Mainly we dehydrated peach and tomato to sheets and slices, while thyme and sage were dehydrated as leaves. Sheets, slices and all samples were stored and evaluated chemically periodically. We can summarize the values. from the nutritional point of view and during storage for exportation as follows.

1. Peach products I. Sugars raised 4 times of fresh fruit keeping value up to 12 months storage in dehydrated sheets and slices. 2. Drying of peach lower its contents of protein. 3. Drying of peach showed higher values in samples dried as sheets of freestone hence clingstone showed lower protein contents. 4. Vitamin C was concentrated in dried peach products. 5. According to soil and environments Sinai peach have noticeable amounts of potassium and free of heavy metals. 6. Minerals in peach products satisfY human requirements exceeding WHO limits as a new products in the Egyptian market. 7.
