Abstract

Effect of harvest moisture content and ambient air drying on maize fiber yield, fiber oil content and the phytosterol composition of maize fiber oil were evaluated. Maize was harvested at approximately five different harvest moisture contents (28.0, 23.0, 20.0, 18.0 and 15.0%). Effect of air drying was studied by ambient drying the maize harvested at 28.0% moisture content to 20.0 and 13.0% moisture content. Effect of both harvest moisture content and ambient air drying were significant on all the dependent variables, however, no clear trends were observed. The results suggest that as harvest moisture content goes down the amount of oil extracted from the maize fiber decreases but the concentration of the phytosterols in the maize fiber oil increases proportionally.
