Calcium Ascorbate (E302) is used in the food industry as an antioxidant and acidity regulator. It helps prevent oxidation, thus extending the shelf life of food products, while also maintaining the color, flavor, and nutritional value. It is a non-acidic, buffered form of vitamin C, making it suitable for people with sensitive stomachs. Common applications include:
- Beverages: Added to fruit juices, soft drinks, and sports drinks to preserve freshness and prevent discoloration.
- Processed fruits and vegetables: Helps prevent browning and spoilage during storage.
- Baked goods: Acts as a dough conditioner to improve quality and shelf life.
- Dairy products: Can be found in products like yogurt to maintain nutritional content.
- Dietary supplements: Used in vitamin C supplements as a gentler form on the stomach, providing both calcium and vitamin C.
Calcium Ascorbate (E302) is a more stable form of vitamin C, making it a popular choice in various food preservation and fortification processes.
