Abstract

Apricot is an important fruit species in Hungary both for fresh consumption and processing. Physical parameters and change of nutrients of nine apricot cultivars were studied during the ripening period. Four Hungarian and five North-American apricot cultivars were chosen for investigation. Changes in the physical parameters were measured by three different methods (Magness-Taylor hand penetrometer, Bookfield CT3 Texture Analyser with TA 44 and TA 9 measuring head). Significant differences in flesh firmness among the cultivars were observed mainly at the beginning of ripening time. Adhesiveness, cohesiveness and chewiness of the fruits decreased continuously during ripening. The studied cultivars showed significant differences in these traits. Sugar and acid contents were also measured during ripening. The cultivars showed small differences in sugar content and bigger differences in acid content of the fruits. Our data measured and collected during this study can be useful in characterizing the apricot cultivars studied. Changes in the texture parameters responsible for transportability and the technological usability of the fruits were described across the whole ripening period. Our results may help growers as well as food technologists to determine the optimum harvest date of cultivars intended to be used for different purposes.
