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...

UNLABELLED Filtered smoke (FS) has been used to preserve taste, texture, and/or color in tuna and other fish species. This treatment is particularly important in color preservation during frozen storage. The objective of this study was to compare changes in the quality profiles of FS-treated and untreated (UT) yellowfin tuna (Thunnus albacares) steaks stored in 3 ways: room temperature (21 to 2...

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...

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...

Silver carp fillets were treated with liposomal encapsulated and unencapsulated pomegranate peel extract at 0.5 and 1% w/w to evaluate the effect of the extracts on the shelf life of the fillets during 15 days of refrigerated storage. Quality changes of the samples were investigated in terms of total volatile basic nitrogen (TVB-N), peroxide value (PV), thiobarbituric acid (TBA) and microbial c...

Continuous chromatographic separator techniques have allowed the extraction of more simple sugars from molasses (MOL). The resultant byproduct, concentrated separator byproduct (CSB), has reduced readily fermentable carbohydrates but elevated CP and mineral content. The feed value of CSB was compared to that of MOL in two separate trials. In Trial 1, a chopped forage mixture containing 8 4 O/O ...

background: antioxidant activities of plant extracts are being studied to increase the shelf life of fish products. some plants such as urtica dioica l. (nettle) can be a good source of antioxidants. the objective of this study was to evaluate the effects of hydroalcoholic and water extracts of nettle leaf on the chemical properties of superchilled minced meat of the common kilka fish (clupeone...

Abstract Rabbit meat is one of the most consumed meats throughout world and extremely susceptible to spoilage due its high protein moisture content. Natural preservatives with antioxidant antibacterial properties are needed maintain quality increase shelf life. This study examined effect 1% chitosan (CH), 0.2% rosemary ( Salvia rosmarinus ) essential oil (REO), their combination on pH, total vo...
