BACKGROUND Preservative effect of melanin-free extract of Sepia esculenta ink (MFESI) on Sparus latus fillet has been verified in our previous work. This study aims to further approach the mechanism of MFESI for extending the shelf-life of fish fillet during cold storage. Tilapia fillets were treated with different dosage of MFESI (0, 15, 25 and 35 mg/ml) and packed with preservative film for s...

Designs and simulations of silicon-based micro-electromechanical systems (MEMS) infrared (IR) thermal emitters for gas sensing application are presented. The IR thermal emitter is designed as a bridge-style hotplate (BSH) structure suspended on a silicon frame for realizing a good thermal isolation between hotplate and frame. For investigating the reliability of BSH structure, three kinds of fi...

An experiment was conducted to determine the effect of bird age, diet (feeds formulated with 69.5% corn, 69.7% milo, or 73.6% wheat), and feed withdrawal times (0 or 8 hours) on color (CIE L*, lightness; a*, redness; and b*, yellowness) of raw broiler breast fillets. Broilers were placed on diets at 28 d of age. Replicate groups of 24 birds (eight each from different diet and four each either f...

—A rapid genetic test to identify Pacific salmonid tissue samples to the species level is described. An exon (coding DNA) and its adjacent intron (noncoding DNA) of a major histocompatibility complex (MHC) class II gene were amplified by the polymerase chain reaction from eight Oncorhynchus species and the two Salmo species that have been transplanted to British Columbia. Among Pacific salmonid...

Increasing the combustion temperatures in a gas turbine engine to achieve higher efficiency and power output also results in high heat loads to turbine components downstream of the combustor. The challenge of adequately cooling the nozzle guide vane directly downstream of the combustor is compounded by a complex vortical secondary flow at the junction of the endwall and the airfoil. This flow t...

(2012): Comparison of farmed and wild common carp (Cyprinus carpio): Seasonal variations in chemical composition and fatty acid profile. Czech J. Food Sci., 30: 503–511. Chemical composition and fatty acid profile of fillets from farmed and wild common carp were assessed in the course of four seasons. Ten wild and ten0 farmed fis...

estimation of fillet biochemical composition and processing yield is primary needs for fish processing. present study was aimed to investigate for determining fillet biochemical composition and processing yield of bighead (hypophthalmichthys nobilis) for nutritional labeling and economical estimation of its products by regression equations. for this purpose 55 specimen of bighead were applied i...

The purpose of this study was to evaluate the effects of Scrophularia striata water extract on the quality and shelf life of the rainbow trout fillet during superchilled storage. Fish samples were treated with 1% and 3% S. striata water extract and then stored at -2°C for 20 days. The samples were analyzed periodically for chemical, microbial and sensory characteristics. Results indicated that ...

This study was performed to compare the performance of Sanita-Kun dry medium culture plate with those of traditional culture medium and Petrifilm dry medium culture plate for the enumeration of the mesophilic aerobic bacteria in milk, ice cream, ham, and codfish fillet. Mesophilic aerobic bacteria were comparatively evaluated in milk, ice cream, ham, and codfish fillet using Sanita-Kun aerobic ...

3-Trifluoromethyl-4-nitrophenol (TFM) is a pesticide used for the selective control of sea lampreys (Petromyzon marinus) in stream and river tributaries of the Great Lakes. To determine concentrations of TFM and TFM glucuronide in the edible fillet tissue of fish during sea lamprey control treatments, an analytical method was developed to determine the concentrations of these residues in rainbo...
