Product Description

This method of autoxidation of the β-carotene/linoleic acid system uses linoleic acid, polyoxyethylene sorbitan monolaurate (Tween 40) and β-carotene. In the presence of oxygen, linoleic acid forms peroxyl radical (LOO^•), which reacts with β-carotene, resulting in a loss of coloration of the solution passing from bright yellow to pale yellow color. The addition of a sample containing antioxidants can react competitively with the peroxyl radical, helping to slow the drop of the absorbance of β-carotene (Jayaprakasha and Patil, 2007).

The method allows the determination of the antioxidant capacity of heat-sensitive compounds. However, it has some disadvantages, such as the difficulty of interpreting data due to the interaction of β-carotene with oxygen and reproducibility of the average absorbance values.
