Phytate Reduction in Bran-Enriched Bread by Phytase-Producing Bifidobacteria

Abstract

Bread fermented with the selected Bifidobacterium strains had similar technological and sensorial quality as the controls, resulting in breads with significantly lower (p < 0.05) levels of InsP(6) with residual amounts of myo-inositol triphosphates (InsP(3)). The fact that the phytate-degrading enzymes are produced by strains of bifidobacteria, which are GRAS/QPS (generally regarded as safe/qualified presumption of safety) microorganisms makes this strategy particularly suitable to reduce the content of InsP(6) in rich fiber products for human consumption.
