Changes in fruit antioxidant activity among blueberry cultivars during cold-temperature storage.

摘要: Antioxidant activity, total phenolic content, anthocyanin and six other fruit characters including titratable acid concentration, soluble solids, firmness, percentage of bruised berries were determined for nine blueberry (Vaccinium L. sp.) cultivars at harvest various postharvest intervals after storage 5 °C. Berries from MSU-58, Brigitta, Legacy stored successfully 7 weeks, Bluegold 3−5 Bluecrop, Elliott, Nelson 3 Jersey Little Giant fewer than weeks. During the time they retained marketable quality, one cultivar (MSU-58) demonstrated a 29% increase in antioxidant activity. None showed significant decrease activity value during storage. content strongly correlated with each (r = 0.87−0.99, P < 0.01). All three parameters moderately solids 0.47, ≤ 0.05; r 0.4...
