Dataset of "GREEN ENZYMATIC-ASSISTED EXTRACTION OF BIOACTIVE COMPOUNDS FROM MEDITERRANEAN FRUITS AND VEGETABLES BY-PRODUCTS"

This data article describes a dataset obtained from the aqueous enzyme-assisted extraction (EAE) of bioactive compounds from lemon peel, pomegranate peel, broccoli leaves, and grated tomato by-products. The dataset includes the experimental conditions used for each extraction assay: i) type of by-product, ii) type of enzyme (Pectinex® Ultra Pulp, Pectinex® Yieldmash Plus Celluclast®, and Viscozyme®), iii) enzyme concentration (0, 1, and 2%), iv) incubation time (0, 30, 60, 90, and 120 min), and v) extract fraction (supernatant or pellet). The analytical data includes antioxidant capacity, total phenolic content, flavonoids, punicalagins, glucosinolates, isothiocyanates, and carotenoids, depending on the composition of each plant matrix. All studied by-products showed compounds of interest and can be considered suitable raw materials for the recovery of natural bioactive compounds. Pomegranate peel showed high antioxidants and phenolic values, mainly related to punicalagins. Lemon peel contained phenolic and flavonoid compounds, broccoli leaves provided antioxidants and glucosinolate-related compounds, and grated tomato by-products showed relevant carotenoid content, especially lycopene-related compounds. Although differences were observed between EAE samples and control, the tested enzyme concentrations, 1 and 2%, and incubation times, 30–120 min, did not show a clear dose-response or time-response trend. Therefore, the dataset also provides useful information about experimental conditions with limited discriminatory capacity. The complete dataset is supplied with this data article and will be deposited in Zenodo. These datasets may help researchers to design more precise extraction assays using lower enzyme concentrations and shorter incubation times for the revalorization of agri-food by-products.
