There are two methods to separate oil from oilseeds: crushing in mechanical screw press or extraction with solvent. Before oilseed pressing, pretreatment is also important especially for
Comparison of oil extraction between screw press and solvent
The authors concluded that the n-hexane extraction technique was more efficient than screw press technique. of seeds caused by microbial growth and chemical changes [19].
It was shown that a better raffia quality oil is extracted using a screw press, than using a solvent extraction by Soxhlet. The press raffia oil presented: (i) a lower content of total SFA, (ii) a richer content of total MUFA,
Comparison of oil extraction between screw press and solvent
An experimental investigation was conducted to evaluate the effects of the processing of the raw materials, such as preparation and extraction, grating (whole and grated), drying and moisture

- What is the difference between screw press and solvent extraction?
- It has been found that the oil yield obtained by the solvent extraction technique was higher in comparison to the mechanical (screw) pressing (Bargale et al., 1999; Willems et al., 2008). The mechanical screw press technique was found inefficient because of the lower yield of oil.
- Which is better screw press or n-hexane method?
- Relative advantages and disadvantages of oil extraction between screw press and n-hexane techniques. In comparison to both methods, the results showed that n-hexane method is better in terms of higher oil yield as well as fossil energy ratio.
- What is solvent extraction?
- Solvent extraction is capable of removing nearly all the available oil from oil-seeds or nuts. About 98% of the oil is being extracted by solvent method. . In addition to the high yield of oil, the method produces oil with better qualities, and a higher protein meal .
- Is screw press oil extraction effective?
- Mahanta and Shrivastava (2004) stated that the oil extraction using screw press is not effective which is due to the problem involved in non-edible seed kernel. In contrary, the n-hexane technique was found more efficient which was due to the higher yield of oil and its consistent performance.
- How to maximize oil yield using screw press and n-hexane techniques?
- These dried kernels were used to maximize the yield of oil using screw press and n-hexane techniques. The results indicated that the higher yield of oil was obtained at 14.4 % MC with the dried kernels in every case (both WKs and GKs) using screw press and nhexane techniques.
- What is the colour of oil extracted using screw press method?
- The colour of the oil extracted using screw press method was dark green and the colour of the oil extracted using n-hexane technique was yellow. The physico-chemical properties, such as cetane number, the heat of combustion and viscosity are greatly influenced by the fatty acid composition of BLO.
