A multiple processing hybrid flow system for analysis of formaldehyde contamination in food.
This work proposes a flow system suitable for the rapid screening of formaldehyde contaminated in food. The system is based on the concept of a flow analyzer with a Hantzsch reaction. An operating procedure was developed for multiple tasking and high sample throughput. This resulted in a significant sample throughput of 51 samples h(-1). Under the optimized conditions, linear calibration from 10 to 100 microM was obtained. The system gave a limit of detection and a limit of quantitation of 0.06 and 0.10 mg kg(-1), respectively. The system was successfully applied to re-hydrated dry squids, vegetables and mushrooms.
