The present study intends to contribute to the mechanization of cashew apple juice filtration process in Benin. Its aim is to evaluate the technical performances of a filter-press in order to improve cashew apple juice quality. Four treatments were tested, combining two types of juices (raw and clarified) with two types of filtration media (nylon and cotton) available on the market. Therefore, the raw flow of filtration, the residual humidity rate of filtration cakes, the filtrate yield, the filtrate particles content, the particles reduction report, the particles reduction rate, the percentage of extracted cake, and the hourly capacity of the filter-press were assessed. Physico-chemical, microbiological and sensory characteristics of juices produced from the various treatments were determined. The filtration of the clarified juice with cotton cloth showed the best performances concerning the average filtrate yield obtained which was 56.77% with particles content of 1.046 g/l in the clarified and filtered juice and 212.157 kg/hour capacity of the equipment. The juice produced through that treatment had on average a Brix value of 11, a pH of 3.954 and a titratable acidity of 0.58%. Its vitamin C content was 73.225 mg/100g for a tannins content of 2.05 mg/100ml and respective average values in magnesium and potassium of 90.8 and 1174.9 mg/l, respectively. The absence of the mesophilic bacteria, yeasts and moulds showed that raw and clarified filtered juices are healthy. The clarified juice filtered with cotton cloth obtained the best scores for its clarity and color accepted. The study concludes that the filtration of cashew apple clarified juice with the filter-press and cotton cloth, is the best treatment according to the equipment capacity, the average yield performance obtained and the lowest particles content of the juice produced. This process must be perfected and transferred to cashew apple juice producers in Benin to improve the quality of the product. [ABSTRACT FROM AUTHOR]

This study aims to evaluate and compare the technical performance of major equipment and procedures for smoking shrimp in southern Benin. The important shrimp fisheries in southern Benin were surveyed to identify and characterize the smoking shrimp used. The results indicated that four (04) main oven were used including the Barrel oven, the Chorkor oven, the traditional clay oven and the oven parallelepiped. While Barrel oven is the most used (95%), the Chorkor oven is generally the most efficient: it is characterized by a greater production capacity (54.07 kilograms of fresh shrimp), an average fuel consumption (0.63 kg / kg of fresh shrimp) and a lower water content of smoked shrimp (15.41%). Moreover, it is easy to use and secure the best health of the operators against the risk of burns and choking smoke nuisance. Microbiological analyzes revealed that although the quality of fresh shrimp was failing because of unsafe areas and fishing equipment as well as bad practices capture and handling, smoking improves overall quality and makes it consistent normative requirements> [ABSTRACT FROM AUTHOR]

L'Agence Nationale pour la Transfusion Sanguine ANTS du Bénin, dans sa démarche qualité, organise chaque année des Evaluations Interne de la Qualité EIQ pilotées par la Cellule Assurance Qualité et Hémovigilance en collaboration avec la Direction de la Production et Direction de la Prospective et la Recherche. En 2018, l'EIQ s'est étendue au test de compatibilité au laboratoire. L'objectif est de renforcer la sécurité transfusionnelle. C'est une étude prospective transversale effectuée dans 49 structures a pris en compte 192 échantillons. Elle s'est déroulée du 03/10 au 30/12 2018 en quatre phases : phase préparatoire ou phase d'échantillonnage, phase d'acheminement des échantillons dans les structures ciblées pour la réalisation des tests de l'EIQ et la transmission des résultats à l'ANTS en 10 jours, phase de dépouillement et d'analyse des résultats collectés, phase de rédaction du rapport et de feed-back aux structures. Les résultats sont sous forme de non-conformités par rapport aux résultats de référence : Sérologie VIH 4 % ; HBs 0,8 % ; HCV 4,31 % ; syphilis 3,12 %. Immunohématologie : groupage sanguin (double population 59 %) ; test de compatibilité négatif en milieu de Coombs 6 % ; test de compatibilité positif en milieu de Coombs 21 % ; Validité des réactifs utilisés : VHB et Syphilis 3 % ; Immunohématologie 4 % Enregistrement des réactifs : VIH 4 % ; VHB 16 % ; VHC 33 % ; syphilis 22 %. La comparaison des résultats de 2017 et 2018 a montré une diminution des non-conformités en 2018.L'EIQ est importante pour le renforcement de la sécurité transfusionnelle. En 2018, elle a révélé de non-conformités qui suscitent des mesures correctives. [ABSTRACT FROM AUTHOR]
