It melts at 190°C-192°C and is easily soluble in water, slightly soluble in alcohol, and minimally soluble in ether, chloroform, and other organic solvents. In its solid state, Ascorbic Acid remains stable in air, though its aqueous solution can degrade when exposed to air.

In the food industry, Ascorbic Acid serves as a nutritional supplement to enhance Vitamin C content during food processing. It also acts as a powerful antioxidant, widely applied in food preservation, particularly in meat products, fermented flour products, beer, tea drinks, fruit juices, canned fruit, and canned meat. Additionally, Ascorbic Acid finds use in cosmetics, feed additives, and other industrial applications.
