【Product Overview】
Vitamin C, also known as L-Ascorbic Acid or L-Ascorbate, is a naturally occurring water-soluble vitamin. It is a white or slightly yellow crystalline powder with a sour taste, odorless, and stable in dry air. As an essential nutrient for the human body, it serves as both a nutritional supplement and a multifunctional food additive.
Vitamin C exhibits strong reducing properties and plays multiple roles in food processing, functioning as an antioxidant, color fixative (color retention agent), flour treatment agent, and nutritional fortifier. It can be used as needed in most food categories per Good Manufacturing Practice (GMP). Its uses extend beyond the food industry into pharmaceuticals, cosmetics, personal care, and animal feed sectors.
【 Applications】
Vitamin C is one of the most widely used food additives in the global food industry. It can be used alone or in combination with other antioxidants and preservation agents to achieve synergistic effects. According to GB 2760-2024, vitamin C (CNS 04.014) is listed in Table A.2 “List of Food Additives Permitted for Use as Needed in Various Food Categories“ as an antioxidant, color fixative, and flour treatment agent. The table below provides key application categories and recommended usage levels.
