Castor Oil: Properties, Uses, and Optimization of Processing Parameters
Castor oil seed contains about 30%–50% oil (m/m).74,75 Castor oil can be extracted from castor beans by either mechanical pressing, solvent extraction, or a combination of pressing and extraction.74 After harvesting, the seeds are allowed to dry so that the seed hull will split open, releasing the seed inside.
The largest world producer and exporter of castor oil is India, with about 70% of the total exports, followed by China 15%, Brazil 8% and Thailand 1%, whereas countries such as USA, Russia and Japan are the major importers [4]. Steam distillation, hydro distillation and solvent extraction are the methods being employed for extracting castor oil.
Solvent Extraction of Castor Beans Oil
The conditions for ethanol extraction that gave high oil yield were as follows: extraction temperature of 70°C, extraction time of 7 h, solvent-to-solid ratio of 6 : 1, particle size of 0.5–0.8
From the seed of castor (Ricinus communis L.), a hydroxylated oil is extracted to be used as raw material for an extensive list of products in the chemical industry. The industrial process for castor oil extraction produces the oil, as the main product, and generates large quantity of castor meal as a protein-rich by-product.
Bioactive Phytochemicals from Castor (Ricinus communis Linneo) Seed Oil
A summary of reported bioactive compounds in the extracts of castor plant parts with applied solvent systems and reported biological activities is shown in Table 1.The leaves of the castor plant contain about ±50 phytochemicals, in addition to about five different essential oils, while the roots are reported to contain ±10 different phytochemicals [].
Mechanical extraction is one of the oldest methods used for oil ex traction. In principle, the seeds. are placed between barriers where the volume available to the seed is reduced by pressing
Optimization Methods for the Extraction of Vegetable Oils: A Review - MDPI
The three major steps involved in solvent extraction are oilseed cleaning and conditioning, oil extraction, and separation of the miscella. Crude oil and meal quality depend mostly on type of solvent used, reaction temperature, and type of pretreatment given to the oilseed [25, 26].
This paper carried out experimental study, through extraction and characterization of both crude and refined castor oil. Normal hexane was used as solvent for the extraction process. The oil produced was refined through degumming, neutralization and bleaching process using local adsorbent (activated clay).
Comparative Extraction of Castor seed Oil Using Polar and Non polar
C. Oil Extraction 20g of dry ground seeds were used for the extraction of oil with hexane as solvent. The oil was extracted at 1:3, 1:6 and 1:9 solid (sample) to solvent ratios and different extraction periods i.e. 8h, 10h, 12h and 14h. The solvent was then evaporated using rotary evaporator. Oil yield was calculated based on the oil weight.
This study shows that the fatty acid composition and tocol content of extracted castor seed oils depend on the castor plant variety and the solvent extraction. The seed oil yield and sterol content were higher when ethanol was used as the extracting solvent than when hexane was used for both varieties of plants studied. While castor oil
- How is castor oil extracted?
- Castor oil seed contains about 30%¨C50% oil ( m/m ). 74, 75 Castor oil can be extracted from castor beans by either mechanical pressing, solvent extraction, or a combination of pressing and extraction. 74 After harvesting, the seeds are allowed to dry so that the seed hull will split open, releasing the seed inside.
- What are the by-products of castor seed oil processing?
- Seeds are commonly used for the extraction of oil, thus, a large number of by-products are obtained from them. The major by-products originating from castor (Ricinus communis Linneo) seed oil processing are oil cake and plant residues such as husks, leaves, roots, and stems, after seeds have been harvested and processed.
- How does oil extraction affect the properties of Castor meal proteins?
- The industrial process of oil extraction affects properties of castor meal proteins. The step of solvent evaporation reduces the nematicide efficiency of castor meal. Sheep tolerated solvent-extracted castor meal without additional detoxification. Sieved castor meal has high protein (60.2%) and low fiber (6%) content.
- Is Castor a plant?
- Castor (Ricinus communis Linneo) belongs to the plant family of Euphorbiaceae and is a crop intensively cultivated to produce oil from its seeds. There is a high demand of oil on the international market since oil extraction is economically favorable and oil has versatile applications in industry.
- What is castor oil?
- Castor oil is increasingly becoming an important bio-based raw material for industrial applications. The oil is non-edible and can be extracted from castor seeds from the castor plant belonging to the family Euphorbiaceae. The oil is a mixture of saturated and unsaturated fatty acid esters linked to a glycerol.
- What are castor seeds used for?
- The plant produces castor seeds that contain up to 50 % castor oil by weight. The oil can easily be extracted from castor seeds and find its use in a multitude of sectors such as medicine, chemicals industry and in other technologies [ 1 ].
