Detailed study of Brazil nut (Bertholletia excelsa) oil micro-compounds : Phospholipids, tocopherols and sterols

The oil of the Brazil nut (Bertholletia excelsa) was studied for its composition in fatty acids, tocopherols, sterols and phospholipids. The fatty acids composition of phospholipids was also studied. These results were compared to those of sunflower, walnut, almond, soya and olive oils. Its high content of unsaturated fatty acids, of [bêta]-tocopherol and of [bêta]-sitosterol gave to the Brazil nut interesting antioxidant and anti-cholesterol properties. The composition of fatty acids in phospholipid is very different from the composition of the oil. Linolenic acid, which is not present in the oil, is present at a high level in phosphatidylethanolamine. (Résumé d'auteur

L’ apport du Marketing Territorial dans l’amélioration de l’Image de Marque de la Destination Touristique, cas de la pandémie Covid 19.

Les crises naturelles et humaines sont devenues ces dernières années plus récurrentes, notamment les pandémies comme celle de la covid 19.L’impact sur le secteur touristique en général et les destinations en particulier est énorme.La réflexion sur l’amélioration de l’image de marque des territoires touristiques et les solutions possibles pour faire revenir les touristes sur les sites touristiques sont d’actualité.  Ces circonstances que nous vivons actuellement imposent aux parties prenantes du secteur touristique et les gestionnaires de l’image de marque des destinations d’acquérir de nouvelles pratiques permettant la gestion des crises sanitaires. La revue de littérature et les apports du marketing territorial que nous proposant dans ce papier explique le phénomène observé et propose de nouvelles implications en matière de gestion de l’image de marque capable de motiver à nouveau les touristes pourrevivre une nouvelle expérience touristique. C’est dans cette perspective que l’usage des approches et des outils du marketing territorial pourraient atténuer l’impact des épidémies, permettraient la relance du marché touristique et assurer un retour en force du secteur de tourisme

Malting Quality of ICARDA Elite Winter Barley (Hordeum vulgare L.) Germplasm Grown in Moroccan Middle Atlas

The use of barley (Hordeum vulgare L.) in Morocco is still limited to food and feed despite the amplified demand by local industries for imported malt. This study aims to evaluate 36 barley elite lines for major grain physicochemical parameters and malt quality traits. Analysis of variance, Pearson correlation, principal component analysis (PCA), and hierarchical cluster analysis (HCA) were performed. The results showed significant genotypic variation among genotypes for individual grain and malt traits. High broad sense heritability was obtained for all traits except for plump grain percentage, malt friability, and germination capacity. Starch, malt extract, Kolbach index, grain area, and test weight correlated significantly and negatively with barley protein. Malt extract correlated positively with Kolbach index and starch, but a negative correlation with soluble protein and malt protein was found. Based on 12 characters, 77% of the total genotypic variation was explained by the three first principal components following PCA and four clusters were depicted based on HCA. Genotypes of high interest with desirable levels of quality standards were identified to be used as a malt quality traits donor while designing crossing programs

Formulation and stabilization of oil-in-water nanoemulsions using a saponins-rich extract from argan oil press-cake

In this study, we formulated and stabilized oil-in-water nanoemulsions using a crude extract from argan press-cake as sole emulsifier. Various extracts from argan press-cake were prepared in order to select the most surface-active one(s) foreseeing emulsions preparation. Fifty percent (v/v) ethanolic extract reduced the interfacial tension to a minimum value at both MCT oil and soybean oil interfaces (12.7 and 10.5 mN m−1 respectively). This extract was also effective at producing fine emulsions with small droplet sizes (d3,2 < 115 nm) and good physical stability using different oils such as soybean oil, MCT oil and fish oil and at conventional homogenization conditions (100 MPa for 4 passes). On the other hand, the emulsions were very sensitive to NaCl addition (≥25 mM) and to acidic pH (<3) indicating that the main stabilization mechanism is electrostatic, likely due to the presence of surface-active compounds with ionizable groups such as saponins
