* Mean values for triplicates \(\pm\) SD. The values with different superscript letters are significantly different (\(p<\) 0.05). Abbreviations: AA—L-ascorbic acid (mg/100 mL); DHAA-L-dehydroascorbic acid (mg/100 mL); TAA—total vitamin C (mg/100 mL); TPC—Total phenolic content (mg GAE/100 mL); GAE: gallic acid equivalent; Antioxidant capacity—DPPH (\(\mu\)M Tolrox/mL); DPPH—2,2-diphenyl-1-picrylhydrazyl radical scavenging activity.

Table 6: L-ascorbic acid, L-Dehydroascorbic acid, total vitamin C, total phenolic content, and antioxidant capacity of the tested fruit juices. pressed apple juices. According to [PERSON] et al. [50], the explanation for the missing correlation between the AA content in apples and apple juice was closely related to AA stability, the content of other polyphenols, pH, pressing efficiency, and juice production conditions. The mixed juices with a higher quantity of rose juice (AB5, AC5) presented higher AA content than the other mixed juices, as expected. In mixed juices, AA reductions of 56.6%, 58.4%, 60.6%, 59.7%, and 58.7% were found for rose-strawberry juices formulations AB1, AB2, AB3, AB4, and AB5, respectively.
