Sugar enzymes accelerate the conversion of starch into glucose. The conversion takes place through the processes namely liquefaction and saccharifaction. Sugarcane plant has many polysaccharides. Cellulose and hemicelluloses, present in cell wall, give the structural strength to the standing cane plant. As they are insoluble in water, consequently they do not affect sugar manufacture. Starch which is responsible for metabolic activity of a growing plant mainly occurs in sugarcane as an insoluble granule. These granules can dissolve during the processing of starch therefore they have an effect on the manufacturing process. Other soluble polysaccharides such as indigenous sugarcane polysaccharides, glucan, dextran are also detected in sugarcane plant.
