Abstract

Certain strains of lactic acid bacteria and yeasts have demonstrated remarkable effectiveness in degrading mycotoxins through mechanisms such as physical adsorption, enzymatic transformation, and inhibition of toxin biosynthesis. This investigation evaluated the efficacy of five postbiotics derived from probiotic strains and from Candida utilis 22023 in removing patulin from apple juice. Juice samples were artificially spiked with a high dose of patulin (1000 ng/mL). Additionally, the physicochemical properties and vitamin C content of the juice samples were determined over 48 h. Results showed that Candida utilis 22023 postbiotic reduced patulin by >79.14% within 48 h, while other strains achieved reductions ranging from 62.64% to 78.77%. Physicochemical analyses revealed a significant decrease in pH after 48 h of storage, and vitamin C levels in apple juice varied over time. Consequently, our findings demonstrate that these postbiotics are effective candidates for controlling patulin contamination while maintaining juice quality. © 2026 The Author(s).
