Abstract
The use of ozonation has been discovered to increase the lutein extraction from aflatoxin-free corn and for some batches of alfalfa. In addition, the ozonation will substantially decrease any aflatoxin in the plant source. The structure of lutein as indicated by HPLC elution profile and the function of lutein using an antimutagenic activity was shown not to be affected by the ozonation.
