Cold-pressed rapeseed (Brassica napus) oil: Chemistry
There are two types of methods to extract the oil from the seeds, namely solvent extraction and pressing. Solvent extraction is suitable for the seeds with oil content lower than 20%, such as soybean. Pressing is suitable for the seeds with high oil content, such as rapeseed. However, there is residual oil in the meal by using the pressing method.
Therefore, solvent extraction gives an accurate oil content of the samples, by comparing the oil extraction yield from treated and untreated pressed rapeseed. Solvent extraction is the most efficient method with high extraction yield, but this method may cause plant security problems, emissions of volatile organic compounds into the atmosphere
The Effects of Oil Extraction Methods on Recovery Yield
For hot-pressed rapeseed oil production, there are several additional process steps after the pressing and solvent treatment to refine the oil and prolong the shelf life . The dominating protein groups in rapeseed are the storage proteins napin (albumin) and cruciferin (globulin) which together constitute 85% to 90% of the total proteins.
Currently, solvent extraction is the most economical, efficient, and widely used in rapeseed oil-processing industry due to the high oil recovery. Although the solvent extraction has highly increased the oil-extraction rate of rapeseed compared to the conventional mechanical pressing process [Citation 1]; however, it still cannot overcome the

method for recovery of rapeseed oil extracted by the HECS method, and to study the influence of the separation temperature (þ13, þ5, and 20°C) on the quantity and composition of obtained oil- and solvent-rich phases. 2 Materials and methods The full experimental procedure is presented in Figure 1. 2.1 Seed preparation for oil extraction
OIL EXTRACTION FROM RAPESEED OIL USING SOXHLET
Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. Discover the world's research 25+ million members
Above all, the optimal conditions for oil extraction from rapeseed and other seeds have been determined.n-Hexane, which has a relatively low boiling point (69 °C), is the commonly-used petroleum-based solvent for extraction of vegetable oils. It has been selected as an excellent extraction solvent for many years due to its nonpolar properties
Texturing and Instant Cooling of Rapeseed as Pretreatment
Solvent Oil Extraction from Ground Rapeseeds Global Approach from Solvent Oil Extraction. The results of solvent oil extraction from ground rapeseed powder were shown in Table 2. ASE yields obtained from raw material were higher than those obtained in 8 h by DM. They were 623.4 ± 1 and 440.8 ± 0.4 g oil/kg ddb, respectively.
Rheological behavior of six crude rapeseed oils with different extraction methods including hot-pressing, solvent-extraction and cold-pressing were studied. Viscosities of the oils were measured with shear rates ranging from 0.1 to 200 s−1 at three different temperatures. The Casson model was used to fit the experimental data and the Arrhenius equation was applied to estimate the energy of
