Abstract
Texture measurements with a Kramer shear press carried out on canned plum halves of two Swiss cultivars at three different ripeness stages, showed a significant increase in the firmness of all samples when 500 ppm Ca(II)-ions were added to the 30% sucrose syrup can liquid. In sensory tests, firmer plums were generally preferred over softer fruits. Sensory intensity ratings of colour of canned plum halves were in good agreement with the total anthocyanin content as determined spectrophotometrically. Hedonic colour rating increased with increasing colour intensity. If artificial colouring is to be avoided, ripe fruit of anthocyanin rich plum cultivars should be used for canning
