Phytase is an enzyme that catalyzes the hydrolysis of phytic acid (myo-inositol hexakisphosphate) into less phosphorylated myo-inositol derivatives and inorganic phosphate. It is produced by various microorganisms, plants, and animals. When associated with probiotics, these enzymes are termed as probiotic phytases. Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.
