I am a supplier of all kinds of raisins, golden and sultana raisins, green and yellow kashmiri for export.
Sunny raisin is a ripe seedless grape fruit, which is dried by direct sunlight for 15 days and changes its color and turns brown.
Sultana raisin is also produced from seedless grapes. First, we put it in acidic material for ten seconds. Then we spread it under the sun for a week, it dries, and it turns from date to golden color.
Golden raisin is made from seedless grapes. This raisin is dried by sulfur smoke and has a bright golden color. It is useful for the strength of teeth and bones.
