Changes in milk proteins effected by bacterial action are important in various aspects of the ripening of cheese and the proteolytic spoilage of dairy products in refrigerated storage. Paper electrophoresis has afforded a new method for the study of protein systems such as those in milk (MacRae and Baker, 1958; and Weigt, 1959), including the detection of certain changes occurring in such syste...

mazafati date is a wet and semi-dried date fruit type with dark red to black color that has premier quality. because of its high moisture content, date fruits of this variety are very perishable at room temperature and therefore must be refrigerated during storage. in this study, effect of air temperature (50, 60, 70, 80 and 90 ˚c) and air flow rate (1, 1.5 and 2 m/s) in hot air drying of mazaf...

Ostrich meat samples were irradiated with 0.0, 1.0 and 3.0 kGy of gamma rays, packaged under vacuum and held refrigerated for 21 days. Lipid oxidation, shear force, colour and sensory quality were determined on day 0, 7, 14 and 21. Irradiated meat showed higher values (P<0.05) for a* (redness) than the non-irradiated samples as from day 21 under refrigeration. Irradiation increased (P<0.05) the...

The objectives of this study were to evaluate the antioxidant capacity of peanut skin extract and its effect on the color and lipid oxidation of cooked chicken patties over 15 d of refrigerated storage. The extract was obtained using 80% ethanol and evaluated in terms of total phenolic content, reducing power based on the ferric reducing ability of plasma (FRAP) reagent, and 1,1-diphenyl-2-picr...

background: white button mushroom (agaricus bisporus) is one of the most sensitive agricultural crops after harvesting and its antioxidant properties tend to decrease during post-harvest storage with the passage of time. objectives: the possible role of exogenous application of malic acid as dipping treatment on bioactive components and antioxidant properties of sliced white button mushroom dur...

The study evaluated the shelf life of buffalo meat in refrigerated storage. The shelf life was evaluated for 9 days where all the physicochemical parameters were analysed on alternate days i.e. on the 0th, 3rd, 5th, 7th and 9th days. Buffalo meat was kept in polystyrene foam trays which were covered with PVC film and stored at refrigeration temperature. A significant change was recorded in phys...

A cashew nut-based beverage was obtained using broken kernels and its composition stability were evaluated during refrigerated storage for 60 days. Sensory tests performed to define the formulation, testing best proportion between water, effect of kernel roasting, ideal sweetness, attributes sensory acceptance. nut can be by grinding with water in 1:10 (m/m) added sugar at 3%, followed heat tre...
