  • Effect of organic production system and harvest date on the quality of blackberry fruit for fresh and processed markets

    Creator:
    Liu, Mingyang
    Abstract:
    Blackberry (Rubus sp.) fruit are a good source of phenolic compounds and anthocyanins, and are consumed in fresh and processed forms. Though organic products become more popular, limited information is available about how different organic production methods affect the post-harvest quality of blackberry fruit. The objective of this project was...

    Siriwoharn, Thanyaporn
    Abstract:
    The influence of cultivar and maturity on polyphenolic composition and antioxidant activity was investigated by UV-Visible spectrophotometry and analytical high performance liquid chromatography (HPLC) in commercially important blackberry cultivars and selections. The anthocyanin pigments changed tremendously with ripening. Total anthocyanins increased from 74.7-317 mg/100g fw from underripe to over ripe...

  • Anthocyanin pigment, nonvolatile acid and sugar composition of blackberries

    Creator:
    Fan-Chiang, Ho-ju
    Abstract:
    The pigments of blackberry fruit were investigated by analytical and preparative high performance liquid chromatography (HPLC) to characterize anthocyanin patterns in commercially important blackberry (Rubus eubatus) cultivars and selections. Five anthocyanin pigments were detected in Evergreen blackberry and they were identified as cyanidin-3-glucoside, cyanidin-3-rutinoside, pentosecyanidin derivative and two acylated cyanidin...
