Storing Fresh Produce

Some of the fresh produce we buy in the supermarket can be nearly a year old. So how do we manage to keep it fresh for so long?

Sybil Ruscoe visits a root vegetable farm in Shropshire to investigate the science of storage.

From automatically controlled storage environments to an edible protective coating for fruit - there are all sorts of tricks of the trade, new and old.
