Index. décimale : 640 Industrie Alimentaire Résumé : The intense production of eggs in Algeria, leads to an overabundant and availability of spent hens. Hens’ meat is perceived and judged to be very tough and undesirable for direct consumption; henceit is entirely oriented tothe transformation. The main objective of this preliminary study was to study the effect of slaughter age on the carcass traits and meat quality of ISA (F15) spent hens, the largest produced poultry in Algeria. To reach those objectives, total of 16 spent hens at different ages (220 vs 337 days, 8 animals per batch) were used. Toughness and texture/acceptability attributes (tenderness, juiciness, cohesiveness, chewiness, residues and overall liking) of breast muscle have been assessed by penetrometry and sensory analysis using a trained panel, respectively. Water holding capacity, percentage of released water, cooking losses, ultimate pH andmyofibril fragmentation index (MFI) were also determined.A proteomiccharacterization of sarcoplasmic and myofibrillar proteins was done on eachanimal of the two hensgroup. The preliminary results of this study showed that the penetration depth was negatively correlated with tenderness scoresand myofibril fragmentation index. Tenderness scores were negatively correlated with animal age and positively with ultimate pH. The meat of the studied hens has been judged very acceptable according to the highest scores (scores > 5.5/10) given by the panelists. Consequently, it appears that the overall liking scores are independent of hens’age. Otherwise, monodimensionalSDS-PAGE analysis displayed some differences in the proteomicprofiles of the two groupsin spite ofthe usefulness of the bi-dimensional electrophoresis (2-DE) in this study
to determine the underlying mechanisms oftoughness/tenderness. Through this preliminary study, it seems thatISA F15 spent hens can be used for a domestic consumption.

Titre : Utilisation de l’huile essentielle de Citrus limon comme agent conservateur et aromatique dans la crème fraîche Type de document : texte imprimé Auteurs : Farida Kehal, Auteur ; M Barkat, Directeur de thèse Editeur : constantine [Algérie] : Université Constantine 1 Année de publication : 2013 Importance : 104 f.

Nutrition, Alimentation et Technologies Agro-AlimentairesTags : Crème fraîche levures bactéries huile essentielle écorce de citron analyse sensorielle Cream yeast bacteria essential oil lemon zest sensory analysis ?????? ??????? ??????? ?????????? ?????? ???????? ???? ??????? ???????? ?????? Index. décimale : 640 Industrie Alimentaire Résumé :
This study was conducted in order to enhance the lemon peel (Citrus limon) by using their essential oil as a natural agent for preservation and aromatization in cream in order to diversify the types of
existing cream on the market.
This essential oil was extracted by hydroditillation, extraction yield was 0,89 ± 0,09%. The antioxidant activity of the extracted essential oil was studied by the DPPH° test, this free radical has been effectively reduced, compared to vitamin E. These results were confirmed by the test of β- carotene bleaching.
The study of antimicrobial activity of essential oil of C. limon showed that two tested bacteria are resistant against the effectiveness of the oil, resulting in very high MICs (4% and > 8%). Regarding yeast strains isolated and tested Debaryomyces sp. and Rhodotorula sp., they have some sensitivity
to the effect of essential oil, characterized by CMI respectively 0,25% and 0,5%. The other two strains Zygosaccharomyces sp1 and Zygosaccharomyces sp2, were resistant, their MICs are respectively in the order of 1% and > 4%.
The various tests on the formulation of the added essential oil of C. limon creams were tested by developing three fresh creams with concentrations of 0,125%, 0,25%, 0,5%. Characteristics are conforms to standard. The results of physicochemical and microbiological analyzes prepared fresh cream after opening the package, show that the presence of the essential oil at low concentrations does not limit microbial spoilage. The evaluation of the oxidative stability by Schaal test indicates that the fresh cream with essential oil of C. limon are more resistant than the control opposite the forced oxidation.
Sensory analysis show that the incorporation of essential oil in the cream, at concentrations of 0,125% and 0,25%, involves no significant difference (p > 0,05) in terms of flavoring, and make products which are classified in same order than the control. Only the rate of incorporation of the essential oil of 0,5% significantly downgraded the product compared to the control in the third row, which has led to changes in smell and flavor while the texture, color and taste are unchanged. The principal component analysis (PCA) showed a negative correlation (r = - 0,998) between the levels of incorporation of the essential oil and the aroma of raw milk, and a positive correlation (r = 0,956) with the color yellow.Diplôme : Magistère En ligne : ../theses/agronomie/KEH6360.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=6352 Utilisation de l’huile essentielle de Citrus limon comme agent conservateur et aromatique dans la crème fraîche [texte imprimé] / Farida Kehal, Auteur ; M Barkat, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2013 . - 104 f. ; 30 cm.
