Development of three-dimensional measurement method for ice crystals in frozen liquid foods.

Author(s) : UENO S., SAGARA Y., KUDOH K. I., et al.

Summary

A micro-slicer image processing system has been applied to observe the ice crystal structures formed in frozen dilute solutions. Several characteristic parameters were also proposed to investigate the three-dimensional (3-D) morphology and distribution of ice crystals, based on their reconstructed images obtained by multi-slicing a frozen sample with the thickness of 5 micrometer. The values of characteristic parameters were determined for the sample images with the dimension of 530 x 700 x 1000 micrometers. The 3-D morphology of ice crystals was found to be a bundle of continuous or dendrite columns at any freezing condition. The equivalent diameter of ice crystals were in the range of 73 to 169 micrometer.
