Effect of osmotic dehydration on Actinidia deliciosa kiwifruit: A combined NMR and ultrastructural study

► Kiwifruit structural modifications promoted by osmodehydration were studied. ► An innovative multianalytical approach (LF-NMR, LM, TEM) was used. ► Osmotic dehydration caused water redistribution among cell compartments. ► Vacuole shrinkage and intracellular space formations were detected. ► Changes in cell wall structure were comparable to those associated with fruit ripening.
