Abstract: The aqueous (AF) and solid (SF) fractions obtained as co-products in the aqueous extraction of pecan nut oil assisted by Alcalase were evaluated. In the AF, the degree of protein hydrolysis (DH) and the electrophoretic profile of protein hydrolysates, phenolic compounds, and antioxidant capacity (reducing potential of the hydrophilic compounds, RPHC, 2,2-diphenyl-1-picrylhydrazyl, DPPH; and inhibition of lipid peroxidation) were determined. The proximate composition and microstructure were evaluated in SF.

A three-component simplex-centroid mixture design coupled with response surface methodology (RSM) was applied to generate statistical models and to analyze the dataset. The method was also applied to evaluate the effect of different solvents (ethanol, water, and acetic acid) on the extraction of bioactive compounds of pecan nut cake (PNC) and its antioxidant activity.

Therefore, the effects of time and extraction temperature on the bioactive compounds and antioxidant activity of Hibiscus sabdariffa calyx were evaluated. In addition, the effects of copigmentation and pH on the stability of anthocyanins were assessed and the cytotoxic effects (LC, IC, and GC) of the extracts were determined in relation to tumor cell lines - Caco-2, HepG-2, HCT8, and A549.

Sabará), to optimize the solvent proportion (water, ethyl alcohol, and propanone), and to characterize the extract according to the chemical composition, antioxidant, and antimicrobial properties. Proximal composition, total phenolic content (TPC), antioxidant, and antimicrobial activities were analyzed.
