Method for manufacturing sugar from sugarcane

A method for manufacturing sugar from sugarcane, the method consisting of steps of:

• dosing biocides on sugarcane during cane preparation for cane sanitation and milling for mill sanitation;
• heating the juice at 70° C.;
• subsequently, neutralizing the juice;
• subsequent to the neutralizing step, heating the neutralized juice to about 105° C.;
• subsequent to the neutralizing step, adding amine polymers in the neutralized juice to effect solid settling;
• concentrating the neutralized juice by evaporating to boil off water to obtain syrup of the neutralized juice having about 60% solids;
• crystallizing the syrup, obtained in the concentrating step, to obtain a liquor;
• and
• separating sugar from the liquor obtained in the crystallizing step;
• and
• washing and drying the sugar;
• whereby a sulfitation step is short-circuited to produce sugar containing substantially zero amount of sulfur.

• adding viscosity reducers to reduce viscosity of the syrup;
