Solid–liquid extraction from plants — experimental kinetics and modelling

Improvement of Soybean Oil Solvent Extraction through Enzymatic Pretreatment

“…As it can be observed, the magnitude order of the estimated diffusion coefficients was between 10 −11 and 10 −10 m 2 ·s −1 , which coincides with previous data [19][20][21][22][23][24][25][26][27]. Varzakas et al [5] compiled effective diffusion coefficients in magnitude orders between 10 −12 and 10 −10 m 2 ·s −1 for a wide variety of solid foods, and so did Doulia et al [19].…”

Grape marc phenolics: Extraction kinetics, quality and stability of extracts

“…One of the higher-value options is the recovery of bioactive plant food constituents such as polyphenols, which have antioxidant properties and could be used in the pharmaceutical, cosmetics and food industries. In spite of the numerous studies found in the literature on solid-liquid extraction (the most commonly used technology) of natural antioxidants from plant materials, data on the optimisation, modelling and simulation of this process are scarce, and often optimisation has been carried out by statistical approaches (Bucić -Kojić et al, 2007;Cacace and Mazza, 2003;Herodež et al, 2003;Ku and Mun, 2008;Liao et al, 2008;Pinelo et al, 2005;Simeonov et al, 1999;Spigno and De Faveri, 2009). However, there is a need for mathematical modelling, which, as a useful engineering tool, considerably facilitates the optimisation, simulation, design and control of processes and contributes to better utilisations of energy, time and solvent.…”

On-line monitoring of Soxhlet extraction by chromatography and mass spectrometry to reveal temporal extract profiles

“…The available extraction methods can be classified according to the nature of the sample and extractant phases. The most common extraction modes include solid-liquid extraction [2][3][4] and liquid-liquid extraction [5,6]. Soxhlet extraction is one of the well-established and widely used extraction methods [7,8].…”
