Starch in sugar cane exist in two forms:  amilose and amilopectin. Amilose presnt a molecular weight between 100 and 1,000 D and amilopectin betwwen 10,000 and 100,000 D.

Removal of  starch from sugar products can be done enzymaticaly using alfa - amilase.

Moodley et al, 2002, refer that Carbonataion in cane sugar refineries removes 93% of starch (values obtained in lab tests).
