Structure and nanostructure of the outer tangential epidermal cell wall in vaccinium corymbosum L. (Blueberry) fruits by blanching, freezing-thawing and ultrasound

The design of minimal technologies for blueberries preservation requires, among others, the knowledge of structural and ultrastructural cell changes during the processing. This work examined the main structural alterations that occurred in the outer tangential epidermal cell wall of fruits of Vaccin...
