비타민 C, chemically known as L-Ascorbic Acid, is a water-soluble vitamin and powerful antioxidant essential for collagen biosynthesis, immune system function, and iron absorption. It is commercially produced by fermentation-based processes and is available as a white to slightly yellow crystalline powder.
비타민 C is one of the most widely consumed vitamins globally, used extensively in dietary supplements, food and beverage fortification, and pharmaceutical preparations. It also serves as an antioxidant preservative in food processing, preventing oxidative degradation of fats and flavors. Various derivatives including sodium ascorbate, calcium ascorbate, and ascorbyl palmitate are available for specific application needs.
