Short summary
An optimized extraction process yielded grape pomace extract (GPE) with high phenolic (163.99 mg GAE/L) and anthocyanin (136.46 mg C3GE/L) content and 69.21% antioxidant activity, which was then used to create a smart film (GPE-BS) that changes color at extreme pH and maintains structural integrity for 2 hours as a straw.

Key points
- Optimized grape pomace extraction yielded GPE with 163.99 mg GAE/L phenolics, 136.46 mg C3GE/L anthocyanins, and 69.21% antioxidant activity.
- GPE incorporated into babassu mesocarp starch films (GPE-BS) created a smart film changing color at pH 2 and 13.
- GPE-BS films showed enhanced hydrophobicity, antioxidant activity, and elongation at break compared to control films.
- The GPE-BS film maintained structural integrity for 2 hours when used as a straw for sugar-free cola.

Abstract
Abstract Grape pomace (GP) is a byproduct rich in bioactive compounds. This study optimized the extraction of these compounds using a Central Composite Rotational Design (CCRD 22), evaluating temperature (41–69 °C) and time (0.8–3.2 h). The optimized extract (GPE) showed high phenolic content (163.99 mg GAE/L), anthocyanins (136.46 mg C3GE/L), and antioxidant activity (69.21% DPPH). GPE was incorporated into babassu mesocarp starch (BS) films, producing an active smart film (GPE-BS) that changed color at extreme pH (2 and 13). The GPE-BS film also showed improved hydrophobicity, antioxidant activity, and elongation at break compared to BS films (control). When tested as a straw for sugar-free cola, the film maintained structural integrity for 2 h. Thus, GPE-BS films are promising for smart food packaging or as edible straws.
