ClearDetection methods of micro and nanoplastics
This review surveyed current detection methods for micro- and nanoplastics across environmental and food matrices, comparing techniques like FTIR, Raman spectroscopy, and mass spectrometry for identifying these emerging contaminants.
Methods for identifying microplastics in food systems
Identifying microplastics in food is technically challenging because food matrices are complex and particles can be very small. This review covers the main methods scientists use — from simple visual inspection to sophisticated techniques like Raman spectroscopy and infrared imaging — and evaluates their strengths and limitations in the context of food safety. The authors conclude that Raman microscopy and Fourier-transform infrared spectroscopy are currently the gold-standard approaches for detecting and confirming the chemical identity of microplastics in food and agricultural products.
