The crystal size is also affected by the rate of cooling and larger crystals were shown to be formed when fat was cooled at a slower cooling rate83. However the samples were not subjected to changes in the rate of cooling in this study. At higher temperatures (or lower supercooling conditions) due to decrease in the driving force, less crystals are formed although the crystals are larger in size as compared to those formed at lower temperatures83. At lower temperatures, due to the higher driving…
