Sulphur dioxide is used as a sterilizing agent in making soft drinks, jams, and drying fruit because it has strong antimicrobial properties. It is effective in killing bacteria, yeast, and mold that can spoil food products. Additionally, sulphur dioxide helps to prevent oxidation and browning of fruits, which helps to maintain the color and flavor of the food products. It is also a cost-effective and efficient method of sterilization compared to other chemical agents.

Sulphur dioxide is used as a sterilizing agent in making soft drinks, jams, and drying fruit because it has several properties that make it effective for these purposes:
1. Antimicrobial Properties: Sulphur dioxide (SO2) is a potent antimicrobial agent. It inhibits the growth of bacteria, yeast, and mold by interfering with their metabolism and damaging their cellular components. This makes it effective in preventing spoilage and extending the shelf life of products.
2. Antioxidant Properties: Sulphur dioxide also acts as an antioxidant, which means it helps to prevent oxidation and browning reactions in food products. This can help to preserve the color, flavor, and nutritional value of the food.
3. Bleaching Effect: Sulphur dioxide has a bleaching effect, which can help to improve the appearance of dried fruit and jams.
4. Refrigeration Properties: Sulphur dioxide has a slight refrigerating effect, which can help to keep products cool during processing and storage.
5. Safety: Sulphur dioxide is generally considered safe for use in food preservation when used within permitted levels. It is naturally occurring and can be metabolized by the human body.
In soft drinks, sulphur dioxide is used to prevent microbial growth and preserve the flavor and color. It is typically added in small amounts to the beverage syrup before carbonation.
In jams and preserves, sulphur dioxide is used as an antimicrobial agent to prevent spoilage and extend the shelf life. It can also help to prevent discoloration and retain the natural color of the fruit.
In dried fruit, sulphur dioxide is used to inhibit the growth of molds and yeasts, which can cause spoilage and spoilage. It also helps to maintain the color and texture of the fruit during the drying process.
It's important to note that the use of sulphur dioxide as a sterilizing agent is regulated and limited in many countries. The acceptable levels of sulphur dioxide in food products vary depending on the type of product and the country's regulations.
