were performed by cooling down from 42 to 33 C in 24 h. During the crystallization trials, seeding was performed at 42 C in a supersaturated solution. Three sets of crystallization trials were performed. In the first set of trials, the three syrups with 67.5% dextrose concentration were used to investigate the influence of impurity level. In the second set, the influence of seed size was investigated. The seed crystals were sieved to obtain sieve fractions which had median chord lengths of approximately 125, 155 and 220 lm. These were used to seed dextrose syrups with 65.5% dextrose. The third and final set of trials investigated the influence of initial dextrose concentration where syrups with 65.5% and 67.5% dextrose and 7% impurities were used
