Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This work initially explores both solvent and cold press extracting techniques of the pumpkin (Cucurbita maxima) seeds of a Tunisian variety named Béjaoui. It additionally compares the chemical composition of the seed oil of the Béj…aoui variety with that of a commercial Cucurbita pepo subsp. Pepo var. Styriaca originating from Austria. Both examined pumpkin species and their extraction techniques had significant effects on antioxidant activity, Saturated Fatty Acid (SFA), Polyunsaturated Fatty acid (PUFA), Gamma-tocopherol, and pigment contents. The cold press techniques were found to improve the Gamma-tocopherol content and the oxidative stability when compared to solvent extraction (599.33 mg/kg and 3.84h for the Komet DD 85 G press model against 435.75 mg/kg and 3.88h for the MUV2 65 model). The higher polarity of chloroform/methanol promoted the extraction of polyphenols (54.41 mg GAE/kg). Furthermore, the higher antioxidant activity of pumpkin seed oil extracted by the MUV2 65 press (0.31 mM Trolox/kg) might be attributed to the fat-soluble antioxidants such as Gamma-tocopherols, chlorophylls (179.6 mg/kg), carotenoids (66 mg/kg), and total polyphenol content (36.07 mg GAE/kg). 52 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Este trabajo explora inicialmente las técnicas de extracción con disolventes y en frío de las semillas de calabaza (Cucurbita maxima) de una variedad tunecina denominada Béjaoui.

Las dos especies de calabaza examinadas y sus técnicas de extracción tuvieron efectos significativos sobre la actividad antioxidante, el contenido en ácidos grasos saturados (AGS), ácidos grasos poliinsaturados (AGPI), ¿-tocoferol y pigmentos.

Taschenbuch. Condition: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Este trabalho explora inicialmente tanto as técnicas de extracção da abóbora (Cucurbita maxima) com solvente como as técnicas de extracção a frio das sementes de uma variedade tunisina chamada Béjaoui. Além disso, compara a composição q…uímica do óleo de semente da variedade Béjaoui com a de uma Cucurbita pepo subsp. comercial Pepo var. Styriaca, originária da Áustria. Ambas as espécies de abóbora examinadas e as suas técnicas de extracção tiveram efeitos significativos na actividade antioxidante, Ácido Gordo Saturado (SFA), Ácido Gordo Polinsaturado (PUFA), ¿-tocoferol, e no conteúdo de pigmentos. Verificou-se que as técnicas de prensa a frio melhoravam o conteúdo de ¿-tocoferol e a estabilidade oxidativa quando comparado com a extracção com solventes (599,33 mg/kg e 3,84h para o modelo Komet DD 85 G press contra 435,75 mg/kg e 3,88h para o modelo MUV2 65). A maior polaridade do clorofórmio/metanol promoveu a extracção de polifenóis (54,41 mg GAE/kg). Além disso, a maior actividade antioxidante do óleo de sementes de abóbora extraído pela prensa MUV2 65 (0,31 mM Trolox/kg) pode ser atribuída aos antioxidantes lipossolúveis tais como ¿-tocoferóis, clorofilas (179,6 mg/kg), carotenóides (66 mg/kg), e ao teor total de polifenóis (36,07 mg GAE/kg).VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 52 pp. Portugiesisch.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Questo lavoro esplora inizialmente le tecniche di estrazione con solvente e a freddo dei semi di zucca (Cucurbita maxima) di una varietà tunisina chiamata Béjaoui. Inoltre, confronta la composizione chimica dell'olio di semi della variet…à Béjaoui con quella di una Cucurbita pepo subsp. Pepo var. Styriaca proveniente dall'Austria. Entrambe le specie di zucca esaminate e le relative tecniche di estrazione hanno avuto effetti significativi sull'attività antiossidante, sui contenuti di acidi grassi saturi (SFA), acidi grassi polinsaturi (PUFA), ¿-tocoferolo e pigmenti. Le tecniche di pressatura a freddo sono risultate in grado di migliorare il contenuto di ¿-tocoferolo e la stabilità ossidativa rispetto all'estrazione con solvente (599,33 mg/kg e 3,84h per il modello di pressatura Komet DD 85 G contro 435,75 mg/kg e 3,88h per il modello MUV2 65). La maggiore polarità di cloroformio/metanolo ha favorito l'estrazione dei polifenoli (54,41 mg GAE/kg). Inoltre, la maggiore attività antiossidante dell'olio di semi di zucca estratto con la pressa MUV2 65 (0,31 mM Trolox/kg) potrebbe essere attribuita agli antiossidanti liposolubili come i ¿-tocoferoli, le clorofille (179,6 mg/kg), i carotenoidi (66 mg/kg) e il contenuto totale di polifenoli (36,07 mg GAE/kg).
