the changes in viscoelastic properties of potatoes (tubuls agria) stored at 4 ˚c for 4 months were modeled and evaluated by using the creep-recovery test. cylindrical specimens with 15 mm in diameter and 35 mm long were used. the samples were allowed to deform gradually under the constant stress (110 kpa) for about 30 min. after removing the load, the sample recovery was registered. deformation...

Background & objectives: Polyethylene terephthalate (PET) containers have many applications in the food industry. Although there are numerous advantages for PET it also has some disadvantages, one of which is the migration of materials from the container into the material inside. In this study, the effect of two factors of storage time and temperature on the migration rate was evaluated and mod...

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...

Ground cylindrical steel fluid storage tanks are widely used in different industries. Regarding the significance of these structures, it is important to establish their proper performance in earthquakes by evaluating their seismic performance. The present study examines the seismic behavior of an unanchored fluid storage system via ABAQUS after validation using an experimental model. Next, the ...
