The influence of culinary processing on the content of phenolic and phytic acid in flint corn seeds, belonging to ten Romanian local populations, was the purpose of this paper. The biological material, used in experiments, was represented by flint corn seeds (Zea mays L. var. indurata) belonging to ten Romanian local populations. There were conducted three culinary processing of seeds (boiling, steaming and roasting,) followed by the determination of total phenolic content and phytic acid in

Thus, both the boiling and the steaming process led to the decrease of phenolic compounds and of the phytic acid in corn seeds, through thermal destruction (more) and through releasing into used waters (less), which could be the sources of such metabolites. The roasting process has generally led to significant increase of phenolic compounds, and to decrease of phytic acid.
