Pungency in chillies has been rewarded great response due to its close relationship with health and safety of human being and different methods of quality evaluation have engrossed much curiosity in researchers. In this report, an low-cost and extremely sensitive sensor array for the identification and estimation of pungency in green chillies has been designed. The pungency assessment MOS array was based on a metal-oxide semiconductor device (MOS) and a comparison with chemical evaluation results. The designed MOS sensor array is tested by classifying the pungency in different types of green chillies. Experimental results confirm the efficiency of the proposed methods (chemical and MOS method).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
