ResearchLine

Description: Recovery of bioactive compounds from winemaking waste with natural deep eutectic solvents. The main by-product of winemaking is pomace which is composed of seeds, pulp, skin and stems and is rich in bioactive compounds such as polyphenols. Natural deep eutectic solvents (NADES) are an effective, safer, non- flammable and more environmentally friendly alternative to conventional organic solvents. A systematic study of the extractive capacity of different NADES for different families of polyphenols present in the pomace is proposed. Firstly, different NADES will be prepared and characterized. Next, the extraction efficiency will be determined for each compound or family of bioactive compounds. The variables of the extraction process will be optimized through experimental design and response surface methodology. Theoretical computational studies will be carried out using COSMO-RS to choose the NADES that theoretically has the greatest solubilizing capacity, and to validate the experimental results. Finally, the antioxidant activity of the NADES extracts and their applicability in the food, cosmetic and pharmaceutical industries will be evaluated.

Description: The research initiative, focused on extracting bioactive compounds from winemaking waste using natural deep eutectic solvents, aligns strongly with sustainability principles, as outlined in the MSCA Green Charter. This charter underscores the importance of minimizing environmental impact and promoting eco-friendly practices in research. Integrating Artificial Intelligence (AI) represents a significant opportunity. By employing in silico methods such as COSMO-RS to select an optimized NADES composition, the research can pinpoint the most effective conditions for extracting bioactive compounds from the waste, thereby contributing to a more sustainable approach. Furthermore, this project embodies the principles of a circular economy. By repurposing winemaking waste, particularly pomace, which is rich in bioactive compounds, the initiative effectively reduces environmental burdens associated with waste disposal. This practice aligns with broader sustainability objectives and reduces the overall ecological footprint of the winemaking industry. Collaboration with industry stakeholders is essential. Engaging wineries and other relevant sectors, such as the food, cosmetic, and pharmaceutical industries, facilitates the practical application of research findings. This collaboration not only validates the research but also accelerates the adoption of sustainable practices in these sectors. Communicating the benefits of sustainable winemaking practices, including the efficient utilization of waste for valuable compounds, serves to garner public support and potentially influence consumer behaviour towards more eco-conscious choices. Also, regarding to the implications of the project on society, it may lead to job creation in waste management and extraction industries.
