To review the nutritional and environmental consequences of seed phytic acid and evaluate the biochemical mechanisms of phytase-mediated dephosphorylation across diverse plant species.
Purified phytate globoids from cereal grains to analyze their mineral composition and evaluated dephytinization driven by wheat phytase.
Characterized the biochemical properties of purified phytases isolated from more than 23 plant species.
Compared enzymatic dephosphorylation pathways of phytic acid across different phytase classes for food and feed applications.
Phytic acid accounts for up to 80% of total seed phosphorus and 1.5% of seed dry weight, binding metallic cations such as calcium, iron, magnesium, manganese, and zinc into insoluble complexes.
Phytate predominantly accumulates in protein storage vacuole globoids located in the aleurone layer of wheat, barley, and rice, and within the embryo of maize.
Purified phytases from over 23 plant species follow distinct dephosphorylation pathways to break down phytate into inositol and bioavailable micronutrients during germination.
