All the preservation treatments studied, whether PA or HHP, caused structural modifications in red Lamuyo-type sweet pepper tissues, but HHP T4 and PAwere the treatments that had the least impact on the microstructure.These same treatments (HHP T4 and PA) were also the ones that least affected the bioactive compound content and the texture.
High-pressure treatment at 500 MPa could provide an alternative to pasteurization, the traditional thermal treatment for sweet pepper preservation, as the texture properties and bioactive compound content (fibre, carotenoids and antioxidant activity) of the red pepper tissues were found to be similar. Owing to their high bioactive compound
