Q1:

Sucrose content in cane sugar may be around __________ percent.

A 50

B 70

C 80

D 95

ANS:D - 95

Sucrose content in cane sugar may be around 70 percent. The sucrose content in cane sugar may be around 70 percent for several reasons:

1. Composition of Sugarcane:

  • Primary Component: Sugarcane is primarily composed of sucrose, which is the main sugar extracted during processing. Typically, the sucrose content in mature sugarcane ranges from 10 to 15%, but the extracted sugar product can be concentrated to about 70%.

2. Refining Process:

  • Purification and Concentration: During the sugar extraction and refining process, impurities and non-sugar components are removed, resulting in a high concentration of sucrose in the final product.

3. Yield from Processing:

  • Extraction Efficiency: The processes involved in sugar extraction, including crushing, juicing, and purification, are designed to maximize the recovery of sucrose from the cane, leading to a concentrated product.

4. Standard for Commercial Sugar:

  • Commercial Grade: The 70% sucrose content is typical for raw and refined cane sugar used in food production, making it suitable for various applications in the food industry.

Summary:

In summary, the sucrose content in cane sugar is around 70 percent due to the high concentration of this sugar in sugarcane, effective extraction and refining processes, and its status as a standard for commercial sugar products.
