“…Obvious differences between values can also be attributed to effect of diffusivity and concentration or solvent saturation in the extractions. The diffucion rate determined the length of time needed to achieve equilibrium in the extracting medium and an increase of the solvent to vegetable material increases the mass ratio of the bioactive compounds extracted (Wu, Li, Chen, Wang, & Lin, 2020).…”

“…While the formation of free-radicals during US processing is considered a main disadvantage of the technology as it affects the bioactivity of components such as phenols [ 83 ], chemical modification such as increasing the extent of hydroxylation of flavonoids [ 84 ] can enhance the antioxidant activity or at least counteract some of the negative effects of free radicals. This led to the fact that optimum US processing conditions where maximum yield and bioactivity could be optimized for various materials.…”

“…Furthermore, the inhibitory effect of α-amylase of the combined technique was increased up to 37% compared to US and HPP with 34% and 29% [ 67 ]. The better outcome achieved by the combined technologies can be explained by the more efficient disruption of plant cell walls by US and the improved diffusion caused by HPP that enhances the release of bioactive compounds compared to their individual potentials [ [83] , [84] , [116] ]. A method combined US with MW confirmed that they could enhance the oil extraction from tea ( Camelia sinensis ) seeds.…”

“…To date, conventional organic solvents, such as ethanol, acetone, and chloroform, remain the most commonly used solvents to extract bioactive compounds from plant materials [ 9 , 10 ]. However, some organic solvents have several distinct disadvantages, such as high cost, high level of residue, and toxicity [ 10 , 11 ].…”
