An analysis of the postharvest behavior of four genetic materials of feijoa (Acca sellowiana Berg)

ABSTRACT The characteristics of four genetic materials feijoa (GM7, GM12, GM26, and GM27) after 7, 15, 30 days refrigerated storage (5°C 97% RH) followed by 7 shelf-life (20°C 80% were analyzed. Respiratory activity, weight loss, flesh firmness, external internal color, browning, total polyphenol content (TPC), antioxidant capacity (TAC) determined. GM12 exhibited the best respiratory activity in most evaluated moments. Significant i.e., 5%–7% initial at 7+7 15+7 8%–10% 30+7 was observed, especially GM26. At harvest, firmness 38–57 N reduced 50%–65% shelf-life. color did not show noticeable differences. Internal which increased with progress, less GM7, possibly owing to its lower TPC TAC. GM26 GM27 least firm had maximum loss. Although GM7 a functional compounds, it browning. presented significant high acceptable retention making promising material analyzed this study.
