Resumen
The environmental impact caused by the generation of agro-industrial residues from citrus fruits has generated an increase in research to propose the uses that can be given to the peels and/or bagasse, which have high contents of phenolic compounds and terpenes. These compounds are associated with a wide variety of biological properties such as antimicrobial activity, antioxidant, anti-inflammatory, antimutagenic activity, among others. The objective of this work was to carry out an experimental approach, which allowed establishing the relationship between the degree of maturity of the fruit (peel) of mandarin (Citrus reticulata) and the content of phenolic compounds and total flavonoids, by means of ultrasound-assisted solvent extraction. To determine the presence of these compounds, colorimetric assays and determination of total polyphenols by the Folin Ciocalteu assay and flavonoids by the AlCl3 assay were performed. The effect of the solvent and proportional mixtures of water/ethanol were also evaluated. The highest content of polyphenols was 50.0 mg AG/g extract, in the samples in a state of pintona maturity, with a mixing ratio of 70/30 ethanol/water. Regarding total flavonoids, a concentration of 9.7 mg quercetin/g extract was obtained, present in green peels and with a mixing ratio of 70/30 ethanol/water. Additionally, a scientometric analysis was developed, using specialized databases and the text mining program (Vantagepoint, academic version 12.0) to identify value-added products and the economic potential that can be generated from the use of citrus agro-industrial residues.
