Supercritical fluid impregnation (SFI), an eco-friendly technique, was applied to incorporate phenolic compounds from passion fruit bagasse into corn starch bioaerogel. This work investigated the effect of depressurization rate, contact time, and the number of cycles of SFI on the functionalization of the bioaerogel. SFI was conducted in static operation mode at 65 degrees C and 37.5 MPa, evaluating the effect of depressurization rate (slow and fast), process time (0.5-10 h), and number of cycles in terms of total reducing capacity (TRC), antioxidant capacity (Oxygen Radical Absorbance Capacity - ORAC and Ferric Reducing Antioxidant Power - FRAP), and piceatannol content of the impregnated bioaerogel. In single-cycle SFI the best results for TRC (0.65 +/- 0.01 mg GAE/g aerogel), FRAP (1.61 +/- 0.02 mg TE/g aerogel), and ORAC (3.42 +/- 0.01 mg TE/g aerogel) were obtained with a fast depressurization rate and a contact time of 10 h. These results were surpassed when investigating the number of SFI cycles, with an increase of approximately 200 % in ORAC, 105 % in FRAP, and 330 % in the piceatannol content for SFI carried out with six 0.5 h cycles. The functionalization of corn starch bioaerogel with phenolic compounds from passion fruit waste by SFI offers a green engineering approach to obtain a high-value product with potential application in the pharmaceutical, nutraceutical, and food industries.
