Is it important to measure water activity in food?

The measurement of water activity in food is of paramount importance. Water activity influences the shelf life of a product and affects texture, odour, colour and flavour. If a product is kept below a certain water activity, mould and bacterial growth are inhibited resulting in a longer shelf life.
