Keep Apples Crisp: Top Storage Tips from Experts
To keep apples crisp and flavourful, various organisations and experts recommend several storage tips. Here are some general guidelines often suggested.
Apples should be stored in a cool and dry environment, ideally between 0 and 5°C with a relative humidity of about 80 to 90%. They should be kept away from direct sunlight to prevent colour changes. Good air circulation is crucial to reduce moisture and prevent mould growth. Damaged or bruised apples should be removed regularly.
For professional storage, controlled atmosphere (CA) is often used to reduce oxygen levels and prevent bacterial and fungal growth. However, this method is not suitable for home use. Organisations like the Bayerische Landesanstalt für Landwirtschaft (LfL) and other agricultural institutions in Germany provide detailed information on apple storage. The Deutsche Ernährungsberatungs- und Informationsnetz e. V. (DGE) may also offer advice on food preservation.
For optimal storage, use small, well-ventilated boxes to store apples in a single layer, barely touching each other. Apples release ethylene, which speeds up the ripening of other fruits and vegetables, so it's best to store them separately. To maintain freshness, pick apples by hand and store them immediately in containers, handling them as little as possible.
Following these storage tips can help maintain the quality and freshness of apples. Professional advice and specific requirements for certain apple varieties should also be considered for optimal results.
