Extraction, isolation, purification, and detection techniques for phytic acid and their applications in various fields: A systematic review.

Phytic acid (PA), a phosphorus-containing compound prevalent in legumes, grains, nuts, and other seed plant materials, is extractable through methods such as soaking in an acidic solution. In the past few decades, techniques for isolating, purifying, and detecting PA have been refined to harness its antioxidant, metal-chelating, and antimicrobial properties across diverse applications. This review aims to compile the existing methods for the isolation and purification of PA, as well as its detection, and to explore its applications in numerous fields. A comprehensive search was conducted in XMOL, Web of Science, and EBSCO databases using specific search criteria. From a total of 9256 studies identified, 96 were selected for inclusion based on predefined criteria. The review details current and prevalent technologies and concentrates on the latest applications of PA across various domains, identifies existing challenges, and provides a forward-looking perspective.
