How to prevent food from going off?
How to prevent food from going off? Many food products, in particular those that are dry, like pasta, rice or flour, do not go off even when you do not keep them in a fridge. Other products, like for example fish, should be prepared and eaten very quickly, otherwise already on the following day they go bad; one of the tell‑tale signs of that is the smell. Food goes bad usually because of very small organisms, the so‑called microorganismsmicroorganisms that live all around us. In order to prevent this process food should be stored properly. The process of food going off may be slowed down by preservation. Most products are preserved in some way. The so‑called natural preservation methods have been known for a very long time. Those methods include freezing, drying, salting and pickling, as well as making jams and marinades. Food preserved using those methods changes its flavour, but it still remains wholesome. Artificial preservatives added to food usually maintain its natural flavour, however they are believed to cause allergies, breathlessness and skin ailments if consumed in excessive quantities. You should therefore consider whether eating them is good for you.
