Biosensors for fruit andvegetable processing

WithDanielle Cristhina Melo Ferreira, Lucilene Dornelles Mello, Renata Kelly Mendes, Lauro Tatsuo Kubota

The increase in consumption of high-quality products associated with the demands from society for more environmentally friendly production practices results in the necessity of continuous improvement of beforeand post-harvest quality detection methods. Current analytical practices

in the food industry are time consuming and require skilled labor. These analytical techniques require time-consuming separation, expensive instrumentation, and the use of chemicals with high purity. Most of these drawbacks can be overcome by applying enzymatic analysis (Newman et al., 1998; Prodromidis and Karayannis et al., 2002). In this sense, biosensors have been used for many years to provide process control data in food processing due to the characteristics of the produced devices to be of small size, accurate, and economically viable emerging technology for rapid diagnostics sector applied to agricultural products (Hall, 2002).
