Why does chocolate melt in your mouth?
Show answer & explanation
Answer: Melting point near body temp
Chemical reaction with saliva — Wrong. There's no chemical reaction between chocolate and saliva that causes melting. It's purely a physical change - cocoa butter changing from solid to liquid when heated above its melting point by your mouth's warmth.
Melting point near body temp ✓ — Correct! Chocolate's main fat, cocoa butter, has a melting point of 34-38°C, just below human body temperature (37°C). When chocolate enters your mouth, body heat causes cocoa butter to melt, creating that smooth, creamy sensation. This unique melting property is why chocolate makers carefully control cocoa butter crystallization during tempering!
Saliva dissolves it quickly — Wrong. Saliva helps with taste but doesn't dissolve chocolate quickly. Chocolate melts because of temperature, not dissolution. Cocoa butter in chocolate has a specific melting point that causes the physical change from solid to liquid.
