Vitamin C also called ascorbic acid, which was found in citrus and other fruits and vegetables.

It is used to prevent and treat scurvy.  It is a water-soluble vitamin. It occurs as a white or slightly yellow crystalline or powder.

Ascorbic acid is an essential nutrient for animals and also hunmans.  Ascorbic acid functions as a cofactor in many enzymatic 

reactions in animals that mediate a varity of essential biological funcitons, such as wound healing and cllagen synthesis.

In humans, ascorbic acid leads to impaired collagen synthesis, contributing to the more severe symptoms of scurvy, also act a role of antioxidant by donating electrons to various enzymatic and non-enzymatic reactions.

Ascorbic acid is primarily used as an antioxidant that can have many benefits for food products.

Reducing the oxidation rate preserves the color and freshness.                                                                                                                        

Low pH of ascorbic acid can help prevent microbial growth, thereby preventing shedding and maintaining freshness.                    

For these reasons, ascorbic acid is a natural active ingredient preservative.

It is used as a preservative in a wide range of food products, including jams and jellies, sauces, candies and sprays.                       

The taste of ascorbic acid should not be overlooked.

Like any acid, it tastes good in tarts, which boosts many foods. 

Candy, jam, jelly and fruit juices are often used for this flavor, which gives the consumer a distinct harvest of fresh fruit.
