Abstract

Processes and methods for producing dried fruit which has been treated with sulphur dioxide. Such processes and methods are particularly adapted for producing golden raisins which have relatively low concentrations of sulphur dioxide. To produce golden raisins, fresh sultana grapes are subjected to sulphur dioxide fumigation before undergoing a series of washing and rinsing steps which may include a cold water bath, a hot lye bath, and cold water sprays before being placed into drying tunnels. After drying, golden raisins may be undergo an additional treatment of sulphur dioxide.

Claims (3)

1. A dried grape having a moisture content of less than about 20% and more than about 10% and a sulphur dioxide concentration of between about 100 and about 1000 ppm.

2. The grape of claim 1 , wherein said grape has a sulphur dioxide concentration of between about 100 and about 750 ppm.
