Sun Drying Process

  1. To get started, pre-process your fruit produce. Fruits with seeds should be split into two and the seeds should be removed.
  2. Light coloured fruits such as apples, pears and apricot should be soaked in lemon juice, in order to protect them from discoloration
  3. Ideally, the fruits should be cut into similar-sized pieces in order to ensure that all of them are evenly dried
  4. Use good drying racks to spread out the fruit in the tray. The racks can be made of bamboo wood or stainless steel.
  5. Place your drying racks in an area that receives bright sunshine and a cool breeze. Preferably stack the drying racks away from dust and traffic.
  6. Normally, it takes three to seven days for sunlight drying most fruits. The best practice is to let them sit out through the day and bring them back in the night.
  7. Once the food is sundried, it is important to pasteurize and condition them before storage to make sure the produce is insect-free. Here’s how:
    a) Conditioning:Take the dry fruits and pack them in a sealed container for seven to ten days. If condensation develops in the jar, then the fruit requires more drying before storage.
    b) Pasteurisation: To pasteurise in a freezer, simply store the cut and dried fruits in plastic bags in a freezer at zero degree Celsius for 48 hours. In case you want to use an oven instead, repeat the procedure by putting the sun dried produce on a tray and setting it at about 70 degrees Celsius for 30 minutes.

Sun drying is an easy process, if practiced with caution and care. There is no end to the amount of creativity and imagination that can be applied to sun dried produce during cooking. The flavour that is derived from sun dried fruits is truly incomparable to any other.
