OIL EXTRACTION FROM RAPESEED OIL USING SOXHLET
Extraction of Oil from Rapeseed Whole using Soxhlet Apparatus: A Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the
The flow chart for aqueous enzymatic extraction of rapeseed oil is shown in Fig. 1. As such, the dehulled rapeseed were first treated by an electric near-infrared oven at 120°C for 30 min to inactive the native myrosinase and enhance rapeseed oil flavor, followed by dry grinding for 5 min in a DFY-400 grinder to ruptured the cell wall.
Extraction, Isolation of Bioactive Compounds and Therapeutic
The oil is obtained from rapeseed by extraction with n-hexane. The antibacterial activity of rapeseed oil was studied on four microorganisms, namely Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa and Klebsiella pneumonia, causing some infections.
2.1.1 Solvent-Extracted Rapeseed Meal. Rapeseeds have 40–45% oil, and when wholly crushed and extracted by solvent, produce about 60–55% oil meal. Rapeseed cake, as a residue, usually has 10–25% oil, but rapeseed meal subjected to extraction has only a few percent of the oil [].
Rapeseed proteins for technical applications: Processing
Additionally, the solvent-free extraction of oil can be performed by enzyme-assisted aqueous extraction. The method has been tested for rapeseed by a few authors using different enzyme combinations and conditions. It was possible to extract up to 90 % of free oil using a combination of cellulase, pectinase and β-glucanase (Zhang et al., 2007
Effect of enzyme treatment at low water content on oil extraction and oil quality. Table 2 summarises the water contents of the flaked rapeseeds before and after addition of 1:1 mixtures of CC and VZ at enzyme dosages of 0.05–0.5 mL per 100 g rapeseed. The water content of the untreated rapeseeds was significantly lower than that of rapeseeds
An advanced aqueous method of extracting rapeseed oil with
Because of concern about environment, health, and cost, research into the production of rapeseed oil by aqueous extraction has been promoted. The advanced aqueous extraction method using a 1.5:10 water-to-rapeseed kernel slurry ratio without the addition of any chemical which was finally developed in this study recovered 94.73% rapeseed oil with high quality.
Rapeseed/canola is a raw material for vegetable oil and extraction meal as feed, food and fuel. The oil is mainly used as a high-value salad oil for dressings etc. due to its high contents of oleic acid (ca. 60%) and poly-unsaturated linolenic acid (omega-3, ca. 10%).
Impact of instant controlled pressure drop pre-treatment on
World productionof rapeseed seed amountsis about 5 mil-lion tons/year, taking the 5th place among oilseed crops (USDA, 2013). For rapeseed oil extraction, industries employ and even combine both mechanical (pre-press) and solvent ex-traction methods. In industrial process, residual oil content in rapeseed meal is around 2% (Lomascolo et al., 2012).
Introduction Rapeseed is one of the most important oil crops, ranking as the second leading source of edible oil production in the world. 1 Rapeseed oil contains a relatively high content of polyunsaturated fatty acids and natural biologically active compounds (tocopherols, phytosterols and polyphenols) with potential health benefits. 2 Rapeseeds are rich in polyphenols, and their polyphenol
