“…The in‐house equipment consists a stainless steel 18.5 ml inner volume extraction cell in which the stainless steel membrane cartridges filled with 0.5 g of DPN were placed. The solvent mixture (different concentrations of distilled water and ethanol 95%, v/v) was pumped using a HPLC pump (ELDEX OPTOS 2SM, CA) at a mass flow of 5 g/min (Bodoira, Rossi et al., ; Bodoira, Velez et al., ) and preheated up to the extraction set temperature. The system pressure was controlled using a downstream back pressure regulator.…”

“…Recent studies have focused on extraction of phenolic compounds by means of solvents accepted by food industry, for example, water and ethanol, in combination with the assisted extraction techniques such as pressurized liquid extraction, microwave extraction, and ultrasonic assisted extraction (Bodoira, Rossi, Montenegro, Maestri, & Velez, ; Bodoira, Velez, Andreatta, Martínez, & Maestri, ; Caleja, Barros, Prieto, Barreiro Oliveira, & Ferreira, ; Duba, Casazza, Mohamed, Perego, & Fiori, ; Xu, Wang, Liu, Yuan, & Gao, ). Subcritical water extraction (SWE) (also known as pressurized hot water extraction) uses water as solvent between 100 °C and 374 °C.…”

“…The knowledge of the relationships among temperature, pressure, and solvent capacity has allowed to design SFE processes to selectively extract different phenolic compounds from various vegetable matrices such as peanut skin (Bodoira, Rossi et al., ), grape pomace (Aliakbarinan, Fathi, Perego, & Dehghani, ), coriander (Zekovic et al., ), flaxseed (Kanmaz, ), and sesame seeds (Bodoira, Velez et al., ), among others. The benefits of SFE as green technology for extraction of plant biologically active compounds are widely documented in various systematic reviews and meta‐analyses (Bubalo, Vidovic, Redovnikovic, & Jokic, ; Herrero et al., ; Teo et al., ).…”

“…However, interactions among these or other factors are frequently ignored. The response surface methodology (RSM) may be useful to determine the influence of various factors, their levels, and their interactions, in experimental designs involving several factors (Bodoira, Rossi et al., ; Bodoira, Velez et al., ; Caleja et al., ; Kanmaz, ; Yolmeh & Jafari, ; Zekovic et al., ). Generally, RSM has been used for optimizing processes, which can be represented with a second‐order polynomial equation.…”

A process to obtain phenolic compounds with antioxidant properties from pistachio nuts using water/ethanol mixture under high temperature and pressure conditions was carried out. To optimize extraction conditions and antioxidant activity of bioactive compounds, theoretical models were scanned against experimental data. Phenolic profile was dominated by several flavonoids and gallic acid derivatives. A fitted model for phenolic compounds extraction presented a maximum predicted value under the following conditions: 220°C extraction temperature, 6.5 MPa pressure, and 50% ethanol. Beneath these conditions, phenolic extracts gave the highest radical scavenging capacity, similar to that reached by using commercial antioxidants. A mathematical model, namely two-site desorption kinetic model, showed to be suitable for the description of extraction kinetics under the optimal operation conditions. Overall, the process described in this study shows a potential alternative method for extraction of pistachio bioactive compounds.Practical Application: Pistachio nuts are known to contain a vast array of phenolic and polyphenolic substances having strong antioxidant properties. Currently, the use of natural antioxidants in the food industry has increased, in consequence there is a growing interest in improving the extraction processes using GRAS (general recognize as safe) solvents. This study describes a safe, inexpensive, and short-time method (subcritical fluid extraction) to obtain antioxidant extracts from defatted pistachio nuts. This type of process may be adapted toward applications at industrial scale.

“…Pressurized water and ethanol were also used to extract phenolic compounds from olive leaves, and neat ethanol at 463 K proved to be optimal on-the-whole, but a 43:53 mixture at this temperature increased the yield of oleorupein [76]. Pressurized water and ethanol mixtures were also used for extraction from defatted sesame seeds, in this case a 63.5% ethanol mixture at 493 K led to maximal yields of flavones and other phenolic compounds with radical scavenging properties [77]. Brazilian pepper fruits were submitted to PLE with slightly acidified 54.2% aqueous ethanol at 348 K to yield the maximal amount of phenolic compounds [78].…”

Hot, subcritical and supercritical water, methanol, ethanol and their binary mixtures have been employed to treat fuels (desulfurize coal and recover liquid fuels from coal and oil shales) and to extract valuable solutes from biomass. The properties of these solvents that are relevant to their extraction abilities are presented. Various extraction methods: accelerated solvent extraction (ASE), pressurized liquid extraction (PLE), supercritical fluid extraction (SFE, but excluding supercritical carbon dioxide) with these solvents, including microwave-and ultrasound-assisted extraction, are dealt with. The extraction systems are extensively illustrated and discussed.

Sprouts are a source of secondary metabolites as phenolic compounds. Germination and the use of solvents can affect their content. The aim of this work was to identify the total content of phenols and flavonoids in ungerminated and germinated (3, 5, and 7 days) Esmeralda and Perla barley. Different solvents (water, 50% acetone, 80% methanol, 80% ethanol) were used to recover total phenols and flavonoids. The 7‐day germination proved to be ideal for total phenol and flavonoid obtention from Esmeralda barley and the highest total phenol and flavonoid content in Perla variety was observed at 5 and 7 days of germination, respectively. Methanol and ethanol (80%) yielded the highest extraction percentage of total phenols; 50% acetone recovered the highest flavonoid concentrations in Esmeralda barley and 80% methanol in Perla barley. The highest total phenol concentration was obtained from Perla samples at 13.60 mg GAE/g, and the highest total flavonoids were observed in Esmeralda barley at 1.73 mg QE/g. A high correlation was found between the concentration of phenols (0.995) and total flavonoids (0.780) with the radicle size in the Esmeralda samples.
