Abstract The use of edible coating has been an alternative to maintain the quality of vegetables and prolong their post-harvest life. This study aims to evaluate bioactive compounds in Spondias tuberosa submitted to different coating formulations based on Chlorella sp. associated with the pomegranate seed oil, to establish the one that best maintains post-harvest quality. The experiment was set in a completely randomized design, in a 5 × 6 factorial scheme, represented by five coating techniques (T1 = control; T2 = 0.5% Chlorella sp.; T3 = 1% Chlorella sp.; T4 = 1.5% Chlorella sp.; T5 = 2% Chlorella sp.), using 0.3% of pomegranate seed oil in coatings, during five evaluation periods (0, 1, 2, 3, 4 and 5 days), stored in BOD incubator at 24 ± 2 °C and 85 ± 5% RH, with three replicates of ten fruits per plot. Chlorella sp. associated with pomegranate seed oil produced a modified atmosphere around the fruit, retarding the ripening process. Coatings preserved the content of ascorbic acid and phenolic compounds. The treatment containing 2.0% of Chlorella sp. associated with pomegranate seed oil provided the best maintenance for fruit quality.
