What are unprocessed raisins?

Raisins that are labeled as "unprocessed" mean that they have not undergone any additional chemical or refining processes after being dried. Conventional raisins often go through a series of treatments to improve their shelf life, appearance, and texture. These processes may involve the use of preservatives, sulfur dioxide, or oils. Conversely, unprocessed raisins preserve the natural state of the fruit without the addition of any artificial substances.
