Final answer:
In commercial sugar production, sucrose product crystals are indeed washed to remove impurities and improve crystal purity.
Step-by-step explanation:
The question pertains to whether the product crystals of sucrose in the commercial production of sugar are washed. The answer is true. In the commercial production process of sugar, after the sucrose is extracted from sugar cane or sugar beets through evaporation and recrystallization, the product crystals are indeed washed. Washing serves as an important post-crystallization step that helps to remove impurities and non-sugar materials, ensuring the purity of the sugar crystals that are presented as table sugar. Moreover, the washing process aids in reducing the color and improving the overall quality of the sugar crystals.
