Avec l’émergence des nouveaux modes de production alternatifs, pour la plupart associés à la production dite de « qualité différenciée », plusieurs souches de poulets de chair sont éligibles en pratique en Région wallonne. Ces souches se distinguent suivant de nombreux critères dont la durée du cycle nécessaire pour produire une carcasse commercialisable. Or l’âge à l’abattage influencerait fortement les qualités sensorielles de la viande de poulet. Une question essentielle se pose dès lors : quelle influence une modification de l’âge à l’abattage du poulet de chair peut-elle avoir sur la perception de la qualité de la viande par le consommateur ?

Surface fouling is a chronic problem in processing industries. The hygienic state of surfaces is thus a critical parameter with respect to the performance of the production process and to the final quality of the product. For this reason, cleaning and disinfection are essential. The most important first step in implementing a fouling mitigation strategy through cleaning and disinfection is to understand the mechanisms of fouling. This allows ways to be found to reduce, even to eliminate fouling, or to improve the effectiveness of cleaning and disinfection. This paper reviews the relevant literature and summarizes a selection of soil model systems used to aid such improvements. Organic, mineral, microbial, particulate, and composite soil model systems are presented. These soil model systems are of particular relevance in the study of fouling, cleaning or soil adhesion onto solid surfaces in the laboratory environment. The key features of the models, as well as their practical advantages and disadvantages, are described and discussed. [less ▲]

Polysaccharides, proteins, lipids and other biopolymers are the main components of food and pharmaceutical mixtures and may influence interactions at interfaces and thus fouling and cleaning. In this study, quartz particles (10 to 30µm) were used as a model soil for examining the effect of dissolved proteins on the cleanability of substrates after soiling and drying. Glass and stainless steel pretreated by UV-Ozone (StSteel-UVO) were used as model hydrophilic substrates, while hydrophobic substrates were represented by stainless steel cleaned with ethanol (StSteel-Eth) and polystyrene. BSA and β-LGB were used as proteins. The quartz suspensions used for soiling (150g/L) were prepared in pure water and in a solution of each protein (8g/l). After soiling and drying, the cleanability was evaluated using a radial-flow cell, with pure water as the cleaning fluid. When soiling was made with a quartz suspension in pure water, the soil adherence increased with substrate hydrophilicity. This may be explained by better droplet spreading and increase of the capillary forces created upon drying. The presence of proteins in the suspension used for soiling hydrophilic substrates (Glass and StSteel-UVO), decreased the adherence of quartz particles. Its effect was less marked and tended to be opposite for less hydrophilic substrates (StSteel-Eth, Polystyrene). The comparison of different substrates and two proteins showed that the adherence cannot be explained by a simple relation with the contact angle. Other factors may be the solution surface tension itself and the protein behavior at the interfaces created by drying and by rehydratation during cleaning. When considering the influence of substrate on soiling, it must be kept in mind that high surface energy solids (metals, oxides) are readily contaminated in contact with air and lose their hydrophilicity. Amazingly this may improve the substrate behavior regarding cleanability with respect to particulate soil. [less ▲]

Cheese processing is one of the possibilities of farm diversification. From 30 cow milks were made 60 cheeses on which several parameters were measured and on which NIR spectra were obtained. Our results show that cheese spectra could be discriminated between different ripening times of cheeses and the access to pasture or not for the animals which had produced the milk from which the cheese was made. Moreover, highly significant correlations were obtained for the color and the texture of cheeses between the values measured in the laboratory and the NIR spectra. [less ▲]

Safflower (Carthamus tinctorius) is an oilseed crop, which, for many years, has been grown on a relatively small scale in parts of North Africa and Middle East (Purdy and al., 1959).

Traditional olive oil production is limited by its high cost, mainly due to labour expenses for harvesting and pruning. New olive cultivars (e.g. Arbequina, Arbosana, Koroneiki) with greater adaptability to modern irrigated high-density orchards and producing good quality olive oils are highly demanded by an olive oil industry in continuous change The aim of this study is the characterization of monovarietal virgin olive oils from three cultivars (Arbequina, Arbosana and Koroneiki) recently introduced in east of Morocco, and the comparison with traditional local Picholine Marocaine olive oil. Several analytical parameters were evaluated; including quality index, Triacylglycerol, fatty acids, phenolic and chlorophyll contents and oxidative stability. Significant differences between the analysed olive oils were detected. Olive oils from Koroneiki and Arbosana cultivars had higher values of oleic acid (respectively 76.24 and 75.68 %); Picholine olive oil, had the lowest one 67.49%. Koroneiki olive oil was noteworthy for its higher content of phenolic compounds (459.48 mg/ kg) and a high oxidative stability (93.16 h). We concluded that the recently introduced cultivars are well adapted to the eastern area of Morocco and could be of great interest for producing monovarietal olive oils. [less ▲]

In this study, four safflower varieties, originating from Spain (Rancho), India (Sharda) and Morocco (Cartamar and Cartafri) cultivated at the experimental station of OUJDA (semi-arid region of Eastern Morocco) were evaluated for their oil yield and seed oil quality. The analysis of results revealed significant differences among varieties for all traits. Indeed, our result show that seeds of the four varieties have important oil content ranged between 35.38% (Rancho) and 28.84% (Cartamar). Characterization of these oils showed a low value of acidity index less than 0.7% for all the varieties but significant differences in their peroxide values ranged between 4.5 meq O2/Kg (Cartamar) and 31.21 mEqO2/Kg (Rancho) and high value of phenolic content between 143 ppm (Rancho) and 97 ppm (Sharda). Analysis of the fatty acids shows that linoleic acid is the main fatty acid ranged between 77.94% (Cartamar) and 79.98% (Sharda). Oils of those four varieties can be classified in the linoleic acid group. The analysis of triglycerides by HPLC shows 10 molecular species of TAG (LLL, LPL, LLO, PLO, LLS, POP, OOO, POO, SOO, PPL). The trilinoleate (LLL) is the main molecular species with more than 50%. Safflower seed oil cultivated in eastern Morocco presents good physicochemical proprieties (polyphenols and Omega 6 richness); therefore, safflower culture could be suggested for all areas of Morocco, including the areas of low pluviometry, while the potential for culture of other oilseeds is more limited.
