Impact of Arginine and Ultrasound Pre-Treatments on Anthocyanin, Phenolic Content, and Color Properties of Strawberries
Abstract
This study aimed to evaluate the effects of arginine and ultrasound treatments on the quality attributes of strawberry (Fragaria × ananassa Duch. cv. ‘Albion’). Fruits were divided into five groups: control (C), water treatment (W), arginine (Arg), water+ultrasound (W+UltS), and arginine + ultrasound (Arg+UltS). All samples were stored at 5 ± 2 °C and 85–90% relative humidity for 20 days, and quality analyses were performed at 4-day intervals. The parameters measured included total monomeric anthocyanin content (TMAC), total phenolic content (TPC), color values (L*, a*, b*, hue), weight loss, fruit firmness, soluble solids content (SSC), titratable acidity (TA), and the SSC/TA ratio. Results showed a decline in TMAC and TPC across all treatments during storage, with the most pronounced reductions in the Arg+UltS group. While no significant differences were observed among treatments for L*, a*, and b* values, the hue angle was significantly reduced in the Arg+UltS treatment compared with the control, suggesting treatment-induced modifications in fruit pigments. W and W+UltS treatments were the most effective in preserving fruit firmness, maintaining SSC, and the reducing weight loss. Overall, these findings highlight the importance of selecting appropriate pre-storage treatments to minimize quality losses in strawberries during cold storage. Future studies should explore different arginine concentrations and ultrasound parameters to achieve more optimized outcomes.
