Partitioned-amplification with capillary electrophoresis for salmonella detection in food

Overview

The Partitioned-Amplification with Capillary Electrophoresis (PACE) platform represents a groundbreaking approach to food safety testing, specifically tailored for the detection of Salmonella spp. in challenging food matrices such as chocolate. By leveraging droplet-based partitioning and capillary electrophoresis, PACE achieves high-multiplex, single-copy sensitivity, making it uniquely suited for environments where pathogen loads are low and PCR inhibitors are prevalent. This technology promises a streamlined, cost-effective solution, delivering results in less than 4 hours, thereby enhancing food safety protocols and regulatory compliance.

Technical specifications

Key features:

• High Sensitivity: Achieves a detection limit of 1 colony-forming unit (CFU) per 375 grams of product.
• Rapid Results: Provides time-to-result in under 4 hours through an integrated workflow.
• Scalability: Designed for adaptation to various food safety contexts and regulatory frameworks.
• Specificity and Robustness: Utilizes Salmonella-specific primers and thermal lysis for accurate detection.
• Cost-Efficiency: Optimization of pre-enrichment, filtration, and DNA extraction reduces operational costs.

Technology readiness level

The PACE platform is currently at Technology Readiness Level 3, indicating that it is in the stage of active research and development with key concepts having been validated in the laboratory. Future efforts will focus on optimizing sample preparation and validating detection methods with live and synthetic DNA samples.
