Question

Why does lemon tastes sour ans tamarind tastes tangy?

Answer 1

If you've ever taken a bite out of a lemon, you already know they pack some serious sour power. This is because they contain citric acid, which is a weak organic acid found in many fruits and vegetables. True to their name, citrus fruits have particularly high concentrations of citric acid.

Tamarind is sour when the fruit is young once it get ripened it acquires a sweet and sour taste and the sourness is because of the high amount of tartaric acid present in it which is a very rich anti-oxidant agent.
