The physical properties of rennet-induced coagulation of preheated camel and cow milk gels (50 and 70 °C for 10 min) enriched with calcium chloride (CaCl2) and hydrogen phosphate dihydrate (Na2HPO42H2O) were evaluated using the dynamic low amplitude oscillatory shear analysis. The storage modulus (G') and loss modulus (G") of camel milk gels showed(More)
The rheological properties of acid-induced coagulation of camel and cow milk gels following the addition of calcium chloride (CaCl2) and hydrogen phosphate dehydrate (Na2HPO4*2H2O) were investigated using a dynamic low amplitude oscillatory rheology. For a considered condition, the final values of storage modulus (G') and loss modulus (G″) of camel milk(More)
A total of 1041 asymptomatic "normal" schoolchildren in Kuwait, aged 6-16 years, were investigated over six months from November 1978 through April 1979 for hemolytic streptococcal throat carriage and for streptococcal immune response. A high carrier rate of beta-hemolytic streptococci (47%) with an unusually high prevalence of group C (32%) was found.(More)
Although being one of the most vulnerable and perishable products, fish and other seafoods provide a wide range of health-promoting compounds. Recently, the growing interest of consumers in food quality and safety issues has contributed to the increasing demand for sensitive and rapid analytical technologies. Several traditional physicochemical, textural,(More)
The growing interest of consumers in food quality and safety issues has contributed to the increasing demand for sensitive and rapid analytical technologies. Physicochemical, textural, sensory, etc., methods have been used to evaluate the quality and authenticity of milk and dairy products. Despite the importance of these standard methods, they are(More)
Mid infrared spectroscopy (MIR) combined with multivariate data analysis was used to discriminate between ewes milk samples according to their feeding systems (controls, ewes fed scotch bean and ewes fed soybean). The MIR spectra were scanned throughout the first 11weeks of the lactation stage. When factorial discriminant analysis (FDA) with leave one-out(More)
Heat treatment applied to milk induces denaturation of whey proteins, leading to a complex mixture of whey protein and whey protein coated casein micelles. The present paper investigates the effects of heat treatment (60 and 80°C during 20min) and rennet-induced coagulation temperature (30 and 40°C) determined by rheology, synchronous fluorescence(More)
Quality assessment of whiting (Merlangius merlangus) fillets stored in normal air (control group) and modified atmosphere packaging (MAP1: 50% N2/50% CO2 and MAP2: 80% N2/20% CO2) for up to 15 days at 4 °C was performed. The physico-chemical [pH, drip loss, moisture content, total volatile basic nitrogen (TVB-N), thiobarbituric acid reactive substances(More)
The objective of the present study was to evaluate the impact of rosemary and basil essential oils (EOs) on the quality of Atlantic mackerel fillets stored at 2°C up to 15 days. Atlantic mackerel (Scomber scombrus) fillets were periodically evaluated to assess their textural, color, physicochemical, and spectral characteristics. The results indicated that(More)
