Towards understanding red drupelet reversion in blackberry fruits through high hydrostatic pressure Academic Article in Scopus uri icon

abstract

  • Red drupelet reversion (RDR) is a postharvest issue that decreases blackberry quality. The main objective of the present work was to evaluate high hydrostatic pressure (HHP) as a method to induce RDR in blackberry fruit and to analyze the association of anthocyanin content, pH, and acidity with RDR presence. Blackberry fruits were pressurized to 200 MPa during different times and stored for 2 days. After HHP treatment (3, 5, and 10 min and 1 day of storage), 100% of blackberry drupelets exhibited red coloration, indicating that HHP could be used as a method to induce homogeneous RDR. Interestingly, anthocyanin content, pH, and acidity concentration were not associated with the presence of RDR. However, more studies are needed to evaluate the participation of these variables in RDR. © 2025 The Author(s). Published with license by Taylor & Francis Group, LLC.
