Question

We get sugar from _________.

Answer 1

Hint: Sugars are an important source of energy with glucose being the most important for the body. Sugar is present in fruits, vegetables and green plants. It is obtained from a stem of a tall plant.

Complete Answer:
- Sugar is made in the leaves of the sugar cane plant through the natural process of photosynthesis. Energy from the sun transforms carbon dioxide and water into oxygen and glucose. The energy not needed by the plant is stored as a juice contained in the fibrous stalks of the plant.

- The harvested sugarcane is taken to the mill where it is then cleaned, shredded and pounded by rollers to separate the liquid from the fibrous material. The impurities from the juice are removed by the addition of lime and by heating the juice.
- The clear juice is condensed by boiling into syrup under a vacuum. This syrup is condensed and smaller crystals are added to it. It is then spun through a centrifuge which separates the formed crystals and dark syrup.

- Hot syrup is added to the raw sugar to soften the coating of hard molasses on the sugar. After the syrup has been mixed, it is placed through a centrifuge which removes fifty percent of the colour from the raw sugar and is then melted into liquor.
- The liquor is further purified by carbonation or phosphatation, and is then made to go through activated carbon to extract organic or other residues. Then, the excess water is collected and passed through a sterilizer with UV light. The liquid is eventually crystalized, spun through a final centrifuge, and dried. The various forms of sugar products are then produced at the refinery.

Thus, we get sugar from sugarcane.

Note: All green plants produce sugar through photosynthesis. The main sources from which sugar is obtained are sugarcane and sugar beet plants.
