During the term of two years this study attempts to consider consumers preferences within existing quality management systems in retail. The aim was to develop a quality index which involves sensory characteristics. Therefore, about 4000 fruits of the cultivars ‘Fuji, Yataka’, ‘Elstar, Elshof’, ‘Golden Delicious, Reinders’ and ‘Jonagold, Rubinstar’ were analyzed in three steps in the first experimental period (about 1000 fruits per cultivar). In the first place different fruit characteristics such as flesh firmness and chlorophyll content were measured non-destructive. Next the fruits were tested sensorial by consumers at four retail trade locations in Osnabrück. For the assessment of the taste an eight part of an apple was used. The remaining seven eight parts were required for destructive investigations. Coefficients of linear correlation between results of non-destructive respectively destructive analysis on the one side and sensorial determined results on the other side were calculated. Unexpectedly, the correlations between these different parameters were small. Therefore, more data will be collected in a second experimental period to develop the quality index.
