Advantages

Simultaneous dual-toxin removal

Removes both patulin and ochratoxin A in the same juice system, eliminating the need for multiple treatment steps.

Applications

• juice safety control：Directly add to juice, stir, and magnetically separate to remove both toxins.
• mycotoxin detection：Simultaneously removes PAT and OTA, simplifying sample pretreatment.
• MOF-based adsorbents：Uses UiO-66 as the backbone, offering high surface area and stable binding sites.
• enzyme immobilization carriers：Covalently immobilizes PPL, retaining activity and enabling recyclability.
