How Sugarcane Becomes Sugar

The video explains how sugarcane is turned into sugar in three main phases: harvesting, milling, and distribution.

1. Harvesting

Sugarcane is a tropical grass that can grow up to six meters tall. Depending on the variety and region, it takes 11 to 17 months to mature. After cutting, the same plant can regrow and be harvested for about four years before it needs to be replanted.

Harvesting is done by hand with machetes or mechanically. Manual harvesting is now used mainly in places machines cannot reach. After cutting, the cane is transported quickly to the mill to limit sucrose losses.

2. Milling and Processing

At the mill, the cane is cleaned to remove excess soil, then crushed. Hot water is added during crushing to help extract more sucrose, producing a dark juice.

The crushed fibers, called bagasse, are burned in boilers to produce steam and energy for the process. The juice is clarified to remove most impurities while retaining the sucrose, then evaporated until about 80% of its water has been removed, leaving a concentrated syrup.

Pressure and temperature are applied to form sugar crystals. Centrifuges separate the crystals from the remaining liquid. The residue, called molasses, is fermented to produce alcohol. Finally, the crystals are dried and sorted by size before packaging.

3. Distribution

Before packaging, laboratory analyses are conducted to check the sugar’s quality. Sugar is packaged for household and mass consumption, as well as in larger sacks and containers for industrial customers.

The packaged sugar is stored in conditioned warehouses and then shipped by truck, train, or ship.

The narrator describes the process as using sugarcane by-products and generating its own energy. The video also claims that the process requires no chemicals and produces virtually no waste. It describes sugar as natural and as part of a balanced diet.
