Researchers of which IIT have developed an ultrasound-assisted fermentation method to produce a safe sugar replacement called "Xylitol" from bagasse in August 2022?

Correct option is D

Researchers at IIT Guwahati have developed an ultrasound-assisted fermentation method to produce Xylitol, a safe sugar substitute, from bagasse. Bagasse is the fibrous residue left after extracting juice from sugarcane. The new method is an improvement over traditional chemical synthesis, addressing challenges like inefficiency and high environmental impact. By incorporating ultrasound waves, the fermentation process becomes faster and more effective, overcoming time delays and operational limitations of conventional methods.

This innovation has significant implications for sustainable food production, utilizing agricultural waste and offering a healthier sugar alternative.
