WebAug 15, 2012 · The higher consumption of dextrose increases crystal formation MT and hence the exponent m is higher for 4% impurities. For 7% impurities, crystal formation is 3.8% lower and it is 10.1% lower for 11% impurities; hence, the lower amounts of crystal formation decrease m for both 7% and 11% impurities.
