Article Synopsis
- A new paper-based vapor-test kit was developed for the real-time detection of formalin in food samples, allowing for sensitive and selective monitoring.
- The kit utilizes a microcentrifuge tube to heat samples and convert formalin into gaseous formaldehyde, which is then collected on filter paper treated with Nash's reagent, leading to a detectable color change.
- The method has a linear detection range from 0.5 to 75 mg/L and a limit of detection at 0.11 mg/L, showing high accuracy with recoveries between 92 to 111% in fresh food samples, making it suitable for food safety testing.
