“…The possible reason is that ultrasonic frequency of 80 kHz is closer the resonant frequency of the target component cell. Similarly, our previous studies [41][42][43] also found a highest extraction yield at one optimal frequency during the extraction of rutin from Sophora japonica and hesperidin from tangerine peels. Thus, 80 kHz as the optimum ultrasonic frequency is used for the UAE of quercetin and rutin.…”

Ultrasonic-assisted extraction (UAE) of quercetin and rutin from the stalks of Euonymus alatus (Thunb.) Sieb in our laboratory, which aimed at evaluating and optimizing the process parameters, was investigated in this work. In addition, process parameters such as ethanol solution concentration, solvent volume/sample ratio, ultrasound power and extraction time, ultrasound frequency and extraction temperature were also first applied for evaluating the influence of extraction of quercetin and rutin. Optimum process parameters obtained were: ethanol solution 60%, extraction time 30 min, solvent volume/sample ratio 40 mL/g, ultrasound power 200 W, extraction temperature 30 • C and ultrasound frequency 80 kHz. Further a hybrid predictive model, which is based on least squares support vector machine (LS-SVM) in combination with improved fruit fly optimization algorithm (IFOA), was first used to predict the UAE process. The established IFOA-LS-SVM model, in which six process parameters and extraction yields of quercetin and rutin were used as input variables and output variables, respectively, successfully predicted the extraction yields of quercetin and rutin with a low error. Moreover, by comparison with SVM, LS-SVM and multiple regression models, IFOA-LS-SVM model has higher accuracy and faster convergence. Results proved that the proposed model is capable of predicting extraction yields of quercetin and rutin in UAE process.

“…When the ultrasonic power was greater than 180 W, the yield started to decrease slightly. The excessive number and size of the bubbles at high ultrasonic power may be too big to collapse which may result in the reduction of cavitation effect or may restrain the transmission of the ultrasonic waves from the probe to the cell wall [4,22]. However, when the ultrasonic power increased excessively, the heat produced by the ultrasound cannot be removed in short times even the temperature was kept as constant as possible [22,30].…”

“…Above this ratio, no significant change in the yield was observed. This phenomenon can be considered as the equilibrium reached in terms of mass transfer between the solid and the liquid [2,22].…”

“…The solvent extraction has some disadvantages such as a long extraction time with low efficiency. Therefore, some novel methods were developed for the extraction of lycopene such as supercritical fluid extraction (SFE) [18,19], microwave assisted extraction (MAE) [20], and ultrasonic assisted extraction (UAE) [2,4,8,21,22]. Among these methods, SFE and MAE require high energy consumption and expensive equipment whereas UAE is a promising and commercially applicable extraction method with less extraction time and low cost for equipment.…”

The extraction of lycopene from dried tomato powder was carried out using ultrasound assisted (UAE) and conventional solvent (COSE) extraction methods with varying liquid/solid ratio (10:1-50:1), extraction time (5-60 min), temperature (20-50C) and ultrasonic power (150-200 W). The response surface methodology was used to optimize the extraction parameters and to determine their individual and interaction effects on the extraction yield. The maximum extraction yields of UAE (722.321 mg lycopene/kg tomato powder) and COSE (975.833 mg lycopene/kg tomato powder) was observed using the following conditions: 166 W for 26 min, and a 56:1 liquid/solid ratio, and 45C for 50 min, and a 56:1 liquid/ solid ratio, respectively. At the same extraction conditions UAE is reaching the same extraction yield faster than the COSE. Even the lycopene contents of the extracts were the same, the antioxidant capacity of the UAE and COSE extracts were 12.48 and 11.08 mg Trolox/g tomato powder, respectively.

“…Among the different existing techniques, UAE has been widely recognized as a safe, effective, inexpensive, and environment-friendly technology. When it is applied in the solid-liquid extraction process, it has been proven to be capable of reducing the consumption of solvent, shortening the extraction time, and improving extraction yields [12][13][14][15]. This is mainly attributed to the ultrasonic cavitation, which can generate cavitation bubbles in liquid medium and result in macro-turbulence, high-velocity flow, and perturbation in micro-particles of the biomass [16].…”

This work focused on the intensification of extraction process of glycyrrhizic acid (GA) from Glycyrrhiza uralensis using ultrasound-assisted extraction (UAE) method. Various process parameters such as ultrasonic power, ultrasonic frequency, extraction temperature, and extraction time which affect the extraction yield were optimized. The results showed that all process parameters had exhibited significant influences on the GA extraction. The highest GA yield of 217.7 mg/g was obtained at optimized parameters of 125 W, 55 kHz, 25 • C, and 10 min. Furthermore, the extraction kinetics model of this process was also investigated based on Fick's first law available in the literature. Kinetic parameters such as equilibrium concentration (C e ) and integrated influence coefficient (λ) for different ultrasonic powers, ultrasonic frequencies, and extraction temperatures were predicted. Model validations were done successfully with the average of relative deviation between 0.96% and 4.36% by plotting experimental and predicted values of concentration of GA in extract. This indicated that the developed extraction model could reflect the effectiveness of the extraction of GA from Glycyrrhiza uralensis and therefore serve as the guide for comprehending other UAE process.
