Purification of Sucrose: Quicklime is used to precipitate impurities, aiding in the extraction of pure sucrose from sugar juice.

pH Regulation: It increases the pH of raw sugar juice from acidic to neutral, creating optimal conditions for the removal of impurities.

Color Removal: Quicklime assists in removing colorants from sugar juice, resulting in a clearer and whiter final product.

Impurity Removal: By causing impurities such as calcium carbonate and magnesium hydroxide to precipitate, quicklime makes them easier to filter out.

Wastewater Treatment: Quicklime is added during the sugarcane washing process to treat effluents, reducing environmental impact.

Lime Production in Sugar Refineries: Quicklime is produced by burning limestone in limekilns at sugar refineries. The process also generates carbon dioxide, which is reused in sugar refining.
