| Abstract: | X-ray micro-computed tomography
(XMT) system, a novel technique which has been
developed for visualisation of the two- (2-D) and
three dimensional (3-D) ice crystal structures
formed during freezing of strawberry and jackfruit.
The system reconstructs all 3-D images based on a
set of 2-D imaged obtained by multiple slicing of
an X-ray shadow image. This study demonstrates
the capability of the technique to characterize the
ice crystal microstructure of strawberry and
jackfruit after freezing at -20oC. Results are
presented for the 2-D ice crystals formed within
strawberry and jackfruit. The method requires
freezing of the sample under -20oC and freezedried
before scanning indicating ice crystal and
internal structure of the strawberry and jackfruit at
1 cm depth. The dendrite spacing of ice crystals
has been related to the freezing conditions of the
strawberry and jackfruit |
