“…Besides the type of solvent, temperature, solid-liquid ratio, particle size, and agitation are important parameters for the extraction of solids from food or plant matrices. There are several studies on the extraction behavior of different plant materials, such as coffee bean , soy bean (Dagostin et al, 2015;Cheng et al, 2018), neem seed (Adewoye and Ogunleye, 2012), aniseed (Scopel et al, 2016), avocado (Krumreich et al, 2018), pongam seeds (Kumar et al, 2018), pequi and murici seeds (Araújo et al, 2018), and walnuts (Chen et al, 2018). These studies were conducted with aqueous or organic solvent extraction including the parameters afore mentioned.…”

Oil recovery, retention index, and thermodynamic parameters of green coffee beans (GCB) and its press cake (PC) extraction using bio-based solvents were investigated. The extraction parameters investigated were temperature (35 to 55 °C), type of material (coffee beans and press cake), and type of solvent (ethanol, acetone, and ethyl acetate), at a fixed solvent to solid mass ratio (5:1) (w/w). The fatty acid profile of the ethanolic extract was assessed for both GCB and PC, and compared to the oil obtained from the mechanical pressing. It was observed that higher temperatures affected positively the extraction yields, especially when acetone and ethanol were employed, allowing a recovery up to 90% and 56.7% for GCB and PC, respectively. The solution retained in the raffinate phase from the GCB extraction was greater than that for the PC. For all operational levels, the ∆H and ∆S were positive. ∆G decreased with increasing temperature. Palmitic and linoleic acids were predominant in all types of oil. The oil obtained by pressing showed higher content of linoleic acid (45.32%), while the solventextracted oil from GCB had more palmitic acid (34.79%), and the PC oil presented intermediate levels of all the methyl esters.

“…In HD7, traces of feniculin were also identified, in addition to traces of D-limonene and estragole. Estragole (Chouksey et al, 2013;Howes et al, 2009;Wang et al, 2011;Wong et al, 2014), D-limonene (Chouksey et al, 2013Padmashree et al, 2007;Zhai et al, 2009) and feniculin (Chouksey et al, 2013;Scopel et al, 2016;Singh et al, 2006) are naturally occurring compounds present in the edible star anise essential oil.…”

“…The supercritical fluid extractions were performed in an extraction vessel (Waters) with 500 mL capacity, 6.3 cm diameter and 19 cm height. The investigated conditions were determined according to previous works range in order to obtain the volatile extracts using the SFE methodology: four different pressures (80, 90, 100 and 110 bar) at 40 °C, with a 1000 g.h -1 CO2 flow rate [22][23][24] and 0.2 kg of ginger rhizome. For the highest essential oil yield, the experimental extraction curve, the plot of the cumulated extract versus the extraction time, was built in triplicate aiming to enable the mathematical modeling.…”

This study aims to find the best conditions for the extraction of Zingiber officinale essential oil using the supercritical fluid extraction (SFE), steam distillation (SD) and hydrodistillation (HD) techniques, regarding the maximum oil yield. For the HD technique is evaluated the best ratio between plant mass and water volume and for SFE and SD the pressure condition was investigated. Principal Component Analysis (PCA) was used to evaluate the similarity between the composition of the essential oil in different pressures and extraction methods. The experimental extraction curve was plotted and three different mathematical models were used to fit the data for SD and SFE methods, obtaining the relevant mass transfer parameters. The essential oil compounds were identified by gas chromatography coupled with mass spectrometry (GC-MS), being αzingiberene the main component with different contents (from 11.9 to 28.9%). The best condition for the SFE HIGHLIGHTS  Ginger essential oil was extracted by SFE, SD and HD, modelling was also performed.  Different pressures (SD and SFE) and water volumes (HD) were investigated.  The extraction products were analyzed by GC/MS.  PCA was performed, geranial and α-zingiberene have the greatest covariance.
