Dried foods are those which have been processed to the point that their nutritional content has been completely destroyed. Food drying is a popular method of food preservation where food is dried using low temperatures, often by vacuum pressure or with the aid of heat. Dried foods preserve the nutritional content of food through the elimination of moisture.
Dried foods must be carefully stored away from moisture, as moisture can accelerate bacterial growth during the time it is stored. The best way to store dried foods is in a cool place, away from direct sunlight, which may cause evaporation. An air-conditioner may be used in some cases. The most convenient way of drying foods to keep them at a low humidity is an oven, as low humidity will speed up the dehydrating process. It is also important to note that low humidity causes rapid loss of nutrients during the dehydrating process soft dried passionfruit.
To store dried foods, it is important to use containers that are airtight, as air circulation can speed up the loss of moisture. Keep foods separate from one another to prevent spoilage. Also, avoid placing dehydrated foods directly on trays in the fridge, as these can cause the toppings to mold. Moisture will eventually escape into the air.
Dried fruits can benefit from being stored in a dark place, away from light and moisture. Some fruits can even be re-opened if they have been kept in dark areas for a few days. Dried foods that have been kept in dark areas for several days can retain almost all of their nutrients, but it is best to check these foods frequently to make sure they are still usable. Dried fruit can be kept in air-tight containers that have been lined with wax paper.
Dried vegetables will benefit from being stored in airtight containers. Dried vegetables can be re-opened in vacuum sealed containers, but this is not advisable for all kinds of vegetables. The best option is to freeze cut vegetables or to re-seal them in airtight containers that are labeled ‘microwave safe’ for vegetables. Keep cut vegetables in their original containers and allow them to re-heat gradually.
To prevent spoilage, store dried foods in a cool dry place. Store them away from insects and pests that can be carrying disease. If insect contamination is present, immediately remove the dried product from the area and seal tightly with a damp towel. Prevention is always better than a cure. Preventing spoilage is easy, just remember to pick up and store your products at the right time.
