Describe the extraction of sucrose from sugar cane? - Blurtit

Answer (1 of 2): As sugar cane is large it is hard to transport, and it is usually taken to a factory near where it is harvested in order for the extraction process to begin. Before anything can be done to the cane, it needs to be cleaned and washed to remove any impurities from the product. The next step is for the cane to be crushed, as this will extract all of the juices from it.
