) on bellies, hams and shoulders. Simoncini et al. (2012) estimated fat and muscle composition of hams with a more recent device.
In the following, we draw conclusions based on experimental data on the extent to which such a device can be used to grade bellies.

Influencing wavelength comparison in pls models for the prediction of pork meat quality by vis-nirs

Consulter le resumé

Antoine Vautier, 65th International Congress of Meat Science and Technology (ICOMST), 4-9 août 2019, Potsdam/Berlin, Allemagne, poster

For the needs of a running project dealing with hyperspectral imaging, we wanted to define the spectral range specifications of the device being built. The reference data we expect to predict on pork meat cover a wide diversity of parameters: pH, drip loss, cooking yield and intramuscular fat. In previous studies focusing on VIS-NIRS (Visible and Near Infra Red Spectroscopy) prediction of the meat quality, we mainly used the 350-1800 nm spectral range of a Labspec4 spectrometer (ASDI). Because this spectral range seems to be too wide for a single ready-to-use hyperspectral camera, we decided to take another look on our previous NIRS studies and investigate which wavelength are the most predictive. The objective was to make a comparison of the influencing wavelength that are included in the PLS prediction equations, for each of the meat quality parameters we had studied.

Addition of vitamin E in pigs feed: could prevent cured-meat promotion of colon carcinogenesis in rats

Consulter le resumé

Aurélie Promeyrat et al., 65th International Congress of Meat Science and Technology (ICOMST), 4-9 août 2019, Potsdam/Berlin, Allemagne, poster

Based on epidemiological studies, excessive consumption of cured meats induces a slight, but significant, increase in the risk of developing colorectal cancer [1]. Among the various hypotheses, recent studies have proposed the central role of heme iron in this positive association. Heme iron catalyzes the formation of genotoxic and cytotoxic nitroso-compound (NOCs) and lipid peroxidation end products (alkenals). Based on the important role of peroxidation and nitrosylation in the effect on cancer risk, our recent studies has made possible to propose a limitation of this effect via the enrichment of cured meat products with vitamin E during their manufacture [2]. In addition, supplementation in pig diet would also appear interesting to protect cured meat from the formation of carcinogenic substances, NOCs and alkenals [3]. In the present study we assess for the first time the effect of adding vitamin E in pig feed on preventing the promotion of colorectal carcinogenesis in rats fed a sausage-based diet from supplemented animals compare to sausage-based diet from control animals .

Salt intake from processed meat products: benefits, risks and evolving practices

Consulter le resumé

Gaëlle Petit et al., Comprehensive reviewsin food science and food safety, 2019, volum 18, 25 juillet, p. 1453-1473

Currently, there is major consumer concern about dietary salt intake worldwide. However, even with the development of contemporary preservation practices, sodium chloride is still essential in processed meat products. Despite a long history of use, salt is now seriously controversial in food due to health concerns that are mostly related to high blood pressure and cardiovascular risks. Changes in meat processing methods have reduced those potential risks, but different perceptions continue to shape how consumers and society view dietary salt. The current consumer demand for additive-free food, such as the clean-label movement, has renewed consumer willingness for naturalness in food products.
