Abstract

This article focuses on the enhanced production, immobilization, and application of phytase from the fungus *Aspergillus oryzae* SBS50 for hydrolyzing phytic acid in food substrates. Using statistical optimization methods in solid-state fermentation, phytase production was increased 2.29-fold, and the enzyme was successfully immobilized in calcium alginate beads with 53% efficiency, improving its stability and reusability. The immobilized phytase retained significant catalytic activity over multiple cycles, effectively hydrolyzing phytates in wheat and pearl millet flours, thereby enhancing their nutritional quality. Safety assessments confirmed the absence of aflatoxin contamination in treated samples, supporting the enzyme’s suitability as a safe additive in food and feed industries.
