### Folate  
The folate content of all three cultivars during storage is shown in Table 6. The folate content of the Arianna, Francesca, and Silvia WF at time 0 was 126 \(\upmu\)g/kg FW, 171.55 \(\upmu\)g/kg FW, and 113.72 \(\upmu\)g/kg FW, respectively. The oven-drying process slightly decreased the folate content of the fruits of all cultivars, with the folate content being 120.96 \(\upmu\)g/kg FW, 115.19 \(\upmu\)g/kg FW, and 103.09 \(\upmu\)g/kg FW in the DF at time 0, respectively. The folate content of the WF during storage at \(-20\)\({}^{\circ}\)C had an increasing trend from 1M until the end of storage for all cultivars, and, at the end of storage, the folate contents of the Arianna, Francesca, and Silvia WF were detected to be 190.61 \(\upmu\)g/kg FW, 208.4 \(\upmu\)g/kg FW, and 132.06 \(\upmu\)g/kg FW, respectively. In the DF, similarly to the WF, the folate content increased with the extension of storage for all cultivars. \begin{table}

Table 6: Average of folate content (\(\upmu\)g/kg FW) in cultivars of Arianna, Francesca, and Silvia fruits. The data are expressed as mean \(\pm\) standard error. Different lowercase letters indicate significant differences for \(p\leq\) 0.05 in each cultivar during storage. Different uppercase letters indicate significant differences for \(p\leq\) 0.05 for all cultivars for a specific storage time. WF: whole fruits, DF: dried fruits. 0 M: 0 months of storage; 1 M: 1 month of storage; 3 M: 3 months of storage; 5 M: 5 months of storage; 7 M: 7 months of storage. At \(-80\)\({}^{\circ}\)C storage, the folate content of the WF for all cultivars increased until the end of storage, as registered for the \(-20\)\({}^{\circ}\)C storage.
