Abstract A naked-eye detective chemosensor has received much attention in a variety of application field due to the simplicity, favorable performance, selectivity, and low cost. A naked-eye detective colorimetric sensor could communicate with consumers through colors which include the information of agricultural products, such as quality and ripeness. In addition, this sensor offers the time-saving convenience for the final purchasing decision as well as can be used as a marketing tool to elevate the value of product. Herein, non-destructive colorimetric sensor applications for the fruit quality determination will be presented. Monitoring the quality of agricultural products is employed by on-packaging smart sensors which are sensitive to fruit aroma and temperature. Fruit aroma sensitive colorimetric chemosensor utilizing pH dye molecules is designed for the determination of apple ripeness. A temperature-response colorimetric sensor is fabricated by thermochroic materials base on the electron transfer between acceptor and donor.
