For this purpose, samples were collected from each step of
juice processing and these were subjected to spectrophotomeric,
HPLC-based, and LC–QTOF–MS-based quantitative and qualitative
analyses in order to monitor the changes in total antioxidant levels,
as well as in individual phenolics. Moreover, we applied an in vitro
simulated gastrointestinal digestion model to determine the effect
of industrial-scale juice processing on the bioavailability of black
mulberry antioxidants.
