Sorting your purchases once you get home will help to keep your fruit and vegetables, dairy products, bread, pasta and meat fresh for longer.

Whether warm or cold, moist or dry, not all foods like the same conditions. If stored incorrectly, food will lose its flavour and spoil more quickly. This is due to the physical, biochemical, chemical and microbial influences and changes to which products are exposed. Food can also be damaged by pests and vermin.
Microbial spoilage is caused by bacteria, mould and yeasts. They cause food to rot, ferment or develop mould and sometimes develop pathogenic substances as a result. These processes and the storage life of food products depend in particular on physical conditions such as warmth, cold and moisture.
