| Popis: | International audience; A dedicated setup was developed for simultaneous measurement of pressure and volume in a single eye of semi-hard cheese. A known level of gas pressure was applied to the cheese eye and the resulting eye inflation was monitored using Magnetic Resonance Imaging (MRI). Image analysis methods were developed to measure the eye volume, horizontal and vertical diameters of the eye and the deflected shape of the top surface of the cylinder of cheese under study. Two amounts of pressure were applied to attempt to reproduce a creep-recovery experiment in situ. In the last stage, lowering of pressure was applied in order to investigate time-independent elasticity. The core of the semi-hard cheese was found to show no relevant time-independent elasticity during processing in a 90 h experiment. A low amount of pressure (< 3.5 kPa) was able to inflate already existing eyes in semi-hard cheese within the linear domain. |
