What Are Raisins?

These small but mighty raisins are produces from grapes (Thompson seedless grapes). These grapes are arraigned on brown craft paper trays and placed between vineyard rows.

This allows the sun to dry them. The natural sun-drying process is what turns grapes into raisins. During this process, the oxidation and caramelization of sugars take place and result in a raisin’s natural dark brown or black color.

Apart from sun-drying, raisins can also be produced by water-dipping or they can be dehydrated artificially. This drying process preserves the antioxidants and concentrates the nutrients in raisins.
