Food - Drying
1. List at least three different ways to dry foods.
2. Why and how do you sulphur fruits?
Commercially prepared dried fruit may contain sulfur dioxide which can trigger asthma in sensitive individuals, though dried fruit without sulfur dioxide is also available, particularly in health stores. The sulphur is added to "fix" the colour of the product. "Organic" dried fruit is produced without sulphur which results in dark fruit and the flavour is much more charecteristic of the fresh fruit. The color of some fruits can also be "fixed" to some extent, with minimal impact on flavour, by treating the freshly cut fruit with a preparation rich in Vitamin C (e.g., a mixture of water and lemon juice) for a few minutes prior to drying.
Sulphuring fruit is accomplished by burning a block of sulphur in an enclosed box (such as a dehydrator) with the fruit inside. The burning sulphur gives off sulphur dioxide which fixes the color of the fruit. This should only be done outside.
3. How is dried fruit stored and protected from insects?
As soon as it cools, dried fruit should be packed into insect-proof containers, such as glass jars or metal cans with tight-fitting lids. Do not let sulphured fruit touch metal, as this will cause the fruit to become discolored. You can pack fruit into plastic bags and then place that in a metal container. Plastic bags are not 100% insect (or rodent) proof, so make sure you store the fruit in a place where they cannot get to it.
4. How are dried foods reconstituted?
Just add water.
