The plurality of color patches 20 are generated according to a colorimetric sensor array sensing the food product, and the colorimetric sensor array includes a plurality of sensing materials for sensing the food product. The plurality of sensing materials respectively react with at least one metabolic molecule of the food product to change from an initial color to an indication color, wherein the indication colors correspond to the plurality of color patches 20, so that the color pattern 30 is visually associated with a information of the food flavors. In an embodiment, the plurality of color patches 20 and the indication colors have substantially equivalent colors.

[0019] In different applications, the plurality of color patches 20 on the carrier 10 can be separately arranged from the colorimetric sensor array, and colors of the plurality of color patches 20 are associated with or equivalent to the indication colors of the sensing materials of the colorimetric sensor array. Alternatively, the colorimetric sensor array may be directly formed with the plurality of color patches 20 on the carrier 10. That is, the plurality of color patches 20 is the plurality of sensing materials of the colorimetric sensor array. In other words, colors of the plurality of color patches 20 are equivalent to the indication colors of the plurality of sensing materials of the colorimetric sensor array. In different applications, the plurality of color patch 20 can display the indication colors of the plurality of sensing material of the colorimetric sensor array in real-time. In one embodiment, the plurality of color patches 20 with similar colors is arranged adjacent to each other, as shown in FIG. 1. In another embodiment, the plurality of color patches 20 with distinct colors is arranged adjacent to each other, as shown in FIG. 2.

[0028] In the present invention, the colorimetric sensor array presents the color patch corresponding to the indication color according to the result of the chemical reaction, and conveys the food flavors to consumers with the color patch, not only providing the information about the food flavor in a more scientific way, and rendering a better method than written words (i.e., color combinations) for consumers to understand. In other words, the present invention presents the food flavors in a visual manner to be a medium for conveying the information of the food flavors. For vendors who sell fresh food products which are normally without standard, meaning those fresh food products are inconsistency on quality or nature. By using the colorimetric sensor array of the present invention, the fresh food products to be advertised or sold can be classified in the first place so as to facilitate sales, and consumers are easy to select and purchase based on their own needs.
