Product Description
Ascorbic Acid, commonly known as Vitamin C, is a water-soluble, naturally occurring organic compound with potent antioxidant properties. It appears as a white to slightly yellow crystalline powder, has a sharp acidic taste, and is highly soluble in water. While abundant in citrus fruits (e.g., oranges, lemons) and vegetables (e.g., broccoli, peppers), ascorbic acid is commercially synthesized via fermentation (e.g., from glucose) for industrial use. It plays a vital role in human health, supporting collagen synthesis, immune function, and iron absorption. Beyond healthcare, it is widely utilized in food preservation, cosmetics, and technical applications due to its reducing and stabilizing capabilities.
