Abstract
Described herein are devices for determining or monitoring the quality of a food product. In one aspect, the devices comprise a pH-sensitive film incorporated within a quick response code, wherein the pH-sensitive film is positioned to be in contact with the food product. The pH-sensitive film produces different colors subject to changes in pH of the food product. The color produced by the pH-sensitive film can then be correlated to the quality of the food product. The quick response code can provide additional information regarding the food product.
Claims20
A device for determining or monitoring a quality of a food product, the device comprising;
- at least two different color standards;
- a quick response code;
- a pH-sensitive film incorporated within the quick response code and configured to come into contact with a food product and to produce a color indicative of a pH of the food product when the pH-sensitive film contacts the food product;
- and
- a system comprising a camera configured to detect the produced color wherein the system is programmed to provide a numerical pH value of the food product by calibrating the color detected by the camera by using the at least two different color standards.
A method for determining a quality of a food product, the method comprising
- photographing the color produced by a device that is in contact with the food product, wherein the device comprises
- at least two different color standards;
- a quick response code;
- and
- a pH-sensitive film incorporated within the quick response code and configured to come into contact with the food product and to produce a color indicative of a pH of the food product when the pH-sensitive film contacts the food product;
- and
- correlating the color of the pH-sensitive film to the quality of the food product with a system comprising a camera configured to detect the produced color, wherein the system is programmed to provide a numerical pH value of the food product by calibrating the color detected by the camera by using the at least two different color standards.
