However, there are also contributions by several other authors, as well, including Eeke van der Burg, John Gower, Pieter Punter, Els van den Broek, and Margo Flipsen. This book discusses the use of Multivariate Data Analysis to solve problems in sensory and consumer research. More specifically the focus is on the analysis of the reactions to certain characteristics of food products, which are in the form of scores given to attributes perceived in the food stimuli; the Publications in food science and nutrition.FoodSensory evaluationMultivariate analysisFoodSensory evaluation.Multivariate analysis.664664.07664.072Dijksterhuis Garmt B146972MiAaPQMiAaPQMiAaPQBOOK996197287803316Multivariate data analysis in sensory and consumer science517027UNISA
