Peanuts - from farm to packet
Jimmy Doherty shows a peanut plant on which the peanuts grow underground like potatoes. He highlights the concern that when they are harvested lots of other debris can be collected too. He visits a peanut factory where 2 million bags of peanuts are produced a week to find out how we only end up with peanuts in our packet. All peanuts are x-rayed and optically sorted before being fried and salted.
