Summary

Superchilling, consisting of food partial freezing up to 30% of ice prior to storage, has the potential to extend fresh food shelf life compared to chilling without the detrimental effects of freezing. The ice volume fraction and the microstructure (ice crystal size, distribution and location) define the final quality of the product.
The aim of this work was to relate changes in microstructure and quality properties of pork meat submitted to different conditions of superchilling process (partial freezing and storage). 3D microstructure evolving was characterized using X-Ray microtomography and quality properties (texture, drip loss and pH) were measured at 1, 7 and 14 of storage.
The results showed that both microstructure and quality were significantly affected by superchilling conditions. Moreover, changes in microstructure were strongly correlated to quality properties evolving. These results are valuable not only for quality control but also for the proper design of superchilling process.
