Abstract:
... The formation of large bubbles was observed by MRI during freezing. This was attributed to the compression of gases in a structure that cannot globally deform (due to the frozen “shell”), the consecutive rupture of dough films and the coalescence of neighbouring bubbles. The fraction occupied by these large bubbles was consistent with the hypothesis of thermal contraction, though this was not the ...
