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...

The freezing-thawing effect on the meat quality of whole, gutted and fillets of sea bass (Dicentrarchus labrax) were investigated. It was aimed to investigate the changes in the meat quality of whole, gutted and fillets of sea bass in multiple frozen (-18±2ºC) and thawed cycles in refrigerated conditions (4±2°C). The meat quality assessment of the sea bass groups (whole, gutted and fillets) sub...

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...

in this study, the extract of sea cucumber species, holothuria leucospilota was extracted and its effect studied on the chemical quality rainbow trout fillets packed in vacuum. sea cucumber was extracted using methanol and various concentrations (0, 5/0, 1 and 2%) were prepared. salmon fillets after soaking in the extracts were vacuum packed, chemical tests every 4 days included total volatile ...

The transcription factor Blimp-1 has emerged as a regulator of cell fate in embryonic (germ cell) and adult (B- and T-cell immune effector and epithelial) lineages. It has also been proposed to act as a tumor suppressor in B-cell malignancy. Here, we present a novel in vivo system enabling the targeted genetic manipulation of cells expressing Prdm1, the gene encoding Blimp-1. We created bacteri...

in this study, the effect of green tea extract was studied on quality of surimi produced from fish silver carp during refrigerated storage. surimi was prepared and immersed with various concentrations of tea extracts (0, 2 and 4%). samples were refrigerated for 15 days and were performed chemical tests include ph, total volatile bases nitrogen (tvb-n), thiobarbitoric acid (tba) test and total b...

Successful targeting methods represent a major hurdle to the use of retroviral vectors in cell-specific gene-delivery applications. We recently described an approach for retroviral targeting with a retroviral receptor-ligand bridge protein that was bound to the cognate cell-surface ligand receptors before viral challenge. We now report a significant improvement made to this viral targeting meth...

An intelligent pH-sensing indicator containing Roselle (Hibiseus sabdariffa L.) (RS) anthocyanin and curcumin (CR) was developed characterized as on-package tags to check the freshness of shrimp during storage at 4°C. FE-SEM FT-IR analysis showed that RS CR were successfully immobilized in gelatin–glycerol film-forming substrate. The addition various natural dyes increased thickness antioxidant...
