“…DIC-assisted extraction of anthocyanins from Roselle calyces was studied by Benamor et al [25], who demonstrated that extraction kinetics and yields of these compounds were increased by the DIC process. They also noticed the impact of DIC treatment on extraction of oligosaccharides (stachyose and ciceritol) from the seeds of the Indian Tephrosia purpurea plant [27]. Compared to extraction where the sample was not pre-treated by DIC, an improvement of solid-fluid extraction of the compound of interest was shown in these studies.…”

This review presents useful and green techniques of solvent-free extraction used in ancient times, such as extraction of olive oil and citrus essential oil, and innovative techniques, such as pulsed electric field, microwave, instantaneous controlled pressure drop, and extrusion. We discuss the devices, their applications, mechanisms, and parameters influencing sample preparation prior to analysis of natural products.

“…Tephrosia seeds Ciceritol 0.6 mPa, 240 s, 1 cycles HPLC-DAD [27] used as pretreatment can open these strongboxes of cells to make their contents more available and make the determination of the composition more realistic. A similar situation can be achieved using DIC treatment.…”

Instant controlled pressure drop process (DIC) was used to texture rapeseeds in order to intensify oil extraction performances of both pressing and solvent extraction processes. Solvent extraction from both DIC-textured and non-treated raw material RM seeds was achieved with n-hexane using separately accelerated solvent extraction (ASE) and dynamic maceration (DM). ASE allowed quantifying the extraction yields while the extraction kinetics issued from DM experimental data was studied through coupled washing/diffusion CWD phenomenological model. ASE oil contents were 622.5 ± 0.5 and 664.4 ± 0.5 g oil/kg dry dry basis ddb for untreated and DIC-textured seeds, respectively. In terms of kinetics, 45-min DM of DIC-treated seeds implied higher yields than 8-h DM of RM (467.8 ± 0.5 against 435.6 ± 0.5 g oil/kg ddb). Moreover, pressing oil yields reached 553.5 ± 0.5 against 490 ± 0.5 g oil/kg ddb for DIC and RM seeds, respectively. Besides, optimized DIC treatment allowed obtaining preservation of lipid fatty acid profiles.

“…As already shown, a stirred external solvent can immediately dissolve the solute that is initially accessible on the exchange surface, to remove it far from the plant, usually by convection [22][23][24]. Therefore, in any solvent extraction operation performed on a porous solid material, the first interaction between the solvent and the exchange surface, so-called "washing," takes place during a short period of time [25].…”
