2.4. Juice packaging and storage
PEF-processed pomegranate juices were collected inside a sanitary
laminar hood using connection tubing from PEF outlet to the hood
where juices (200 mL) were packaged into regular PET bottles or
antimicrobial-coated PET bottles. Untreated juices were packaged in
the same way and used as controls. All juice samples were stored at 4 °C.
