When treated with sulfur dioxide (SO₂), the color is vivid orange. Organic fruit not treated with sulfur vapor is darker in color and has a coarser texture. [5] Generally, the lighter the color, the higher the SO 2 content. Ethnic foods based on dried apricots include qubani ka meetha in India and chamoy in Mexico.
Golden raisins are treated with sulfur dioxide. Sulfur dioxide is used as an antioxidant in some dried fruits to protect their color and flavor. For example, in golden raisins, dried peaches, apples, and apricots, sulfur dioxide is used to keep them from losing their light color by blocking browning reactions that darken fruit and alter their ...
In fruit canning, sodium bisulfite is used to prevent browning (caused by oxidation) and to kill microbes. The sulfur dioxide released by these salts kills yeasts, fungi, and bacteria in the grape juice before fermentation. Once the levels of sulfur dioxide have subsided (about 24 hours), fresh yeast is added for fermentation.
Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur: S 8 + 8 O 2 → 8 SO 2 , ΔH = −297 kJ/mol To aid combustion, liquified sulfur (140–150 °C (284–302 °F) is sprayed through an atomizing nozzle to generate fine drops of sulfur with a large surface area.
Sun-dried tomatoes. Sun-dried tomatoes are ripe tomatoes that lose most of their water content after spending a majority of their drying time in the sun. These tomatoes are usually pre-treated with sulfur dioxide or salt before being placed in the sun in order to improve color and appearance. [1]

Sometimes sulfur dioxide is applied to raisins after the pre-treatment step and before drying to decrease the rate of browning caused by the reaction between polyphenol oxidase and phenolic compounds. Sulfur dioxide also helps to preserve flavor and prevent the loss of certain vitamins during the drying process. [6]
They are made from the same variety (sultana=Thompson Seedless), treated with sulfur dioxide (SO 2), and flame dried to give them their characteristic colour. A particular variety of seedless grape, the Black Corinth , is also sun dried to produce Zante currants , which are much smaller than other vine fruit, darker in colour and have a tart ...
