Have you ever heard the theory that your tongue has different ‘zones’ that taste foods more strongly? This is a controversial Scientific theory that we put to the test today! Using a sour candy, we examined whether it tasted different when we held it on each area of our tongue. We learned that the sour taste in candy usually comes from an acid (citric, malic, or lactic).
Our questions that we will continue exploring:
-Why do people pucker their lips/close their eyes when they taste something sour?
-What is the most sour tasting candy on Earth?
-Why do we like things that taste sour or spicy, even though they might hurt or be unpleasant?
