Equilibrium and fixed-bed kinetics study on hazelnut skin polyphenols extraction using choline chloride –lactic acid-based NADES and water as solvents

Extraction of phenolic compounds from lucuma (Pouteria lucuma) seeds with natural deep eutectic solvents: modelling using response surface methodology and artificial neural networks

“…Additionally, NADES has the capability to establish hydrogen bonds with phenolic compounds, which enhances their solubility (Dai et al, 2013a,b). Given the nature of polyphenols, which are considered hydrogen bond donors (HBD) (Bakirtzi et al, 2016), their interaction with acetate anions could generate strong bonds, resulting in a more stable supramolecular structure during the process of extraction, increasing the efficiency of the process (Bakirtzi et al, 2016;Mazzeo et al, 2023).…”

“…These studies have demonstrated the capacity of these solvents to efficiently extract bioactive compounds, such as flavonoids, phenolic acids, anthocyanins, and alkaloids, from various plant-derived materials, mainly from residues of the agrifood industry, such as peels, hulls, seeds, pomace, and leaves. The extraction ability of this solvent has been investigated, among others, in date seed (Airouyuwa et al, 2023), olive leave (Alrugaibah et al, 2023), cocoa bean shell (Rebollo-Hernanz et al, 2021;Benítez-Correa et al, 2023), pomegranate peels, almond hulls, and elderberry pomace (Bertolo et al, 2023), buckthorn leaves (Cui et al, 2018), hazelnut skin (Mazzeo et al, 2023), mango by-products (Pal and Jadeja, 2020;Ojeda et al, 2023), sour cherry pomace (Popovic et al, 2022) and avocado peels (Posta et al, 2023).…”
