Abstract
Phytic acid is an antinutritional factor of plant derived. foods. However, phytic acid may have protective characteristics, too. These effects can be reduced by the enzyme phytase of plant and microbial origin. The degradatio n of phytic acid results in low phosphorylated derivatives with different e ffects on mineral bioavailability. The effectiveness of phytases is greatly influenced by the conditions in the gastro-intestinal tract.
