Solubility

Vitamin A is soluble in fats and oils and hydrocarbons.

 

Stability

Excessive heat, light and oxygen will degrade the product.

When stored in an unopened container at 250C, approximately 0.5% loss of potency per month is expected.

Once the container is opened, the contents should be used as rapidly as possible and any unused portion padded with inert gas.

 

Storage

below 250C will enhance shelf-life but may cause crystallization of the vitamin.

Gentle warming, less than 400C, and thorough mixing before use will melt and homogenize the product.

 

During processing, the addition of an antioxidant such as dl-alpha tocopherol or BHT is recommended.

 

Application

It is the main existence form of Vitamin A in nature.

Vitamin A is essential for vision, adequate growth and tissue differentiation.
