What is Vitamin C?

Vitamin C (also known as ascorbic acid) is a water-soluble vitamin that is essential for the human body. It has the following core characteristics:

Necessity

The human body cannot synthesize it on its own; it must be obtained through food (such as fresh fruits and vegetables) or supplements.

Key functions

Strong antioxidant: Protect cells from free radical damage, delay aging.
Promote collagen synthesis: Maintain the health of skin, gums, and blood vessels, and help with wound healing.
Enhance immunity: Promote the activity of white blood cells, help resist infections.
Promote iron absorption: Assist in preventing iron deficiency anemia.

Consequences of deficiency

Severe deficiency can lead to scurvy (such as bleeding gums, joint pain, etc.).

Application

Food-grade vitamin C has three main core applications in the food industry:
As a nutrient fortifier to supplement vitamins, as an antioxidant to prevent food from spoiling, and as an improver to enhance the processing performance and appearance of food.
For its specific applications and main functions, please refer to the following table:

Application Category	Main function	Examples of common application scenarios
Nutritional fortification	Replenish the lost vitamin C in the food	It can be added to infant food, milk powder, fruit and vegetable juice beverages, candies, etc., or used to make vitamin C functional gummies.
Antioxidation and Color Protection	By taking advantage of its strong reducing property, it consumes the oxygen in food, preventing discoloration, deterioration in taste and loss of nutrients caused by oxidation.	– Meat products: Helps color development in ham and sausage, and inhibits the formation of nitrosamines. – Fruit and vegetable products: Prevents browning of fruit canned products and juice. – Beer/drink: Prevents oxidation to maintain fresh flavor.
Quality improvement	As a flour conditioner, it improves the processing performance of the dough, resulting in larger finished product volume and better texture.	It is added to fermented food products (such as bread and steamed buns), and the dosage is usually 0.2g per kilogram.
