Ways Food Can Be Preserved

Duration: 2 hours

Food preservatives are added to foods to serve a specific function. Preservatives may be used to retain the nutritional value of a food or to limit the action of microbes and subsequent food spoilage e.g. by maintaining the colour and flavour of food. Typically food preservatives attack the enzymes in microbes stopping them from catalysing reactions in food, or attack the cell wall of a microbe preventing its growth and reproduction.
