Abstract
Feijoa is a new fruit crop in Mexico established in the tropical highlands.
Total phenols and antioxidant capacity were determined for feijoa fruit in postharvest at 4 and 25°C for 24 d, and at 10°C for 44 d.
The total phenolic content in pulp extracts was between 71 and 260 mg GAE 100 g‑1 FW. Antioxidant activity in the extracts of the feijoa pulp was 2.93 μm eq.
Trolox g‑1 FW at harvest.
Extracts of the pulp of fruit stored at 4°C for 24 d had higher bioactive compounds than extracts of pulp of feijoa fruit stored at 25°C for 24 d.
At 10°C, the total phenols and total flavonoids did not decrease significantly over 39 d.
In the flower stamens, total phenols were 134.4 mg GAE g‑1 DW, and in the petals 19.0 mg GAE 100 g‑1 DW. The feijoa fruit and flower are an option to increase the human local consumption of bioactive compounds in tropical highlands.
