“…Considering the high flavonoid contents in these byproducts, we can assert that they could be used in the pharmaceutical, food, and cosmetic industries (Carullo, et al, 2018). According to different reports, orange and mango peels have a flavonoids content of 3.22 ± 0.06 and 6.83 ± 0.09 mg of quercetin per gram of dry sample, respectively (Ghosh, et al, 2019). These data are higher compared to the results found in the present study (0.43 ± 0.02 mg QE/g S db for orange peel and 1.48 ± 0.03 mg QE/g S db for mango peel), which may be related to the fact that the cited authors used pure ethanol to carry out two extractions during four hours, which could influence the concentration of flavonoids obtained in the extracts.…”

Currently, the use of agro-industrial waste represents a viable alternative for obtaining valuable compounds that, in the case of biorefineries, is an opportunity for improvement. In this context, the aim of our study was to determine the flavonoid content and the antioxidant capacity of 30 byproducts from fruit processing in Colombia and propose possible applications. We analyzed the antioxidant capacity of the ethanolic extracts from each byproduct using the ferric reducing antioxidant power (FRAP) and the reducing power of antioxidant activity (RPAA) assays, as well as the oxygen radical absorbance capacity (ORAC) test. We found that tree tomato peels and stem and peach peels had a high flavonoid content, with values greater than 8,271.82 ± 702.70 μg quercetin per gram of dry sample. We also found that mango (22,676.57 ± 759.71 μg TE1/g Sdb, 3,692.38 ± 92.67 μg GAE/g Sdb), soursop (22,117.13 ± 754.94 μg TE1/g Sdb, 4,858.79 ± 156.71 μg GAE/g Sdb, 14,713.39 ± 757.95 μg TE2/g Sdb), grape (17,027.85 ± 765.11 μg TE1/g Sdb, 13,395.15 ± 659.31 μg TE2/g Sdb), peach peels (17,910.21 ± 1,424.33 μg TE2/g Sdb) and seeds (4,316.46 ± 112.00 μg GAE/g Sdb, 20,093.32 ± 1,317.93 μg TE2/g Sdb), and grape stalk (3,552.26 ± 31.63 μg GAE/g Sdb) showed a high antioxidant capacity in the different tests performed. Our results demonstrate that fruit byproducts have potential use in the pharmaceutical, ood, and cosmetic industry due to heir flavonoids content and their high antioxidant capacity.
