Abstract
Blueberries are highly appreciated fruits that can be found in abundance, both as cultivars and as wild fruits in spontaneous flora, in many regions of Romania.
Blueberry cultivars may differ significantly in fruit size and mass, as well as in color.
The textural properties of blueberry fruits may also differ by cultivar and between cultivars and wild fruits.
The textural parameters of blueberry fruits, such as firmness, fracture force, and chewiness, can be assessed using puncture and compression tests.
The textural parameters may be influenced by the location of the culture (soil characteristics, temperature, and precipitation regime). This study investigates, by double compression (Textural Profile Analysis), the textural parameters of several blueberry cultivars (‘Azur’, ‘Blue Gold’, ‘Blue Jay’, ‘Blue Ribbon’, and ‘Hannah’s Choice’) and the crop location influence on these parameters as well as the possible textural differences between cultivars.
For the ‘Azur’ cultivar, the location did not influence firmness (hardness1, p=0.19) and chewiness (p=0.24) as well as springiness (p=0.47). However, for the ‘Azur’ cultivar, the fracture force was borderline and not influenced by location (p=0.054). Crop location also did not influence the firmness for the following cultivars: ‘Blue Gold’ (p=0.51), ‘Blue Jay’ (p=0.65), ‘Blue Ribbon’ (p=0.098), and ‘Hannah’s Choice’ (p=0.60). Although there were differences in fruit size between cultivars (from a minimum of 1.978 g average mass/fruit for ‘Hannah’s Choice’ to a maximum of 3.174 g average mass/fruit for ‘Blue Gold’), firmness and chewiness did not differ between cultivars; however, there were significant differences in fracture force.
