Summary

Water and sugar distribution in a single blueberry were mapped both before and after freeze/thaw using magnetic resonance imaging. Freeze/thaw results in the rupture of water-retaining membranes within discrete locations of the fruit tissue. This causes a change in the ratio of motion modified water (i.e., hydrogen bonded or chemically exchanged) to unmodified (i.e., mobile and not chemically exchanged) in those regions, as well as a concomitant change in sugar concentration, due to diffusion to other tissues.
