What the texts say
Charaka calls this paka viruddha, incompatibility in cooking, one of the kinds of incompatible food he sets out in Sutra Sthana 26. Burnt food shares the line with undercooked rice, overcooked food and food cooked over bad or unsuitable fuel. All four are faults in how the food was cooked, whatever the dish.[1]
The modern view
We found no study that tests Charaka's rule as he gives it. What forms in food when it burns is a separate question for modern food-safety research, and we have not reviewed that work for this card.
