A raisin is a dried grape. Raisins are produced in many regions of the world and may be eaten raw or used in cooking, baking, and brewing. Raisin varieties depend on the type of grape used and are made in a variety of sizes and colors including green, black, brown, blue, purple, and yellow. Raisins can contain up to 72% sugars by weight, most of which is fructose and glucose. They also contain about 3% protein and 3.7%â??6.8% dietary fiber. Raisins, like prunes and apricots, are also high in certain antioxidants, but have a lower vitamin C content than fresh grapes. Raisins are low in sodium and contain no cholesterol. Black Raisins are sweet and delicious. These are used in preparing cookies, raisin bread, or used as just raw raisins.
