There are three main methods to preserve the fruits:
1 Drying- the majority of the original water content has been removed either naturally, through sun drying, or through the use of specialized dryers or dehydrators.
2 Freezing - s a method of preserving fruits in which the fruits contents are processed and sealed in an airtight container. Canning provides a typical shelf life of several years.

Drying fruit such as grapes and apricots removes most of the water-soluble B and C vitamins, but minerals such as zinc, iron, potassium and calcium become more concentrated - you get 4mg of iron from three dried apricots as opposed to 20 fresh ones.;
Freezing fruits locks their nutrients in. The freezing process itself destroys some vitamins, but these are lost naturally with exposure to light and air, so frozen peas will have comparable levels to fresh peas that were picked three weeks earlier. While canning retains some nutrients such as iron, it removes fibre - important for fat loss - so ifs best to stick to the other types.
