Kinetic study of canola oil and tocopherol extraction: Parameter comparison of nonlinear models

Comparison of safflower oil extraction kinetics under two characteristic moisture conditions: statistical analysis of non-linear model parameters

“…The fitted regression models for different moisture levels were compared through their parameters, by using a procedure based on the principle of "extra sum of squares" and "conditional error", with a significance level of 95% (Fernández et al, 2012).…”

“…H 1 : model parameters A and B depend on moisture content (individual parameter model). With the extra sum of squares of each model, the statistic F 0 was obtained, which allowed a comparison of the models referred to each hypothesis (Fernández et al, 2012;Boché and Lavalle, 2004).…”

“…Although kinetic assays have been carried out for decades in order to analyze the behaviors of different oilseeds (Fernández et al, 2012), few studies have been reported in the literature on the kinetic behavior of safflower seed oil extraction (Hu et al, 2012;Han et al, 2009), and none was found on the oil extraction kinetics of dehulled or partially dehulled safflower. The principle of solvent extraction is simple and is based on the fact that a component tends to partition between two phases depending on the equilibrium determined by the conditions and nature of the component and of both phases (Bockisch, 1998).…”

“…The model most used for representing the extraction of oilseed by solvent is a modification of Fick`s Second Law, which takes into account more than one mechanism: washing and diffusion and, in some cases, this second stage is subdivided in two, taking into account unhindered and hindered diffusion (Fernández et al, 2012). Some studies found that first-order kinetics represented this process using Sterculia foetida seeds and algaes as raw material (Sivakumar et al, 2012;Suganya and Renganathan, 2012).…”

Kinetics of extraction and in situ transesterification of oils from spent coffee grounds

“…Prior studies have proven the viability of in situ transesterification method using various feedstocks, including sunflower seeds [33][34], soybean [35] and jatropha curcas [36]. The yields of in situ transesterification processes are influenced by various parameters, such as temperature, catalyst loading, oil to methanol ratio, particle size and moisture [37]. Further, significant differences in production yields have been observed for different feedstocks due to their varying structure.…”
