In Australia, some sultanas are made without desiccant. These grapes take a long time to dry and are dark brown. They are often called "natural" sultanas.
In the United States, sultanas are called "golden raisins" or "sultana raisins ."These grapes are treated with a preservative called sulfur dioxide to maintain their bright color of the grapes.
Sultanas are usually smaller than raisins, sweeter than raisins and currants, juicy, and lighter in color. In that regard, keep an eye on the screen until we briefly discuss the health benefits of sultana and the world's major sultana exporters.

Excellent Health Benefits of Sultana Raisins
To produce sultana, the grapes must go through a different drying process. Instead of air-drying, they are soaked in the solution and go through a giant dehydrator. It only takes a few hours to dry, compared to a few weeks of natural raisins.
This faster drying process makes sultana lighter in color than natural raisins. It looks yellow instead of black or brown. They are usually smaller than natural raisins and have a juicy sweetness than raisins and currants.
The main advantage of sultana is its high fiber content, especially water-soluble fiber. A quarter cup of these dried fruits can provide about 7% of the daily dietary fiber requirement. Dietary fiber is an integral part of the diet for many reasons.
