Description
Interest in sustainable food production and consumption has been growing, with soybean (Glycine max L) being highlighted as a nutritious and low-cost option used in food products and dietary supplements. The extraction of compounds from soybeans using green solvents is relevant for its safe and environmentally friendly properties. Among these, the Natural Deep Eutectic Eutectic Solvents (NADES) are renewable mixtures that, in specific proportions, generate liquids with lower melting points than their individual components. This study aims to select the best method to extract polyphenols from soybean using a combination of hydrophilic and hydrophobic NADES. The COSMO-RS model was used to predict solubility and sequential extractions were carried out with different combinations of NADES. Two extraction methods were compared: heating with stirring (HS) and heating with orbital shaker (HOS), at 45 °C for 45 min. Results showed that the combination of C:T and CA:Glu was the most effective, with a higher total polyphenol content (TPC) in HS (23.6 mg GAE/g) compared to HOS (17.1 mg GAE/g). Sequential extraction proved to be effective and the use of COSMO-RS facilitated the identification of optimal NADES combinations.
