We have discovered a new method to enhance the extraction of lutein from plant sources, involving the use of ozonation of the plant source, followed by lutein extraction using an appropriate solvent. Lutein and protein content in ozonated corn, both clean and contaminated with aflatoxin, was determined. The lutein extracted using hexane from clean ozone-treated corn was about 28.36 μg/g, which was higher than the amount extracted from non-ozonated clean corn (22.75 μg/g).
