Cooking Oil Smoke Point and Kitchen Air Quality (Acrolein, PAHs) — household safety profile

Moderate risk

Overheating cooking oils above their smoke point generates acrolein (a potent respiratory irritant), formaldehyde, and polycyclic aromatic hydrocarbons (PAHs).

What is this product?

Overheating cooking oils above their smoke point generates acrolein (a potent respiratory irritant), formaldehyde, and polycyclic aromatic hydrocarbons (PAHs). Different oils have dramatically different smoke points: extra virgin olive oil 160-190C, refined avocado oil 270C. Chinese-style wok cooking ('wok hei') at 300C+ generates the highest concentrations. Kitchen PM2.5 during high-heat cooking can exceed outdoor air quality standards 10-100x. Range hood vented to exterior is the primary mitigation.
