Preserving of food was one of the crucial concerns of mankind from time immemorial. As a result drying technique has been invented and used for thousands of years by human beings.
During drying process the combined effects of air flow, air
temperature and air humidity, the water is removed from the surface
of the food. For a successful outcome from the drying
process, the relationship between these 3 factors is crucial. Since
lessening the moisture content of the produce prevent
micro-organisms from growing, the food is protected and can be
preserved for many months. In humid climates, however, moisture
uptake must be prohibited through careful packaging techniques.
We may put dried products into 3 categories:
Air-dried products: The most common type,
some products here maybe blanched or sulphured/sulphited to protect
the natural colour and help preservation.
Dried and fried products: Partly dried and then
deep-fried products are in this group. For example bombay mix and
banana chips are in this group.
Osmotically dried fruits: Fruits that are soaked
into hot and concentrated sugar syrups to extract part of the water
before it is put into drying process.
Dried/dehydrated vegetables are mostly used as ingredients by food processors, mainly from the European Union countries and the United States. Dried/dehydrated vegetables are used in the production of instant soups, sauces, dressings, ready meals, prepared products, baby food, dairy products, ready pasta dishes and pasta sauces, as well as microwave dishes and some meat and fish products. Many other dried/dehydrated vegetables are also used in various food industries.
Turkey is world`s one of the major producers of vegetables and fruits.Most of the dried/dehydrated vegetable production is oriented on tomatoes, mushrooms, leeks, carrots, potatoes, garlic, cauliflower,eggplants, squash, peas, sweet corn, okra etc...
Total production of dried/dehydrated vegetables has increased from 7.000 tons in 2000 to 20.000 tons by the year 2005 and has then been increasing parallel to foreign demand of these products.DRY FACTSDrying Vegetables and Fruits Preserving of food was one of the crucial concerns of mankind from time immemorial.
