SUMMARY

Burning Gingelly oil that has already been fried does not significantly differ from burning fresh oil in terms of combustion properties, although the used oil may produce a stronger odor. The smell is attributed to the presence of acrolein, a compound released during the burning of altered oils. Understanding the chemical changes in the oil's composition is essential to grasp the reasons behind the odor and potential health implications. The discussion emphasizes the importance of chemical knowledge regarding oil degradation and combustion.

PREREQUISITES
  • Chemical composition of oils
  • Understanding of acrolein and its effects
  • Knowledge of oil frying processes
  • Basic principles of combustion
NEXT STEPS
  • Research the chemical properties of acrolein and its health effects
  • Study the process of oil degradation during frying
  • Learn about the combustion characteristics of different cooking oils
  • Investigate safety measures for burning used cooking oils
USEFUL FOR

Cooks, food scientists, health professionals, and anyone interested in the chemical properties of cooking oils and their effects on health and safety.

The Attempt at a Solution



Actually this is not a homework question. This is just my curiosity. I don't want to experiment it at my home if it is explosive or may release Carbon mono oxide.

There is no important difference between used and fresh oil when it comes to burning it. Used one can be more smelly.

What causes that smell? It must be chemically altered some where. Where is it?
 
What do you know about its original composition?

Nothing:shy:

Then even knowing how it was altered you would still know nothing.

You mean Acrolein is released when fried oil is burnt?

PS: Sorry I was inactive for a long time.
 
Have you read the linked article? Actually just a third phrase will do.
