Sugarcane Extraction

Which technique is used to separate the juice from the precipitated impurities?

• Distillation

• Clarification

• Evaporation

• Filtration

Centrifugation is used to separate

• sugar crystals from syrup

• juice from the cane fibres

• water from the sugar solution

• Precipitated impurities from sugar solution.

What is the origin of mud in sugarcane extraction?

• Soil from cane fields.

• Residue of precipitated impurities and sediments formed after filtration.

• Product remaining after sugar crystals have been removed.

• Substance found in bagasse.

What is a consequence of evaporation occuring under reduced pressure in vacuum distillation?

i. Juice boils at a lower temperature

ii. The sugar is less likely to decompose or char.

iii. the sugar taste sweeter

• i only.

• ii only.

• i and ii only.

• i, ii and iii.

Why is warm air blown onto the sugar crystals?

• To dry the crystals.

• To cook the sugar

• To process the sugar

• To form molasses
