that is currently discarded but could be considered as a potential source of valuable natural products due to its content in phenolic compounds and other natural antioxidants. The aim of this work was to valorize this by-product by ruminants. Thus, the proposed strategy was to distribute olive mill wastewater (OMWW) to dairy cows in production. This large-scale recovery required two prior steps: i) explore the variability in OMWW composition from Algerian olive oil mills considering extraction processes (traditional discontinuous press vs 3-phases centrifugal system)
and olive varieties (Azerradj, Sigoise, Chemlal) and, ii) estimate its in vitro degradability in presence of ruminale microbiota in batch systems. Whereas pH, dry or organic matter content didn't vary, there was a significant difference in ash content according to extraction process and olive variety. Carotenoid content was 2.2-fold higher with 3-phases than with press systems whereas tocopherol content was not significantly different. Among the phenolic compounds quantified, tyrosol was usually the most abundant whereas oleuropein concentrations were highly variable. Differences in phenolic compound concentrations were more pronounced between olive varieties than between processes.
The anaerobic biodegradation of OMWW reveals their extensive use by the rumen microbiota. Compared to vetch hay oats, they produce a small amount of gas. In addition, in vitro fermentation generates a low volume of methane. This allows OMWW to improve the efficiency of ruminal microbial flora in the biomass production and inhibition of methane production, a major source of energy loss for the animal. This result allows us to recommend their use as a food additive in the diet of ruminants
The distribution of OMWW in the diet of dairy cows has allowed us to define the
conditions for presentation of OMWW to dairy cows (shape, adaptation, and intake level) and their acceptability. Our results showed that the level of quantitative output (milk production) and fine composition of milk (vitamin A, E and phenolic compounds) did not seem to be affected significantly. The lack of significant differences between groups of animals is due to the fact that the OMWW distributed to the cows were not particularly rich in micro-components compared to forage.

Nutrition, Alimentation et Technologies Agro-AlimentairesTags : Medeghissa fromage traditionnel enquête diagramme de fabrication fondu traditional cheese survey manufacturing diagram melted مدغيسة جبن تقليدي تحقيق ميداني مخطط الصناعة جبن ذائب Index. décimale : 640 Industrie Alimentaire Résumé : Medeghissa is a traditional Algerian cheese known among the Chaouia under its
original name Imedeghest. It is a melted cheese, prepared by cooking semi dry Klila in whole
milk from cow, goat or sheep, on low heat. The aim of our work is the characterization
Medeghissa basing on two integrated and dependent axes, namely a characterization by
means of a field survey carried out in the Wilaya of Oum El-Bouaghi and Affected 105
women of rural origin; And an experimental characterization of the collected samples from
farms and controlled manufactures (physicochemical, microbiological and sensorial
analyzes).
The cheese-making diagram was based on survey results and verified on the laboratory
scale. 84 women questioned know this cheese but its manufacture was limited on 3.8% of
them. Madghessa is eaten as a snack and appreciated for its elasticity and taste by all women
surveyed.
The manufactured Madghessa has a pH average of 4.82 ± 0.15 and an acidity of
0,41±0,15 g / 100 g. The recorded dry extract is 34.78 ± 1.2 g / 100 g. This result is similar to
that of the collected samples (33.64 ± 4.13 g / 100 g). This cheese has an average fat content
of 7.78 ± 1.99 g / 100 g and a protein level of 25.94 ± 4.53 g / 100 g. According to codex
alimentarius STAN A-6 (1978), this cheese can be classified under lean, soft cheese (MG / ES
<10%), HRED> 67%).
According to the microbiological analyzes on the different samples, the cheese has a
good hygienic quality marked by a total absence of the contamination indicator germs and
pathogenic germs namely: total and fecal coliforms, faecal streptococci, Salmonella and
Staphylococus aureus As well as spores of sulfito-reducing anaerobes. Madghessa has a low
microbial load in the range of 102 to 103 CFU / g for the total mesophilic flora. The
mesophilic and thermophilic lactic bacteria reach values of the order 104 CFU / g. On the
other hand, the number of yeasts and molds shows variability from zero to 103 CFU / g.
On the organoleptic level, Madghessa is a soft cheese, with a weak acid taste. The paste
of the cheese is elastic with pseudoplastic character when it is hot and becomes firm with the
cooling. Its smell and aroma are mainly of the lactic family.

The well-known health benefits of olive oil are linked to its fatty acid composition in which oleic acid is the main component, and the presence of minor biomolecules, such as vitamins and natural antioxidants.
The strong demand for quality virgin olive oil is not only due to its health virtues, but also to its organoleptic properties.
In Algeria, plantations are characterized by great diversity and for the most part, by a traditional olive orchard. The consumption of oil maâsras is today a basic diet in many rural areas of the country. In these regions, oils are considered to be of good quality. The present study on olive oil produced in several olive growing regions of Algeria has the dual purpose of studying the chemical parameters and fatty acid composition by conventional analytical methods, and of characterizing these oils by spectral methods, including 3D- fluorescence spectroscopy.
Different chemometric methods: Principal Component Analysis (PCA), Canonical Discriminant Analysis (CDA), Independent Component Analysis (ICA), and PARAFAC (PARAllel FACtor analysis) are used to treat the data.
The first results indicate that the chemical composition of olive oils from different regions of Algeria is quite variable.
The Principal Component Analysis (PCA) was used for an initial exploratory analysis of the data. The first three latent variables explain 64.1% of the total variance of the samples from the five regions. Then, a Canonical Discriminant Analysis (CDA) showed that the most discriminant variables are K270 and Delta K for oil samples from the region of Constantine, the peroxide and γ-tocopherol for samples from the regions of Tizi Ouzou and Sétif, respectively.
The variations due to the presence of Rayleigh and Raman scattering in excitation– emission fluorescence matrices, distort the PARAFAC model.
A solution to eliminate the artefacts interfering with the relevant information was achieved by applying Independent Component Analysis to the row-wise unfolded array. A PARAFAC model was then built on the refolded array, reconstructed without the independent component(s) related to the “artefact signals”. The PARAFAC components obtained were interpreted by relating them to some compounds present in the analysed samples. The results of multivariate analyses show that the chemical parameters of olive oils contain enough information to distinguish the production areas of studied Algerian oil.Note de contenu : Annexes.
