“…Overall, MAE showed higher extraction efficiency for olive pomace samples, while PLE was more efficient for winery residues. Nevertheless, UAE also provided good performance with both types of samples, and because of its simplicity, as well as the lower capital and operational costs reported [45,46], it is here proposed for further scaling up evaluation.…”

“…In this context, Talmaciu et al [45], in a comparative investment costs study considering different extraction techniques, such as MAE and UAE and supercritical fluid extraction, concluded that UAE is the one that requires lower capital and operational costs. Instead, in a study about polyphenols extraction from red wine pomace, Vega et al [46], carried out a techno-economic and life cycle assessment, and concluded that PLE not only had higher capital expenses, but also higher operational expenses and environmental concerns. Hence, considering extraction performance and simplicity, but also investment and operational costs, we propose UAE for further scaling up.…”

In this study, the recovery of polyphenols from olive oil mill and winery waste was investigated. The performance of ultrasound assisted extraction (UAE), microwave assisted extraction (MAE), and pressurized liquid extraction (PLE) was assessed using ethanol–water mixtures, which are compatible with food, nutraceutical, and cosmetic applications. The extraction efficiency from olive pomace and lees samples was evaluated in terms of total polyphenol content (TPC), determined by high performance liquid chromatography (HPLC) and Folin–Ciocalteu assay. The effect of solvent composition, temperature, and time was analyzed by response surface methodology. Ethanol:water 50:50 (v/v) was found to be a suitable solvent mixture for both kinds of samples and all three extraction techniques. The performance of the extraction techniques was evaluated, under optimal experimental conditions, with a set of different representative samples of residues from olive oil and wine production. Overall, the best extraction efficiency for olive pomace residues was provided by MAE (ethanol:water 50:50 (v/v), 90 °C, 5 min), and for wine residues by PLE (ethanol:water 50:50 (v/v), 100 °C, 5 min, 1 cycle). However, the results provided by UAE (ethanol:water 50:50 (v/v), 30 min) were also suitable. Considering not only extraction performance, but also investment and operational costs, UAE is proposed for a future scaling up evaluation. Regarding olive pomace as a source for natural phenolic antioxidants, olive variety and climatic conditions should be taken into account, since both influence TPC in the extracts, while for winery residues, lees from red wines are more suitable than those from white wines.

“…Indeed, solvents such as ethanol and methanol can be produced from carbon-neutral homoacetogenic gas fermentation [43] and biogas produced from wastes, respectively, strengthening the sustainability of such process. This alternative PLE technique should be considered as a promising eco-friendly extraction process for natural products from biological samples [5,[24][25][26]39,44]. It also opens the way to further optimizations to the solvent mixture to use for isolating specific polyketide red pigments.…”

Many species of Talaromyces of marine origin could be considered as non-toxigenic fungal cell factory. Some strains could produce water-soluble active biopigments in submerged cultures. These fungal pigments are of interest due to their applications in the design of new pharmaceutical products. In this study, the azaphilone red pigments and ergosterol derivatives produced by a wild type of Talaromyces sp. 30570 (CBS 206.89 B) marine-derived fungal strain with industrial relevance were described. The strain was isolated from the coral reef of the Réunion island. An alternative extraction of the fungal pigments using high pressure with eco-friendly solvents was studied. Twelve different red pigments were detected, including two pigmented ergosterol derivatives. Nine metabolites were identified using HPLC-PDA-ESI/MS as Monascus-like azaphilone pigments. In particular, derivatives of nitrogen-containing azaphilone red pigment, like PP-R, 6-[(Z)-2-Carboxyvinyl]-N-GABA-PP-V, N-threonine-monascorubramin, N-glutaryl-rubropunctamin, monascorubramin, and presumed N-threonyl-rubropunctamin (or acid form of the pigment PP-R) were the major pigmented compounds produced. Interestingly, the bioproduction of these red pigments occurred only when complex organic nitrogen sources were present in the culture medium. These findings are important for the field of the selective production of Monascus-like azaphilone red pigments for the industries.

“…24 Nonetheless, although some processes are often claimed to be "green", the quantification of the environmental performance of different extraction technologies is limited to a few examples. 25,26 In this regard, a nontrivial result has been recently provided by Carlqvist et al, who highlighted that striving for the highest yield is not always optimal from a life cycle point of view. 27 In the present study, we focused on pine needles, PN, a largely available and underexploited biomass resource for the extraction of active compounds, such as polyphenols and, in particular, condensed tannins.…”

Polyphenols are natural organic compounds with many possible applications because of their unique biological activities. They can be extracted from a wide variety of waste biomasses, and a great deal of interest exists in identifying extraction processes optimized in terms of both yield and environmental impact. In this framework, we have compared three techniques, namely, maceration and extraction assisted by either ultrasounds or microwaves, for the extraction of phenolic compounds from dry pine needles, largely available and underexploited biomass. The yields in terms of total phenolic compounds and condensed tannins were assessed as a function of the extraction time, and a life cycle assessment (LCA) approach was adopted for quantifying the environmental impacts of the three techniques. Despite being time-consuming, maceration is the least-impact method, immediately followed by (much faster) ultrasound-assisted extraction. The energy intensity is mainly responsible for the overall eco-profile of the three techniques, whose hotspot resulted to be electricity consumption. Short processing time is hence crucial, as the gains in terms of yield achievable by prolonging the extraction processes bring about energy burdens that nullify the environmental advantages. Even the choice of "greener" solvents (e.g., ethanol instead of acetone) appeared questionable, as the extraction yield has an impact greater than the "greenness" of the raw materials.
