The aim is to develop a low-cost, smartphone-assisted sensor for detecting food spoilage through biogenic amine levels.
Developed a paper-based tag (BOH@tag) for visual assessment.
Utilized colorimetric and fluorescent responses to indicate food freshness.
Employed a smartphone application for on-site monitoring.
Achieved real-time freshness assessment through colorimetric changes and fluorescence signals.
Demonstrated high sensitivity for detecting biogenic amines, indicating spoilage.
Validated the effectiveness of the sensor in various food types.

Implication

Randomized trial demonstrates a novel dual response sensor for food freshness evaluation, suggesting improved monitoring methods.

Abstract

Biogenic amines are critical food spoilage indicators, yet their on-site monitoring remains challenging. This study reports a smartphone-assisted, low-cost paper-based tag (BOH@tag) for the visual assessment of food freshness through...
