In the context of syrup preparation, inversion of sucrose due to excessive heating may lead to
In the context of syrup preparation, inversion of sucrose due to excessive heating may lead to
Show Hint
Heat + Sugar = Hydrolysis (Inversion) $\rightarrow$ Caramelization (Dark color).
Updated On: May 15, 2026
- Syrup becomes less sweet
- Syrup dark in colour
- Sucrose crystallizes
- Viscosity less then syrup becomes solid
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Syrups are concentrated aqueous solutions of sugar (sucrose).
Step 2: Meaning
Inversion is the hydrolysis of sucrose into glucose and fructose.
Step 3: Analysis
Excessive heating causes the formation of invert sugar, which is more susceptible to caramelization. This chemical degradation leads to a darkening of the syrup's color.
Step 4: Conclusion
Overheating is avoided to prevent the "burnt" look and taste caused by sugar inversion and caramelization. Final Answer: (B)
