| Abstract |
A naked-eye detective colorimetric sensor has been a major concern in the postharvest technology of agricultural products. From harvest immediately after to consumption, postharvest technology based on storage and distribution is an effective method to minimize a property loss and to sustain the high quality of safe agricultural products. Especially, colorimetric sensors 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. Monitoring the high quality of agricultural products with non-destructive methods 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, as like HITE beer label. Non-destructive sensor applications by chemical approaches will be presented. |
