The application of principal component analysis to characterize a consumer structure of apple quality


In the paper, the preferences were presented of consumers in a city of Lublin regarding properties impacting the quality of apples. A ‘PCA’ method (Principal Component Analysis) was used to describe the preferences studied. It was found that those preferences mainly referred to two groups of properties connected with the external appearance of the fruit and the method of storing them; moreover, they also covered the characteristics of cultivars, such as: taste, firmness, and juiciness of parenchyma. With this Analysis applied, it was also possible to identify differences in the preferences of women and men. It was found that the size of apples and their cultivar only insignificantly differentiated the preferences of women and men.
