Ultrasound-assisted extraction of phytocompounds from dragon fruit peel: Optimization, kinetics and thermodynamic studies

Mass transfer, kinetics, and thermodynamics studies during the extraction of polyphenols from Feijoa sellowiana peels

“…Our findings (∆H > 0, ∆S > 0, and ∆G < 0) of thermodynamic analyses are compatible with those of Yedhu Krishnan and Rajan (Krishnan & Rajan, 2017;Yedhu Krishnan & Rajan, 2016), Lee and Kim (2019), Xi et al (2019), Bhagya Raj and Dash (2020 favored the spontaneity of the extraction according to their Gibbs free energy changes.…”

Ultrasound-homogenization-assisted extraction of polyphenols from coconut mesocarp: Optimization study

“…When the ultrasonic power, temperature and time reach a certain threshold, the cell wall rupture caused by the ultrasonic effect tends saturated. However, the extensive ultrasound degraded and destroyed phenolic compounds extracted from CM and CE, resulting in the thermal degradation of phenolic compounds [19] . Previous reports on the yield of phenolic compounds extracted from olive fruits using the UAE also demonstrated increase of yield with increasing time from 4 to 20 min, whereas prolonged treatment of ultrasound after 20 min declined the yield [34] .…”

“…In addition, Ultrasound-Assisted (UAE) and Homogenization-Assisted Extraction (HAE) are considered to be the main methods for efficient extraction of natural active ingredients. The UAE is to use the cavitation, thermal and mechanical effect of ultrasonic to strengthen the treatment of materials [17] , [18] , [19] , which effectively destroys the cell wall structure and promotes the intermolecular diffusion, resulting in fully release the active intracellular substances [20] , [21] . It has the advantages of short extraction time, less solvent consumption, and high extraction rate [22] , [23] .…”

Application of artificial neural network‐genetic algorithm and response surface methodology for optimization of ultrasound‐assisted extraction of phenolic compounds from cashew apple bagasse

“…Studies have already reported on the application of RSM modeling for the UAE of bioactive compounds from Ziziphus jujube (Jujube) seed (Wu et al, 2019), Syzygium cumini (Jamun) seed (Mahindrakar & Rathod, 2020), Hylocereus undatus (Dragon fruit) peel (Raj & Dash, 2020), Mangifera indica (Mango) peel (Martínez-Ramos et al, 2020), and Psidium cattleianum sabine (Strawberry guava) peel (Meregalli et al, 2020). Also, recent studies are focusing on simultaneous implementation of RSM and ANN-GA for the simulation and optimization of UAE of bioactive compounds from different products such as garlic (Ciric, Krajnc, Heath, & Ogrinc, 2020), meghalayan cherry fruit (Kashyap, Riar, & Jindal, 2021), longan fruit (Wen, Yang, Cui, You, & Zhao, 2012).…”
