A Disposable Sensor For Assessing Artocarpus heterophyllus L. (Jackfruit) Maturity

Abstract : The purpose of this work was an attempt to monitor the ripeness process and to investigate the different maturity stages of jackfruit by chemometric treatment of the data obtained from the disposable sensor. Response of the sensor strip fabricated using screen-printing technology was analyzed using Principal Component Analysis (PCA) and the classification model constructed by means of Canonical Discriminant Analysis (CDA) enable unknown maturity stages of jackfruit to be identified. Results generated from the combination of the two classification principles show the capability and the performance of the sensor strip towards jackfruit analysis.

However there is no precise measurement, clear definition or standard unit to identify product quality objectively since quality is always associated with the degree of acceptance by the consumers. Qualitative evaluation of agricultural products has been of interest to many and what we call
