Coated Vitamin C

Vitamin C, CAS registry number 50-81-7, INS 300, is also known as L-ascorbic acid, ascorbate, or ascorbate monoanion & exists in the enolic form of an α-ketolactone.

It is water soluble & owes its physiological antioxidant action due its tremendous reducing action by acting as singlet oxygen quencher & capable of regenerating vitamin E.

Vitamin C is an antioxidant due to its unique ability to quench or stabilize free radicals that are generated over a period of time due to illness, lifestyle or degenerative diseases, including cancer, cardiovascular disease, cataracts, etc.

However, ascorbic acid properties are not fully exploitable due to its high reactivity, thus very poor stability in solution form. This results in decreased concentrations while processing of foods. Vitamin C is degraded rapidly in the presence of oxygen, free radicals as well as other oxidative processes. The processes are strongly catalysed by transition metal ions, especially iron & copper, leading to rapid destruction of the ascorbate anion. Oxidation of vitamin c is also accelerated at neutral pH and above & its destruction occurs in presence of enzymes like ascorbate oxidase and α-ascorbate peroxidase.

The food industry thus uses microencapsulated vitamin C to produce foods which are more nutritionally compliant & complete.

The properties of microencapsulated vitamin C allows the food processor greater flexibility & control in developing foods with high nutritional value.

Ascorbic acid is added extensively to many types of food products for two quite different purposes :

  • as a vitamin supplements to reinforce dietary intake of vitamin C, and
  • as an antioxidant, to protect the sensory and nutritive quality of the food itself.

Many technical products & processes also utilize coated vitamin C.

Microencapsulated Vitamin C in dry form is used for incorporation into cake mixes, puddings, gelatine desserts, chewing gum, milk powder, jellies, pet foods, breakfast cereals & those products which have low water activity.
