Zulkafli %T Electronic tongue for fresh milk assessment: A revisit of using pH as indicator %P 167-171 %X This paper reports an investigation about using pH as an indicator of milk freshness. The objective is to develop a means to distinguish between fresh milk and spoilt milk. An electronic tongue (e-tongue) with a pH sensor has been implemented together with a graphic user interface. The definition of fresh milk was established and the e-tongue was used to measure both pasturised and non-pasturised milk in different conditions (fresh/spoilt). Based on the experimental results, we conclude that the pH parameter is not suitable as a sole indicator of milk freshness. Additional measurement using e.g. carbon dioxide sensor is required. © 2013 IEEE. %K Carbon dioxide; Sensors; Sustainable development, Carbon dioxide sensors; Fresh milks; Graphic user interface, Electronic tongues %R 10.1109/CircuitsAndSystems.2013.6671633 %D 2013 %L scholars3901 %J ICCAS 2013 - 2013 IEEE International Conference on Circuits and Systems: "Advanced Circuits and Systems for Sustainability" %O cited By 6; Conference of 2013 IEEE International Conference on Circuits and Systems: ""Advanced Circuits and Systems for Sustainability"", ICCAS 2013 ; Conference Date: 18 September 2013 Through 19 September 2013; Conference Code:102360
