“…The extraction time in MAE represents the time length the sample is exposed to microwave irradiation. In a long extraction time, the sample is exposed to microwave irradiation longer which causes more ruptures in sample tissues and plant cell walls leading to an increase in phenolics released [ 30 ]. Hence, the extraction yield of the phenolics and antioxidant properties increased in response to increasing the extraction time.…”

The lemon-scented tea tree (LSTT) is an Australian native herb and is a rich source of essential oil and phenolics. The ETHOS X extraction system is known as a commercial microwave-assisted extraction (MAE) system for extracting bioactive compounds from plant materials. This study investigated the influence of soaking time, radiation time, microwave power, and sample to solvent ratio on the extraction efficiency of polyphenols and antioxidant properties from lemon-scented tea tree leaves and optimized the extraction conditions using response surface methodology (RSM). The effectiveness of ETHOS X was further compared with ultrasound-assisted extraction (UAE) and shaking water bath (SWB) techniques. The results revealed that soaking time did not significantly affect the recovery of phenolics from the leaves (p > 0.05). Thus, soaking is not required for the ETHOS X extraction of polyphenols from LSTT leaves. RSM was successfully applied to explore the impact of ETHOS X extraction conditions and optimize the extraction conditions. Radiation time significantly affects the recovery yield of phenolics (p < 0.05) positively, whereas irradiation power and sample to solvent ratio adversely influenced the extraction yields of phenolics. The optimal ETHOS X extraction conditions were: radiation time of 60 min, irradiation power of 600 W, and sample to solvent ratio of 2 g/100 mL. Under these conditions, 119.21 ± 7.09 mg of phenolic, 85.31 ± 4.55 mg of flavonoids, and 137.51 ± 12.52 mg of proanthocyanidins can be extracted from a gram of dried LSTT leaves. In comparison with UAE and SWB, ETHOS X is not more effective for the extraction of phenolics than UAE and SWB. However, this technique can save half of the solvent volume compared to UAE and SWB techniques.

A BSTRACT Clinacanthus nutans ( C. nutans ) is an edible profitable herb with high phenolic content that recognized herb relieves skin disorder, antityrosinase, and anticancer. Along with these health benefits C. nutans , however, there is no study on the factors that influence the phenolic content of C. nutans extraction by water-based ultrasonic-microwave-assisted extraction (UMAE). The aim of this study evaluates UMAE conditions (ultrasonic power, microwave power, and extraction time) on responses using response surface Box–Behnken design and compared with the hydrothermal extraction. The findings found that the caffeic acid and ferulic acid content decrease with increasing the microwave power and long extraction time ( P <0.05). The combination factors significant impact on the phenolic compound are microwave power with a time of extract and ultrasonic with microwave power ( P <0.05). The optimization UMAE of C. nutans was ultrasonic power 150 W, microwave power 50 W, and time of extraction 3 min ( P < 0.05), and final temperature after extraction should be <60°C. UMAE was a four-fold greater target response and a sixty-fold lower extraction time compared to conventional hydrothermal extraction. The synergistic of ultrasonic and microwave power encourages extraction efficiency, which is advantageous to prepare the high-quality C. nutans extracted raw materials to apply in the nutraceutical, pharmaceutical, and cosmetic industry.

“…Furthermore, heating of the water molecules inside the plant matrix expands cellular materials and facilitates the release of the cell contents when the structure is broken (Maroun et al, 2018). MWs have been widely used to extract various phytochemicals, such as tannins, alkaloids, and saponins, from different plant sources (Xiaokang et al, 2020). Dalmoro et al (2018) showed that MW pretreatment (60−75 • C 1000 W, 2.45 GHz, 1 min) reduced the tannin content with minimum impact on the structure of legume seeds.…”

Current demand of consumers for healthy and sustainable food products has led the industry to search for different sources of plant protein isolates and concentrates. Legumes represent an excellent nonanimal protein source with highprotein content. Legume species are distributed in a wide range of ecological conditions, including regions with drought conditions, making them a sustainable crop in a context of global warming. However, their use as human food is limited by the presence of antinutritional factors, such as protease inhibitors, lectins, phytates, and alkaloids, which have adverse nutritional effects. Antitechnological factors, such as fiber, tannins, and lipids, can affect the purity and protein extraction yield. Although most are removed or reduced during alkaline solubilization and isoelectric precipitation processes, some remain in the resulting protein isolates. Selection of appropriate legume genotypes and different emerging and sustainable facilitating technologies, such as high-power ultrasound, pulsed electric fields, high hydrostatic pressure, microwave, and supercritical fluids, can be applied to increase the removal of unwanted compounds. Some technologies can be used to increase protein yield. The technologies can also modify protein structure to improve digestibility, reduce allergenicity, and tune technological properties. This review summarizes recent findings regarding the use of emerging technologies to obtain high-purity protein isolates and the effects on technofunctional properties and health.
