What happens when oil is heated repeatedly?
When oil is heated repeatedly, it undergoes a series of physical and chemical transformations that significantly alter its properties. Initially, the oil heats up and begins to thin out, becoming more fluid as the viscosity decreases. This process is known as thermal oxidation, and it results in the evolution of volatile compounds that contribute to the formation of smoke and odor. As the oil continues to heat, it eventually reaches its smoke point, the temperature at which it begins to produce visible smoke when heated. Beyond the smoke point, the oil begins to decompose, releasing acrid and pungent odors as well as toxic byproducts such as polycyclic aromatic hydrocarbons (PAHs) and other hazardous compounds. This process can also lead to the breakdown of the oil’s molecular structure, resulting in the formation of carbon deposits, gum, and varnish, which can clog filters and cause equipment failure. Moreover, repeatedly heating oil can also lead to the development of thermal runaway, a self-sustaining exothermic reaction that can quickly escalate into a catastrophic fire or explosion. To prevent these detrimental effects, it is imperative to maintain proper oil filtration and replacement schedules, use high-quality oils, and avoid overheating and extended periods of idling.
Why is reusing cooking oil bad?
The act of reusing cooking oil, while seemingly economical and environmentally friendly, can have detrimental effects on both human health and the overall cleanliness and safety of kitchens.
