Smart integrated sample preparation for rapid corn mycotoxin screening

Overview

The Smart Integrated Sample Preparation for Rapid Corn Mycotoxin Screening is an innovative bench-top platform inspired by coffee processing techniques. This solution enables near real-time mycotoxin analysis directly at corn receiving stations. By integrating grinding, extraction, and filtration into a single workflow, the system effectively addresses the bottlenecks associated with traditional mycotoxin detection methods. Operators can make quick, threshold-based decisions without the usual delays, thus reducing truck receiving bottlenecks and improving operational efficiency.

Technical specifications

Key features:

• Integrated Workflow: Combines controlled grinding, extraction, and filtration into a single bench-top unit.
• Dual Extraction Chemistries: Optimized for Polar Group mycotoxins (DON and FBs) and Broad-Spectrum Group mycotoxins (AFB and ZEA).
• Disposable Cartridges: Perform filtration and matrix cleanup to deliver a clarified extract ready for analysis.
• Rapid Assay Reading: Uses multiplex lateral/vertical flow assays with a compact digital reader.
• Scalability: Reduces manual handling, improving consistency and minimizing operator-dependent errors.

Technology readiness level

Currently at Technology Readiness Level 3, the platform has demonstrated proof-of-concept using coffee matrices. The ongoing validation process involves optimizing extraction chemistries, refining the prototype for corn, and validating with naturally contaminated and spiked samples. Future phases will focus on throughput, carryover, and operational feasibility assessments, paving the way for a next-generation fully automated platform.
