Total moisture loss
The initial moisture of raw blueberries was 6.29 ± 0.02 kg·kg−1 d.w. (dry weight). During freezing/thawing, blueberries underwent several physicochemical changes that led to quality loss. Total moisture loss of approximately 1.1 ± 0.3% during freezing/thawing resulted from the inevitable loss of water vapour when blueberries were exposed to the air medium. Qualitative changes caused by sublimation and recrystallization of ice crystals resulted not only in moisture loss, but also led to the softening of blueberries, which is discussed in the next section.
