Colorimetric Paper Sensor For Spoiled Food

Colorimetric Paper Sensor

It is known that microbiological contamination is present in some foods, even if the shelf life of the products offered for sale is not expired by the manufacturer. With the Colorimetric Paper Sensor developed by NanoBiotech R&D with herbal methods, it enables instant and on-site detection of microbial degradation of packaged food products on the shelves by the manufacturer and consumer.

In the composition of the product, cellulose-based raw material, color-changing dyestuff isolated from the plant, and nanoparticles were used to increase its sensitivity.

The color change is observed due to bacterial growth. According to the color scale, the average bacterial load of the food is determined. Accordingly, it can be suggested to evaluate the consumption of food. It has been determined that the colorimetric sensor can even detect the change in ambient load within 24 hours from the production of food.

Tests and Trials

For the determination of the effectiveness of the sensor, plate chicken meat was used due to its perishability. The products with the closest production date were selected and the initial ambient flora was determined, then the sensor was integrated into the packaging and the microbial load of the meats with 24 and 48 hours and 1 and 2 days past the Expiry Date was determined.

Accordingly, it was determined that the colorimetric sensor can even detect the change in the ambient load of the food within 24 hours of production.
