Sun is Shining: Solar Energy and Agriculture
Dried fruit is a delicious and nutritious
snack, and is a good complement to other dishes. Use it to top ice cream or
cereal, or add it to cakes. Dried fruit tastes sweeter than fresh fruit because
the water has been taken out of it, which makes the flavor of the fruit
concentrated.
Using a dehydrator with solar energy is perhaps the most
convenient and environmentally friendly method of drying fruit.Using solar heat
for drying has become popular because it is especially well suited for delicate
crops, and will not burn or harm produce, which may happen with steam heated or
fossil-fuel heated air. These systems are effective and cost-efficient in other
process drying and heating applications.
Drying removes the moisture from the food so bacteria, yeast and mold cannot grow and spoil the food. Drying also slows down the action of enzymes (naturally occurring substances which cause foods to ripen), but does not inactivate them.
In drying, warm temperatures cause
the moisture to evaporate. Low humidity allows moisture to move quickly from
the food to the air. Air current speeds up drying by moving the surrounding
moist air away from the food. Because drying removes moisture, the food becomes
smaller and lighter in weight. When the food is ready for use, the water is
added back, and the food returns to its original shape.
Some advantages of
solar dried fruit:
- Drying is a low-cost way to preserve food
- Dried foods retain more of their nutrients than bottled or canned foods
- Dehydrated fruits require less storage space than bottled or canned goods
- Storing the dehydrated foods does NOT require electricity
