Development of a green ultrasound-assisted procedure for the extraction of phenolic compounds from avocado peel with deep eutectic solvents

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

“…The TPC value obtained was 3,601.51 ± 0.51 mg GAE/100 g LSF, DW. Our results show that the TPC value was higher than other agroindustrial waste such as mango peel (2,305.0 mg GAE/100 g, DW) (Ojeda et al, 2023), cocoa pod (1,500 mg GAE/100 g, DW) (Benítez-Correa et al, 2023) and cherry pomace (323.83 mg GAE/100 g, DW) (Popovic et al, 2022), but lower than avocado peel (8,290 mg GAE/100 g, DW) (Posta et al, 2023) and mango seed (6,001.0 mg GAE/100 g, DW) (Ojeda et al, 2023), where different deep eutectic solvents were used.…”

“…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).…”
