Dried foods are those that are made into a dried form by adding an air tight container and heating it at low temperatures. Food drying is a process of food preservation where food is dried rapidly. It is done to prevent spoilage or extend shelf life. Dried foods are available in different forms such as sprouted, dehydrated, freeze dried, and air dried among others.
Dried foods are available in different forms. Sprouted dry foods are those that contain sprouts such as millet, alfalfa, buckwheat, or wheat. Dehydrated dried foods are also termed as slow moisture dried foods or instant dried foods. All these types have the same principle of being dried at low temperatures with the added benefit of air circulation.
Freeze dried fruits, for example, are made by carefully freezing some fruit then dehydrating it to make it drop its water content below 50%. These products are still preserved and go through further processing like removing any mold or fungi. The advantage of using this type of dehydrated fruit is that you do not have to worry about spoilage. However, this is not the best option for dehydrated foods since freeze dried fruit comes out of shape and hence not suitable for baking, roasting or cooking.
Dried vegetables are also good alternatives if you want to preserve them for a longer time. Vegetable soups can be prepared by drying them in low moisture environments. There are a number of drying methods for dried foods. The most commonly used method to prevent spoilage of foods is the air-flow drying process. This is one of the safest ways to preserve vegetables since no extra moisture is added during the dehydration process kingfoods russia.
Other drying methods include microwave dehydrating, oven dehydration, and freeze drying. Vacuum dehydration is also used to store vegetables and dried fruits to get rid of air pockets and retain more vitamins and minerals in the product. In vacuum dehydrating, the nutrients and moisture are pulled out of the vegetables and dried fruits by the speed of air flow. However, this process leaves behind an oily residue which does not taste good.
As much as possible, store dried fruits and vegetables in a cool and dry place. The best way to achieve this is to store them in glass containers with tight fitting lids. Plastic containers may cause the product to retain moisture and air which can cause it to spoil. Plastic containers are generally recommended for freezing purposes since they do not allow air circulation to help keep the product fresh and tasty for longer periods.
