Is everything fresh?

 

Fruit and vegetables, fish and meat, dry goods such as pasta and rice – different foods have different storage requirements. If you maintain the optimum storage temperature and keep the products in the ideal place, you can look forward to long-lasting freshness – and that’s not all. Storing food correctly in the fridge and in the larder also helps to reduce waste, protect the environment and save you money. What are the key points to bear in mind? Which foods should you not keep in the fridge, and which ones should you definitely keep there? We’re sharing some clever tips on storing food.

The basics of food storage – what goes where?

The weekly shop is done; now it’s time to put the groceries away. Many foods have specific requirements regarding storage temperature or light conditions. Some definitely need to be put in the fridge as soon as possible so as not to break the cold chain, whilst others are best kept warm. These are the basics of safe food storage:

 

  • Many types of fruit and vegetables are best stored in the vegetable drawer of the fridge to ensure they stay in good condition. These include, amongst others, broccoli, courgettes, cauliflower, carrots and leafy salads, as well as apples, kiwis, grapes, cherries, apricots and strawberries.

  • Store varieties that are sensitive to the cold outside the fridge. Typical examples of foods that are best kept warm include tomatoes, aubergines, avocados and peppers, as well as bananas, pineapples and citrus fruits.

  • Dairy products generally belong in the fridge. Only unopened long-life milk, cream and sour cream can be stored in a cool place outside the fridge.

  • Potatoes are best kept in a cool, dark place, but not in the fridge.

  • Bread and rolls stay fresh at room temperature. To prevent them from drying out or absorbing moisture, store baked goods in an unglazed earthenware pot or a wooden container. This way, it stays crisp and fluffy for a long time, without the risk of going mouldy.

  • Dry goods such as pasta, rice, flour and porridge are best stored in the kitchen cupboard. To protect them from pests, it is best to transfer the food to an airtight container.

  • Put fresh meat and fish in the fridge as soon as possible. The use-by date tells you how long you can keep the product. Tip: Ideally, you should carry perishable foodstuffs such as fresh meat in a specially insulated bag to maintain the cold chain. Alternatively, place one or two ice packs in your shopping bag.

    Use-by date vs. best-before date

    The use-by date tells you by when you should eat the food. This information is mandatory for perishable goods such as fresh meat. This should be taken into account; otherwise, there is a risk to health. With the best-before date, on the other hand, the manufacturer guarantees specific product characteristics such as taste, flavour and texture. This does not mean that the food is no longer edible after this date. Many products can still be enjoyed without any concerns even after the use-by date. The key here is to rely on your own senses and carry out the smell and taste test.

      Storing food properly in the fridge – making clever use of the different temperature zones

      Last but not least, temperature plays an important role in ensuring food is stored correctly. Traditional fridges with static cooling have different temperature zones. It’s cooler at the bottom than further up and in the door compartments. Modern versions are often fitted with forced-air cooling, also known as dynamic cooling. If this is the case, a fan distributes the air evenly throughout the entire interior. There are no longer any noticeable differences in temperature, with the exception of the door area and the vegetable drawers. Tip: Read more about how long food lasts in the fridge.

      Nevertheless, refrigeration units with recirculating air cooling also offer a range of temperature settings. Depending on the model, there may be ‘zero-degree’ zones, and it is often possible to adjust the temperature individually throughout the entire interior.


      This raises the question of what the optimum temperature is for storing food in the fridge. Experts recommend an internal temperature of around 5–8 °C for appliances with dynamic cooling. In a fridge with static cooling, you can use the different zones to optimise food storage:

        • The zero-degree zone is usually located in a separate compartment at the bottom. You can store fish, meat and sausages there at the ideal storage temperature.

        • On the bottom shelf, i.e. directly above the vegetable or zero-degree compartment, temperatures are usually between 2 and 5 °C – perfect for perishable goods. This compartment is also ideal for gently defrosting frozen food. If your fridge does not have a zero-degree zone, store sausages and meat there.

        • On the middle shelf the temperature is around 5–6 °C, which is ideal for dairy products such as cheese, yoghurt and quark.

        • At the very top of the fridge, the temperature is around 8–10 °C. This makes it the best place for sauces, tinned food and the short-term storage of prepared meals.

        • The temperature is comparatively mild in the fridge door. At temperatures of between around 10 and 15 °C, these compartments are ideal for spreadable butter, eggs, jams and tubes of mustard or mayonnaise.

          Tips on storing food

          A well-stocked larder is handy: You always have ingredients for delicious meals in the house. To ensure your supplies stay fresh until you use them up, we have something for you: These tips will help you store food successfully.

          • Store certain types of fruit and vegetables separately from one another. Apples, pears, nectarines, peaches and apricots, amongst others, release ethylene, the so-called ripening gas. This speeds up the ripening process for other varieties.

          • Move newly purchased items to the back. This makes it easier to use up older products first.

          • Freeze food (raw or cooked). This will generally extend the shelf life of meat, sausages, fish, cheese, vegetables and most cooked dishes by several months.
            Questions and answers about food storage

            Cool and dry: these conditions are ideal for most foods. The exceptions are fruit and vegetables, which stay crisp at a higher humidity. Meat and fish must always be refrigerated.

            Food can be stored in the fridge and freezer, as well as the kitchen cupboard or larder. It is best to chill fresh goods and the freezer will enable you to keep them for longer. Everything that needs a dry, cool, dark environment is best kept in a cupboard or the larder.

            A glance at the packaging will normally tell you how to correctly store the product. ‘Keep refrigerated’ refers to storage in the refrigerator at 0–8 °C, whereas ‘store in a cool place’ refers to a place outside the refrigerator at a maximum of 18 °C.

            Perishable foods like fresh meat and fish are best kept right at the bottom of the refrigerator. That is where the lowest temperatures are.

            In the vegetable drawer or on the shelf just above it.

            Sausages and cheese are best kept at the bottom of the refrigerator.

            The humidity is higher in the vegetable drawer and it is very cool. This keeps fresh goods like lettuce crisp for longer.
