the purpose of this study was to investigate the therapeutic effects of propolis on biochemical and microbiological parameters in muscle tissues of carp (cyprinus carpio, linnaeus 1758) exposed to arsenic. a sublethal concentration of arsenic (0.01 ppm) and/or 0.01 ppm propolis were administered to fish for seven days. biochemical parameters [ph, lactic acid, total volatile basic nitrogen (tvb-...

Quality changes of protein and non-protein nitrogen compounds during industrial fishmeal processing fatty pelagic species (mackerel/herring rest material blend, MHB) lean fish (whole blue whiting, BW) were studied to identify steps that require optimization allow production products for human consumption. Samples from protein-rich streams throughout the analyzed proximate composition, salt solu...

Meatballs were coated by gelatin-based mixes incorporated with potassium sorbate and rosemary extract. Coated samples evaluated free fatty acids (FFAs), thiobarbituric acid reactive substances (TBARS), total volatile basic nitrogen (TVB-N) content. In addition, texture profile analysis (TPA) was performed to evaluate the textural features of meatballs. Uncoated sample as control along 3 other d...

The quality of pork meat is vital since it one the most essential sources proteins and other nutrients. Near-infrared spectroscopy via colorimetric sensor array (NIRS-CSA) technology as a novel approach combined with multivariate calibrations was proposed to quantitatively evaluate total volatile basic nitrogen (TVB-N) an indicator freshness in pork. Using nine chemoselective dyes, CSA initiall...

In this study, it was aimed to investigate that the effect of drying process on rainbow trout (Oncorhynchus mykiss Walbaum, 1792) roes in terms proximate composition, aw, pH, TVB-N, TBARs, microbiological counts and color parameters. Drying lasted 42 hours including, 18 at 30oC 24 45oC. The dried fish were vacuum-packed (vacuum degree 0.02MPa) stored 4oC for 90th days. crude lipid, protein, ash...

Flesh and fatty acid compositions, total volatile basic nitrogen (TVB-N), lipid oxidation aerobic plate count, Enterobacteriaceae , psychrotrophic bacteria were determined in raw smoked mackerel during cold storage (three groups differing way of packaging; unpacked (UP), vacuum packaging (VP) modified atmosphere (MAP) at 7, 14, 21, 28, 35, 42 days. The protein, fat content n-3 polyunsaturated a...

We consider a family of high-order, weighted essentially non-oscillatory central schemes (CWENO) for approximating solutions of one-dimensional hyperbolic systems of conservation laws. We are interested in the behavior of the total variation (TV) of the approximate solution obtained with these methods. Our numerical results suggest that even though CWENO methods are not total variation diminish...
