Four rice samples of long grain type were tested using an electronic nose (Cyranose-320).Samples of 5 g of each variety ofrice were placed individually in vials and were analyzed with the electronic nose unit consisting of 32 polymer sensors.TheCyranose-320 was able to differentiate between varieties of rice.The chemical composition of the rice odors for differentiatingrice samples needs to be investigated.The optimum parameter settings should be considered during the Cyranose-320 trainingprocess especially for multiple samples,which are helpful for obtaining an accurate training model to improve identificationcapability.Further,it is necessary to investigate the E-nose sensor selection for obtaining better classification accuracy.A re-duced number of sensors could potentially shorten the data processing time,and could be used to establish an application pro-cedure and reduce the cost for a specific electronic nose.Further research is needed for developing analytical procedures thatadapt the Cyranose-320 as a tool for testing rice quality.
Four rice samples of long grain type were tested using an electronic nose (Cyranose-320). Samples of 5 g of each variety of straw were placed individually in vials and were analyzed with the electronic nose unit consisting of 32 polymer sensors. Cyanose-320 was able to differentiate between varieties of rice. The chemical composition of the rice odors for differentiating rice samples needs to be investigated. The optimum parameter settings should be considered during the Cyranose-320 trainingprocess especially for multiple samples, which are helpful for obtaining an accurate training model to improve identificationcapability.Further, it is necessary to investigate the E-nose sensor selection forPARRable classification accuracy. A re-duced number of sensors could potentially shorten the data processing time, and be able to establish an application pro-cedure and reduce the cost for a specific electronic nose. Future research is needed for developing analytical procedures thatada pt the Cyranose-320 as a tool for testing rice quality.
