This study was performed to improve the techniques used for tenderizing red meat as elderly food. Beef meat was immersed in liposome encapsulated enzyme solution and the effect of protease encapsulation on the beef properties was analyzed. The protease encapsulation properties were analyzed according to the size distribution and enzymatic activity. After enzyme reaction on the beef, the chemica...

Han F., Huang X., Teye E., Gu H., Dai H., Yao L. (2014): A nondestructive method for fish freshness determination with electronic tongue combined with linear and non-linear multivariate algorithms. Czech J. Food Sci., 32: 532–537. Electronic tongue coupled with linear and non-linear multivariate algorithms was attempted to address the drawbacks of fish freshness detection. Parabramis pekinensis...

Total Volatile Base Nitrogen (TVB-N) and Trimethylamine (TMA-N) contents of Vetki (Lates calcarifer) were investigated following Conway’s Microdiffusion technique at 4 hour interval in Fish Quality Control Laboratory, Fisheries Marine Resource Technology Discipline, Khulna University. Observed TVB-N TMA-N value did not vary significantly among different size classes. At fresh condition, content...

We investigated the effects of tea polyphenol treatments on quality and microbiota crisp grass carp fillets during cold storage at 4 °C. Changes in total viable count (TVC) volatile base nitrogen (TVB-N) were measured. The was analyzed using high-throughput sequencing technique. results indicated that inhibited bacterial growth reduced TVB-N values fish fillets, subsequently extended their shel...

 Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after exposure to propolis and cypermet...

The determination of total volatile bases (TVB) is probably the oldest objective chemical method for assessing the spoilage of fishery pro­ ducts. It was proposed about a century ago and was already published as standard method for the inspection of fish in Germany in the first years of this century (KÖNIG, 1910). This simple method is still widely used. A European Union directive on fish hygie...

the present work was carried out to study the effect of vacuum packaging and pomegranate peel extract (pe) treatments on the quality of pacific white shrimp (peneous vannamei) during refrigerated storage. changes in ph, thiobarbituric acid (tba), total volatile base nitrogen (tvb-n), trimethylamine (tma), aerobic plate counts, psychrophilic, lactic acid bacteria and enterobacteriaceae counts, m...

Volatile organic compound (VOC) profile was determined during storage of sea bream (Sparus aurata) fillets under air and Modified Atmosphere Packaging (MAP - CO2/O2/N2: 60/10/30) at 0, 5 and 15°C. Microbiological, TVB-N (Total Volatile Base Nitrogen) and sensory changes were also monitored. Shelf-life of sea bream fillets stored under air was 14, 5 and 2days (d) at 0, 5 and 15°C respectively, w...
