Abstract
Gas sensing technology is a subject that is increasingly being studied and becoming more applicable in areas such as fermentation, personal safety, academic research and many others. This study includes different types of sensors. This research focused on gas sensors, specifically volatile organic compounds sensors. Volatile organic compounds are applicable in many production areas such as alcoholic beverage production. Beer is the most produced alcoholic beverage worldwide and the three main volatile organic compounds applicable to the production of beer are Ethanol, Methanol, and Hydrogen sulphide which contribute majorly to the mouth feel, flavour and the odour of beer. During beer fermentation, these three compounds require constant monitoring to avoid being over produced and contamination. Currently, the detection of Ethanol, Methanol, and H2S are undertaken by conventional methods such as high-liquid-performance chromatography, gas chromatography, and near-infrared spectroscopy. These methods are time-consuming. They lack portability and are very expensive...
