Dried prunes are fresh plums that have been dried naturally in the sun or in a dehydrator, without undergoing any fermentation process. They are made from plum varieties selected for their high sugar content; in the USA, the most common plums for making the dehydrated fruits are grown in California. Generally, at least three or four pounds of fresh plums are required to produce a pound of the dried fruits. From the point of effective marketing, the dried prunes are often labeled as dried plums as this nomenclature seems to appeal more to buyers.
Unlike other dehydrated foods or processed foods, dried prunes do not usually contain any kind of chemical preservatives. At the most, potassium sorbate may be sprayed on the fruit to protect it from developing any mold or yeast growth. Sulfating agents that prevent darkening are not necessary and therefore not used with the prunes which are already dark.
Dried foods like prunes can be eaten directly from the packet as dried snacks. They can also be added as garnish in salads, cereals, breads, and cakes. There are many different vegetarian and non-vegetarian recipes for cooking with dried prunes, and they can make for a delicious addition to stuffed vegetables, meat dumplings, rice dishes, stews, soups, and much more. The prunes may also be added to ice cream, milkshakes, and desserts.
Like many other dried fruits, prunes are excellent for digestion. They contain soluble and insoluble fibers, and sorbitol, a natural sugar. The fibers in the prunes help with the absorption of important nutrients and in stool formation, and sorbitol promotes the growth of essential, helpful microorganisms in the intestine.
Another benefit of dehydrated fruits like prunes is that they are high in antioxidants, iron, Vitamin A, magnesium, potassium, and boron. They are excellent for maintaining healthy levels of blood sugar and cholesterol. They are also beneficial for keeping the skin well-nourished, and for slowing down the skin aging process; regular intake of dried prunes has been known to reduce the formation of wrinkles. Dried prunes are also highly recommended for people suffering from arthritis as they have anti-inflammatory properties.
Like most non-perishable foods, dried prunes can be safely stored for a long period in a cool, dry place at constant temperature. It is best to check the expiration date on the pack though when buying. A packet that has been opened should be stored in the refrigerator, and should ideally be consumed within a month.
