Explain Thermal Decomposition Heating of food

Thermal Decomposition Heating of food produces various chemical changes, some of which can be important to flavour, appearance, nutritive  value and toxicity. Not only do  the different nutrients in food undergo decomposition reactions, but these nutrients also interact among themselves in extremely complex ways to form a very large number of new compounds.

The chemistry of lipid oxidation at high temperatures is complicated by the fact that both thermolytic and oxidative reactions are simultaneously involved. Both saturated and unsaturated fatty acids undergo chemical decomposition when exposed to heat in the presence of oxygen. A schematic summary of these mechanisms is shown in figure.
