These tomatoes are usually pre-treated with sulfur dioxide or salt before being placed in the sun in order to improve quality.  Typically, tomatoes spend 4–10 days in the sun in order for the sun-drying process to be complete.  Cherry types of tomatoes will lose 88% of their initial (fresh) weight, while larger tomatoes can lose up to 93% during the process.
