Electronic noses and tongues in food science Electronic Nose and Tongue in Food Science describes the electronic products of advanced chemical and physical sciences combined with intuitive integration of microprocessors advanced bioinformatics and statistics. These include for example voltammetric bio electronic piezoelectric platforms made from a variety of components including nanoparticles enzyme biosensors heavy metals graphite epoxy composites metal oxide semiconductors microelectrodes microfluidic channels pre manufactured gas sensors redox enzymes and others and is an ideal resource for understanding and utilizing their power in Food Science settings. Devices used to analyse one particular food item can theoretically be adapted for other food items or components. This does not just mean the re deploying the physical platforms but also the mode of bioinformatic and statistical analysis. This includes artificial neural networks (ANN) linear discriminant analysis (LDA) partial least squares (PLS) principal component analysis (PCA) etc. In other words there is cross transference of chemistry physics concepts techniques findings and approaches from one food to another. Electronic noses and tongues are two of these devices but are advancing in application and importance. This book provides examples of the use of electronic noses and tongues to characterise components that contribute to sensory or compositional profiles from ripening to harvesting and from storage of raw materials to packaging and consumption. These devises are suitable for high throughput analysis quality control or to determine the nature and extent of spoilage and adulteration and have also been used to ascertain the geographical origins of food and mixtures
