Drying is an effective method for preserving the quality attributes of agricultural products over extended periods. In this study, mandarin slices were dried using the shade-drying method, either without pretreatment (control) or with pretreatments, including ascorbic acid, gum arabic, and citric acid. The shortest drying time was observed in the gum arabic-treated samples, lasting 120 minutes. In all samples, the drying rate was initially high but decreased as moisture content declined. Color analysis revealed that the yellowness (b) value, an important quality attribute for mandarins, was closest to that of fresh fruit in the gum arabic-treated samples. The highest pH value was recorded in the control group (3.60), while the lowest values were observed in the ascorbic acid (2.92) and gum arabic (2.97) treatments. The °Brix value was highest in the ascorbic acid-treated samples (0.9) and lowest in the citric acid-treated samples (0.4), indicating that the pretreatments significantly influenced the quality parameters. The highest rehydration ratio was obtained in the gum arabic-treated samples (3.96). Sensory evaluation showed that overall acceptability was highest for the control and ascorbic acid-treated samples, whereas gum arabic treatment resulted in lower acceptability. These findings provide insights for optimizing pretreatment selection in dried mandarin production and can guide future studies evaluating different drying techniques and their combinations.
