Q. Why we need Sulfuring?
Sulfuring is the process which is used to destroy microorganisms and to preserve colour. Fruits after blanching may be dipped into a sulphite solution. This process of sulfuring maintains colour of the food as it hinder the process of browning. Apples and bananas are examples of fruits that retain their colour during the process of drying if they are dipped in an acidic fruit juice or exposed to sulfuring which minimizes browning.
