Raisins are processed by sun drying and tray drying numerous different kinds of grapes. They are small and sweetly flavored with a wrinkled texture. Indian Raisins are offered in different size and colors. They have a flavor related to the grapes from which they are prepared, but the drying process which creates them concentrates the amount of sugar making them taste much sweeter. They are a logically stable food and oppose spoilage due to their low moisture and low pH.
