Microfluidic Devices for Food Analysis
Ramya Mohandass, Aravind Thiruvenkadam, Ashish Kapoor
The increasing outbreaks of various foodborne diseases have made food hygiene and quality monitoring a priority concern worldwide. Although traditional analysis methods are reliable, they have some disadvantages like slow rate of processing, high cost, and the need for sophisticated infrastructure. Microfluidic platforms have proved to be a worthwhile substitute for traditional methods by offering a rapid, cost-effective, and portable means of food analysis. Microfluidic platforms function based on miniaturized platforms to enable the control of minute quantities of fluids with minimal error. This chapter provides a general overview of microfluidics for food analysis, from the basics of fluid dynamics at the microscale to different propulsion and mixing platforms, and fabrication techniques like soft lithography, paper-based platforms, and 3D printing. This study examines key microfluidic platforms in the context of their applications for detecting pollutants, pathogens, and quality indicators. We further investigate the incorporation of microfluidic devices with various techniques, such as optical methods (fluorescence, colorimetry, SPR) and electrochemical techniques (voltammetry, amperometry, impedance spectroscopy). This chapter emphasizes the possibilities of microfluidic technologies to transform food diagnostics by allowing high-throughput, real-time, on-site testing, particularly in low-resource environments.
