Paperback. Condizione: new. Paperback. This paper presents the results of a study conducted on the extraction of oil from Kashobwe fry using an organic solvent through maceration in an ethanol and ether medium, which allows for the extraction of both neutral lipids and complex lipids. The specific objective is to evaluate the capacity and determine the efficiency of the solvents (petroleum ether and ethanol) in extracting oil from Kashobwe fry. Among the methods for oil extraction are those that use organic solvents and those that use cooking and pressing. The methodology included a literature review providing an overview of fish oil and its extraction; the method used was hot maceration; the process began with sampling, grinding, weighing on an analytical balance, and allowing the sample to macerate in the solvent for several hours at varying temperatures; several parameters, such as temperature, time, and solid-to-liquid ratio, were varied.

This item is printed on demand - it takes 3-4 days longer - Neuware -Le présent travail dévoile résultats d'une étude menée sur l'extraction de l'huile des fretins Kashobwe dans un solvant organique par macération en milieu éthanoïque et éthérique permettant à la fois d'extraire les lipides neutres et les lipides complexes. L'objectif spécifique est d'évaluer la capacité et déterminer l'efficacité des solvants (éther de pétrole et éthanol) dans l'extraction de l'huile de Fretins Kashobwe. Parmis les méthodes pour l'extraction des huiles sont d'abord celles qui emploie des solvants organiques et celles qui utilisent la cuisson-pressage. La méthodologie a englobé outre une revue bibliographique présentant une vue générale sur l'huile de poissons et sur son extraction, la méthode utilisée est la macération à chaud; tout d'abord passer par l'échantillonnage, broyage, peser sur la balance analytique, et le laisser macérer dans le solvant pendant plusieurs heures et à une température variante; il y a eu variation des quelques paramètres comme la température, le temps et le rapport solide-lique. 76 pp. Französisch.…

Paperback. Condizione: new. Paperback. Il presente lavoro illustra i risultati di uno studio condotto sull'estrazione dell'olio dagli avannotti di Kashobwe in un solvente organico mediante macerazione in ambiente etanico ed etereo, che consente di estrarre sia i lipidi neutri che quelli complessi. L'obiettivo specifico e valutare la capacita e determinare l'efficacia dei solventi (etere di petrolio ed etanolo) nell'estrazione dell'olio dagli avannotti di Kashobwe. Tra i metodi di estrazione degli oli vi sono innanzitutto quelli che impiegano solventi organici e quelli che utilizzano la cottura e la spremitura. La metodologia ha compreso, oltre a una rassegna bibliografica che offre una panoramica generale sull'olio di pesce e sulla sua estrazione, il metodo utilizzato, ovvero la macerazione a caldo; in primo luogo si procede al campionamento, alla macinazione, alla pesatura sulla bilancia analitica e alla macerazione nel solvente per diverse ore a temperature variabili; sono stati variati alcuni parametri quali la temperatura, il tempo e il rapporto solido-liquido.

Die vorliegende Arbeit praesentiert die Ergebnisse einer Studie zur OElgewinnung aus Kashobwe-Jungfischen in einem organischen Loesungsmittel durch Mazeration in Ethanol und Ether, wodurch sowohl neutrale als auch komplexe Lipide extrahiert werden koennen. Das konkrete Ziel besteht darin, die Kapazitaet zu bewerten und die Wirksamkeit der Loesungsmittel (Petroleumether und Ethanol) bei der OElgewinnung aus Kashobwe-Jungfischen zu bestimmen. Zu den Methoden zur OElgewinnung zaehlen vor allem solche, bei denen organische Loesungsmittel zum Einsatz kommen, sowie solche, bei denen das Kochen und Pressen angewendet wird. Die Methodik umfasste neben einer Literaturrecherche, die einen UEberblick ueber Fischoel und dessen Gewinnung bot, die Methode der Heissmazeration; zunaechst erfolgten Probenahme, Zerkleinerung und Wiegen auf der Analysenwaage, anschliessend wurde die Probe mehrere Stunden lang bei unterschiedlichen Temperaturen im Loesungsmittel mazeriert; dabei wurden verschiedene Parameter wie Temperatur, Zeit und Feststoff-Fluessigkeits-Verhaeltnis variiert.
