3.1.2. Free Sugars

Regarding free sugars (Table 1), fructose and glucose (4.021 ± 0.006 and 3.86 ± 0.05 g/100 g fw, respectively) were the most abundant ones, but lower concentrations of sucrose and an unknown sugar were also found. The total amount detected in this study (7.91 ± 0.06 g/100 g fw) was very similar to the one reported by Palíková et al. (7.2 g/100 g fw), with fructose (3.2 g/100 g fw) and glucose (2.9 g/100 g fw) as free sugars detected [19]. These latest were also found in other studies, in concentrations of 2.80 and 2.90 g/100 g fw (fructose), and 3.64 and 3.2 g/100 g fw (glucose) [19,23]. As for Wojtek cultivar studied herein, sucrose was also previously detected by Oszmia ´nski et al. (0.04 g/100 g fw) in the same cultivar [23].
