Phytate Hydrolysis in Rat Gastrointestinal Tracts, as Observed by ³¹ P Fourier Transform Nuclear Magnetic Resonance Spectroscopy

Abstract

Phytate hydrolysis was followed through rat gastrointestinal tracts by (31)P nuclear magnetic resonance spectroscopy. No phytate hydrolysis products were detected in the diet, stomach, or small intestine. It was concluded that cecal bacteria were responsible for phytate hydrolysis, which continued in the colon and fecal pellet.
