Food & Senses

What you taste, smell, feel

Taste is chemistry meeting nerve endings. The "heat" of chili isn't temperature — it's capsaicin firing pain receptors that evolved to warn you about burns. Wasabi's bite is allyl isothiocyanate hitting the same channel. The umami in MSG is a glutamate ion clicking into a receptor first cloned in 2000. This collection unpacks the molecules behind flavor, aroma, mouthfeel, and even color: vanillin (mostly synthetic now), curcumin (turmeric's yellow), allicin (garlic's bite, only after cutting), the four artificial sweeteners that lit up the diet-soda wars. Food is just chemistry you're voluntarily eating.
