Capsaicin Chemistry: Why Boiling Chilis Weaponizes a Kitchen
Boiling chilis aerosolizes capsaicin oil droplets (not dissolved in steam). Distillation would purify spicy water because capsaicin boils at 210°C vs water's 100°C — it stays behind.
Boiling dried chili peppers essentially creates homemade pepper spray. The capsaicin becomes aerosolized — not by dissolving in steam, but through a different mechanism. Capsaicin is fat-soluble, not water-soluble, and has a boiling point of ~210°C (much higher than water's 100°C). So it doesn't evaporate WITH the water. Instead: 1. Heat volatilizes capsaicin compounds directly from the chili material 2. Tiny droplets of capsaicin-containing oils become suspended in the steam as an aerosol 3. This aerosol fills the enclosed space and irritates eyes, lungs, and skin Survival application: If you had capsaicin-contaminated water and needed to purify it, distillation (boiling and collecting the condensed steam) WOULD work. Since capsaicin's boiling point is far above water's, it stays behind in the original vessel while clean water vapor condenses in the collection apparatus. The collected distillate would be capsaicin-free. This same principle is why distillation separates substances by boiling point — compounds with different boiling points can be separated by controlled heating.
