Oxidative stability of chicken meat at different oxygen concentrations in the packaging unit

چکیده
The aim of this study was to preserve the quality and prevent colour, lipid protein oxidation in chicken breast fillet (pectoralis major muscle) during storage. For purpose, modified atmospheres (MA) with four different gas mixtures (vol. %) oxygen (O2 ), carbon dioxide (CO2 ) nitrogen (N2 were used: free (0: 20: 80), low (20: 60), medium (40: 40), high MA (70: 10). After 9 days storage a refrigerator at 2 ± 1 °C, pH measured, colour evaluated instrumentally sensorially, basic chemical composition, thiobarbituric acid reactive substances (TBARs), carbonyl content raw determined. thermal treatment (82 hour, sous-vide) fillet, sensory characteristics odour aroma evaluated, texture (Warner-Bratzler shear force) measured instrumentally. composition mixture affected all dependent parameters: (i) colour: L* b* values highest under oxygen, a* value without, high-oxygen, (ii) lipids: TBARs increased significantly after 7 (below thresholds for rancidity), (iii) proteins: MA, (iv) properties: intensity odd aromas as well stale oxygen-free increased. most suitable is packaging atmosphere without O2 , because rate lipids proteins lowest.

High dietary concentrations of methionine reduce the selenium content, glutathione peroxidase activity and oxidative stability of chicken meat
Three experiments (EXP) were conducted using two hundred seventy male chicks Ross 308 in each (90 cockerels per treatment; 3 replications, 30 chickens per pen) for 42, 38 and 35 days. The basal diets (treatment 1) for three EXPs contained the identical ingredients, and the concentration of selenium (Se), methionine (Met) and total sulphur amino acids (TSAA) in the control diet was 0.11 mg/kg, 5...
متن کاملOxidative stability of fermented meat products.
Meat and meat products, which form a major part of our diet, are very susceptible to quality changes resulting from oxidative processes. Quality of fermented food products depends on the course of various physicochemical and biochemical processes. Oxidation of meat components in raw ripening products may be the result of enzymatic changes occurring as a result of activity of enzymes originating...
