Selective ion flow tube mass spectrometry (SIFT-MS) is a direct mass spectrometric technique that allows qualitative and quantitative analysis of a large number of volatile organic compounds. Because of its speed and ease of use, this nondestructive technique could be considered as a practical tool for quality control. This research focuses on the possibilities of direct headspace sampling by S...

Weight estimation of whole fish and fillets, skin color fillet meat colors the male female scaled mirror carp (Cyprinus carpio) were evaluated by image analysis. After measuring weight 10 their pictures both sides fish, side fillets taken in a light box. The relationship between (W) view area (V) was calculated linear (W = A + BV), power VB) equations. According to equation B values, carps show...

Although active mining activities in the Old Lead Belt of Missouri ceased in 1968, old tailings piles remain and continue to impact the lead (Pb) concentrations in sediments and fish in the Big River and Flat River Creek in Missouri. A 3-year study was conducted that examined the Pb concentrations in organic-rich sediments, fish fillets, and fish whole bodies at 13 sites in these two rivers. Th...

Portions of fresh Baltic cod fillets were packed into cellulose boxes (control samples), which were covered with Methyl Hydroxypropyl Celluloses (MHPC) coating with 2% polylysine. The cellulose boxes had square PE films and were enclosed in MHPC coating containing ZnO nanoparticles. The cod fillets were stored at 5 °C and examined after 72 h and 144 h storage times. Results obtained in this stu...

Quality assessment of finfish fillets during storage is important to be able to predict the shelf life of the fresh product during distribution. Microbial, chemical (pH, TMA, and TVB-N), and sensory (Quality index assessment QIA, Torry scheme) changes in vacuum-packaged blue-spotted emperor (Lethrinus sp), saddletail (Lutjanus malabaricus), crimson snapper (Lutjanus erythropterus), barramundi (...

Computer vision method was used to evaluate the color of Atlantic salmon (Salmo salar) fillets. Computer vision-based sorting of fillets according to their color was studied on 2 separate groups of salmon fillets. The images of fillets were captured using a digital camera of high resolution. Images of salmon fillets were then segmented in the regions of interest and analyzed in red, green, and ...

This study was done to evaluate the quality parameters of fresh and imported frozen seafood (fillets and shrimp). A total of 120 seafood samples, fillets and shrimp (fresh and imported frozen) 30 each, collected from fish markets at Giza Governorate were sensory, bacteriological, chemical investigated. Panelists rejected 5.0 (16.6%) and 0.0 (0.0%) of fresh fillets and shrimp samples, while the ...

in this study the effects of gamma irradiation and frozen storage on sensory, chemical and microbial quality of fish fillets was investigated. hypophtalmyctis molitrix were equally divided to 12 fillests, then these 12 fillets were equally arranged in 4 groups (1-4). one group considered as control with no treatment and the other 3 groups was treated by 0.75, 3 and 5 kgy of gamma irradiation, r...

This study aimed to evaluate the nutritional value (proximate composition, fatty acid profiles, vitamins and minerals) contents and also nutritional quality indices (NQI)) of grass carp (Ctenopharyngodon idella) prepared according to common consumer techniques: raw, poached, steamed, microwaved, pan-fried and deep-fried (in olive oil). In comparison to raw fish fillets, when grass carp was cook...
