It shows a continuous mass decrease for the frozen bread, reflecting the loss of the crumb water that migrated outside and formed surface ice crystals.
- shows that the frozen bread stored as half-cut specimens featured faster loss of crumb water than that stored as whole pieces.
(The half-cut specimens are smaller in size, hence larger in surface-to-volume ratio, roviding shorter routes for crumb water to migrate out and the partial loss of crust for the half-cut bread, which would otherwise function as a natural barrier against the escape of water. )
