Pangasius catfish (Pangasianodon hypophthalmus) is popularly cultured in Bangladesh but the farmers usually suffer financial losses due to their low market price. Development of new value-added products will enhance its popularity and acceptability consumers. This study was conducted develop smoked from pangasius catfish, evaluate quality shelf-life at ambient (30-35°C) refrigeration temperatur...

Atlantic horse mackerel (Trachurus trachurus) fillets were coated by gallic acid and chitosan solutions, including nanoparticles, fish quality shelf life assessed during chilled storage for 13 days. All chitosan-containing coatings decreased microorganisms’ growth in more than 2 log cycles up to late stages; however, those with nanoparticles resulted be effective, probably due a greater contact...

This study was done to evaluate the antimicrobial and antioxidant effects of nisin Z (0.02 %) and sodium benzoate (1.5 and 2.5 %) in vacuum packed Caspian Kutum (Rutilus frisii) fillet stored at 4°C. Microbial changes [aerobic plate counts (APC), psychrotrophic counts (PTC) and lactic acid bacteria] and chemical indices [peroxide value and total volatile basic nitrogen (TVB-N)] were determined ...

The chemical compounds of kaffir lime leaves oleoresin and the preservative effects of kaffir lime leaves oleoresin incorporation on cassava starch-based edible coatings for fresh beef during 14 days refrigerated storage were investigated to determine their ability to extend beef shelf life. Beef characteristic was determined based on microbiological (Total Plate Count/ TPC), chemical (Total Vo...

FT-NIR was evaluated as a method to analyze 16 components (analytes) in tobacco. For each component, spectra of 578 to 785 samples were utilized respectively as calibration samples to develop the calibration model. For all calibrations, the raw spectra were pretreated as first derivative, and Partial Least Square (PLS) was used as the calibration algorithm. About 50 randomly selected validation...

Optimal packaging and storage conditions for fresh tilapia fillets were established by evaluating sensory and microbiological changes, as well as monitoring physicochemical properties. Nile tilapia (Oreochromis niloticus) farmed in recirculation aquaculture system was filleted, deskinned, and packaged in air and 50% CO2/50% N2 prior to chilling and superchilling storage at 1°C and -1°C. Sensory...

Sumac (Rhus coriaria L.), belonging to the Anacardiaceae family, grows in Mediterranean countries, North Africa, South Europe, Afghanistan and Iran. The sumac berries contain biological activities such as antioxidant, antimicrobial, hypoglycemic and antidiabetic. The present study examined the effects of water extract of sumac on the chemical, microbiological and sensory quality on silver carp ...

PURPOSE We evaluated the influence of prior maximal exhalation on preoxygenation in 15 adult volunteers using tidal volume breathing (TVB) for five minutes and deep breathing (DB) for two minutes with and without prior maximal exhalation. METHODS Inspired and end-tidal oxygen, nitrogen and carbon dioxide were monitored continuously and recorded during room air breathing and at 30-sec interval...

One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7. Quorum-sensing (QS) signals (N-acyl homoserine lactones (AHLs)) were detected by report strains and their structures were further determined by GC-MS. The activity changes of AHLs on strain growth stage as well as the influence of diff...
