The gas used in juice as a preservative, according to the provided reference, is Sulphur dioxide.
Understanding Sulphur Dioxide's Role
Sulphur dioxide is a key preservative in the food industry, particularly in beverages like juice. Here's a breakdown of its functionality:
- Antimicrobial Properties: Sulphur dioxide acts as an antimicrobial agent, preventing the growth of bacteria, yeasts, and molds that can spoil the juice. This helps extend the shelf life of the product.
- Antioxidant Capacity: It's also an effective antioxidant, preventing oxidation reactions that can degrade the quality of the juice, preserving its flavor and color.
- Prevention of Rotting: By inhibiting microbial and oxidative processes, sulphur dioxide prevents the food material, including juices, from rotting.
Why is it important?
The inclusion of sulphur dioxide in juices is essential because:
- It helps maintain the product's quality and appearance.
- It ensures the juice remains safe for consumption for an extended period.
- It reduces waste by preventing spoilage.
How is it used?
Sulphur dioxide is added to juices in carefully controlled amounts, adhering to regulations set by food safety authorities to ensure its safe use.
