Question

Sugarcane gur (jaggery) contains ______ % sucrose.

• A. 65 to 85
• B. 20 to 30
• C. 35 to 40
• D. 50 to 60

Hint:

Remember that jaggery is basically solidified, concentrated sugarcane juice. It's mostly sugar, so the percentage of sucrose must be high. However, it's not pure sugar, so it won't be close to 100%. The 65-85% range is the most logical choice.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Gur, or jaggery, is a traditional non-centrifugal cane sugar, meaning it is a concentrated product of sugarcane juice without the separation of molasses. Its composition includes sucrose, invert sugars (glucose and fructose), moisture, and minerals.
Step 3: Detailed Explanation:
Jaggery is a less-refined form of sugar, so its sucrose content is lower than that of white, refined sugar (which is>99% sucrose). However, sucrose is still the main component. The composition can vary based on the sugarcane variety and processing methods, but a typical range for good quality jaggery is:
Sucrose: 65-85%
Invert sugars: 10-15%
Moisture: 5-10%
Ash (minerals): 2-5%
The range of 65 to 85 % accurately reflects the sucrose content of sugarcane gur. The other options are too low.
Step 4: Final Answer:
Sugarcane jaggery typically contains 65 to 85 percent sucrose. Therefore, option (A) is correct.
