ANS:B - 5 to 10

The correct answer is: 20 to 30

Explanation:

Sugar content in sugarcane is typically about 20 to 30 percent by weight, which makes it a valuable source for sugar production. The sugar content in sugarcane, typically ranging from 20 to 30% by weight, is significant for several reasons:

1. Composition of Sugarcane

• Sucrose Concentration: Sugarcane primarily contains sucrose, a disaccharide, which accounts for the majority of its sugar content. This high concentration is what makes sugarcane an ideal raw material for sugar production.

2. Economic Importance

• Sugar Production: With a sugar content of 20 to 30%, sugarcane is economically viable for large-scale sugar production. This concentration allows for efficient extraction processes in sugar mills.
• Byproducts: In addition to sugar, sugarcane can be processed to produce byproducts like molasses, bagasse, and ethanol, all contributing to its economic value.

3. Variability Factors

• Environmental Influence: The sugar content can vary based on factors such as climate, soil type, and agricultural practices. Optimal conditions can lead to higher sugar yields within this range.
• Cultivar Differences: Different sugarcane varieties may have varying sugar content, but most commercially grown varieties fall within the 20 to 30% range.

4. Harvesting and Processing Implications

• Harvest Timing: The sugar content can influence the timing of harvesting. Higher sugar levels are usually desirable, leading to strategic decisions on when to harvest for maximum yield.
• Processing Efficiency: The sugar content directly affects the efficiency of extraction processes in sugar mills, influencing the overall yield and profitability of sugar production.

Summary

A sugar content of 20 to 30% in sugarcane is crucial for its role as a primary source of sugar. This range ensures economic viability, influences agricultural practices, and impacts processing efficiency in the sugar industry.
