The mystery of food

Why does food go bad, and why does some food last a whole year? Follow Detective Disha as she solves the mystery of her forgotten tiffin box. Meet the tiny microbes that spoil food, find out how drying, oil and cold keep food safe, and see what each of your teeth does when you chew.
