<i>Peniophora lycii</i> phytase is stabile and degrades phytate and solubilises minerals <i>in vitro</i> during simulation of gastrointestinal digestion in the pig

Abstract

Stability of P. lycii phytase during gastric digestion was not found to be critical for phytate hydrolysis. Furthermore, original phytate solubility was not an absolute requirement for phytate degradation; phytate solubility seemed to be in a steady state, allowing insoluble phytate to solubilise as soluble phytate was degraded. This is new and interesting knowledge that adds to the current understanding of phytate-phytase interaction. Copyright © 2007 Society of Chemical Industry.
