Ascorbic acid, also known as Vitamin C, is one of the most widely used antioxidants and nutritional supplements in the food industry. It functions as a potent reducing agent that inhibits oxidative browning, preserves color, and protects sensitive nutrients in processed foods. In baking, ascorbic acid serves as an effective dough conditioner that strengthens gluten structure and improves bread volume.

The compound is essential for collagen synthesis and immune function. This makes it a key ingredient in fortified foods and dietary supplements. Ascorbic acid is produced commercially through fermentation-based processes and is available in multiple grades and particle sizes for diverse food applications.
