摘要
This paper presents an approach of artificial neural networks to predict the sensorial qualities of wines. A Kohonen network has been used as a software tool in order to increase the human skills in this kind of application. An initial prototype was implemented using the artificial neural networks technology, together with the Visual Basic software from Microsoft, for evaluation of sensorial qualities of seven samples of Barbados cherry (Malpighia glabra L.) wine. Fifty consumers chosen, perhaps, had been used to obtain the sensorial data using a hedonic scale of 1-9 times. Sensorial values of flavor, aroma and appearance obtained of the hedonic dating were compared. The characteristics of wine, such as flavor and color, were similar to the Barbados cherry fresh fruit. The consumers evaluated the wines as very good; all sensorial qualities were more than 5 in hedonic scale. Results showed that Kohonen network classified the Barbados cherry wines in a distinct group, for frequency among their sensorial responses. Kohonen network results were similar or better than statistical classification; this shows that the use of Kohonen algorithm in the sensorial analysis of wines is valid. Kohonenalgorithm is very good in clustering of Barbados cherry wine samples, and its uses in sensorial analyses of wines is promising.
