4. Conclusion

Various studies on the freezing process and the quality of plant tissues have highlighted the complexity of fruit structure, and highlighted a number of operating factors, some specific to the product and others linked to the freezing process. All these factors are responsible for variations in fruit quality after freezing, the criteria for which are still difficult to identify.

The joint application of characterization methods at different scales of observation, from the macroscopic to the molecular, is an interesting approach that is becoming increasingly widespread, and necessary to monitor and better understand the impact of freezing on fruit quality. Recent years have seen many developments in terms of characterization techniques.

The development of microscopic methods, such as macro-vision and confocal microscopy, combined with image...
