AIMS To determine the utility of vacuum-packed polythene bags as a convenient, flexible and cost-effective alternative to fixed volume glass vessels for lab-scale silage studies. METHODS AND RESULTS Using perennial ryegrass or red clover forage, similar fermentations (as assessed by pH measurement) occurred in glass tube and vacuum-packed silos over a 35-day period. As vacuum-packing devices ...
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...
Background: Active antimicrobial packaging is a novel method for increasing the safety and shelf life of food products. The present study aimed to investigate the inhibitory effects of chitosan coating nano-emulsion incorporated with Zataria multiflora and Bunium persicum essential oils at the concentrations of 0.5% and 1%, respectively on E. coli O157:H7 in vacuum-packed fish samples during 12...
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 paper concerns an effect of the damping force controlling a vehicle suspension system. The investigated vehicle suspension system consists of innovatory Vacuum Packed Particles controllable dampers which allow controlling the vehicle body vibration. The main objective of performed and presented in the paper studies is to determine properties of the Vacuum Packed Particles (VPP) damper and p...
A family cluster of three cases of type E botulism were identified in south-east France in September 2009. The suspected food source of infection was a vacuum packed hot-smoked whitefish of Canadian origin purchased by the family during a visit to Finland and consumed several weeks later in France on the day prior to symptom onset. No leftover fish was available to confirm this hypothesis. Vacu...
The objective of this study was to gather data on the incidence of Clostridium botulinum spores in selected consumer-convenience food products. The incidence of spores of C. botulinum in 100 samples of each of four categories of commercially available convenience foods was determined. These categories included (i) "boil-in-the-bag" foods, (ii) vacuum-packed foods, (iii) pressurized foods, and (...
