Reliable determination of food components and contaminants is a crucial
necessity for a modern society. Moreover, Current food industry demands in-situ
and rapid methods with low analysis and investment costs. In this study, a portable
and low-cost LED-based optoelectronic device was developed as an alternative to
conventional spectrophotometric methods. The performance of a LED-based device
was determined by performing two common colorimetric assays as a model, namely
glucose and protein. These two colorimetric assays were performed
simultaneously with a conventional spectrophotometer, and the analytical
performance of a LED-based device was determined. Limit of detection (LOD)
values of the LED-based analysis were 1.25 mM for glucose and 0.084 mg/mL for protein
determinations. LOD values of a conventional spectrophotometer were 0.70 mM
glucose and 0.101 mg/mL protein. As a result, this low-cost optoelectronic
device has a potential as a competitive and promising alternative to conventional
spectrophotometers, and performance analysis on model assays indicates that it can
be also used for assays other than glucose and protein.
