Heat‐Induced Toxicants: Sensory Appeal Distracts Consumers' Attention From Potential Toxicological Risks of Thermally Processed Foods

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
The central paradox of thermal processing of foods. (A) The application of heat (e.g., frying, baking, grilling) to food initiates complex chemical reactions, most notably the Maillard reaction and thermal degradation of protein, lipids, and carbohydrate. (B) These reactions create a desirable sensory experience characterized by enticing aromas, golden‐
