Fermented was reported to have different physicochemical and functional properties to those of non fermented flour.  The objective of this research was to study the effect of spontaneous fermentation to chemical and rheological properties of corn flour and to identifying correlation among parameters.  Flour was prepared by spontaneous fermentation with variation of fermentation time (0, 12, 24, 36, 48, 60 and 72 hours).  The result indicated that the increasing of corn grits fermentation time wa
