Nevertheless, castor oil is nonedible and toxic owing to the presence of a toxic protein. rancidity - the oil not turning rancid unless exposed to excessive heat. ) was determined after converting the fatty acids. The fatty acid composition of the biodiesel from mixed oil was analyzed using Gas chromatograph. Yusu. The yield of biodiesel from the experiment was 93.36 % which is very close to the value predicted by the software. castor oil were higher than the values of a standard lubricant (SAE 40 engine oil). lyols. First, there is extra expense in seed. The fatty acid profile of castor Castor oil (Ricinus communis): a review on the chemical composition and One alternative to growing special varieties to improve the oxidative stability of oil is to concentrate oleic acid. To test antioxidants, the, In this study, the fatty acid compositions of Turkish virgin olive oils produced in the Izmir province, an important olive Extraction method e ciency varies according to the moisture content in the seeds as well as extraction temperature. are the weights of castor beans before and after extraction. The first stage involves oil pressing which is done using using screw oil expeller. The composition of Castor oil expelled from Castor seeds evaluated through Gas Chromatograph-Mass Spectrometer (GC-MS) technique. Download full-text PDF ... cultivation and extraction of castor seed oil to harness the economic potential inherent in the plant. The castor oil contains around 90% of the fatty acid and is commercially valued for ricinoleic acid, * Extraction and purification of castor oil from wild Ricinus communis Linn. Full production is reached 8 years after planting. Fourier transform infra-red (FTIR) spectroscopic analysis has confirmed the presence of major functional groups in the oil, notably hydroxyl (3414.12cm-1), carbonyl (1739.85cm-1), olefinic (1659.80cm-1) and methylenic (2925.15cm-1). Rather than the long tedious process of extracting castor oil make more effective use of your time by using the Commercial Oil Extractor. * American Society for Testing and Materials. The fatty acid profile of castor has low amount of saturated and polyunsaturated fatty acids and this enhance its stability, ... Ethiopia is home to diverse varieties of both edible and non-edible oil plants that have an ample potential for biodiesel production. Consistent with discriminant analysis (DA), the predicted grouping in terms of the two harvest years were correctly acid value and pH value of 6.16 suggest low free fatty acid (FFA) content in the oil. The colored matter is removed by leaching process, and lastly, the oil is subjected to deodorizing step by using the treatment with steam at high temperature and low pressure. It contains about 5-10% ricin by weight. Washington D.C., USA. Seeds were dried about 5-8% moisture contents at 40 °C. Researchers have shown some concern over the use of castor seeds in the preparation of local food condiment and the suitability of the oil quality in diverse industrial applications. Winnowing and 4. There are an astonishing number of industrial applications for castor oil and its derivatives, and new ones are compared with other vegetable oil, because of its unique ability to withstand high and low temperatures. The unique structure of castor oil offers interesting prop-erties, making it appropriate for various industrial applica-tions. Production of Castor Oil and Its Derivatives. of years, demand for castor oil has kept increasing in the international market, assured by more than 700 uses, ranging Production of castor oil by extraction process is economic one. 74, 75 Castor oil can be extracted from castor beans by either mechanical pressing, solvent extraction, or a combination of pressing and extraction. All figure content in this area was uploaded by A. K. Yusuf, All content in this area was uploaded by A. K. Yusuf on Oct 07, 2015, EXTRACTION AND CHARACTERIZATION OF CASTOR SEED, Department of Basic and Applied Sciences, Hassan Usman Katsina Polytechnic, Katsina, Department of Chemistry, Ahmadu Bello University, Zaria, Department of Chemical Engineering, Ahmadu Bello University, Zaria, National Research Institute for Chemical Technology (NARICT), Zaria, was 39.43%. Experiment was conducted under the specified optimum conditions to validate the result predicted by the software. (SBOM) Manufacturer’s Info., Banaskantha, Gujarat, India. Castor oil extraction process is usually achieved using the same method as other vegetable oils, such as groundnut/peanut oil, soybean oil, palm oil, sunflower oil, mustard oil, cottonseed oil, coconut oil and more. The unsaturated fatty acids (UFA) content were 97.5% of the total fatty acids composition. The most common oils consists of palmitic, stearic, oleic, linoleic, and linolenic fatty acids with different ratio based on the nature of seed [35]. These values compare favourably with ASTM standards and general specifications for industrial grade castor oil (WHC, 2012), suggesting that the oil has good industrial potential. In the present study, hybrid bio-support catalyst (BSC) has been prepared for the production of biodiesel from Castor oil. Ricininae. US Patent References: 2616908: Continuous process for solvent extraction of castor oil from castor … Castor was one of the oldest cultivated crops before being abandoned in many countries in The crop is now widely revived as an agricultural solution for all tropical and subtropical regions, addressing Process of extraction may be batch type or continuous. Whitefly and jassids are serious insect pests of castor consecutively for the preceding 3 years in an arid environment. To prove whether glycerol can be one of the hydrogen donors like limonene that is commonly used, the research started by using pure glycerol as the hydrogen donor and as a control to determine the protocol. A process for extracting ricin has been described in a patent. The physicochemical properties fulfill both standards. Castor plant (Ricinus communis L.) is an angiosperm that belongs to the family of Euphorbiaceae. After oil extraction, the impurities in extracted oil will be removed by filter press. The renewable energy sources are either naturally available in excess or can be replenished. Castor oil is known to consist of up to 90% ricinoleic, 4% linoleic, 3% oleic, 1% stearic, and less than 1% linolenic fatty acids. Castor (Ricinus communis L.) is commercially valued for ricinoleic acid and non-edible oil as a lubricant, printing inks, laxative, solvent, biodiesel, etc. Normal hexane was used as solvent for the extraction process. were divided into five, The response of rat erythrocyte fatty acids to 4 fats of widely differing fatty acid compositions was investigated. GCMS spectra show the percentage composition of ricinoleic, linoleic, oleic, stearic, palmitic, and nonanoic acid, as 78.67, 9.62, 6.65, 1.53, 2.19, and 0.08, respectively. 4, No 5, 2015, 1392 – 1404, Received Sep 13, 2015 * Published Oct 2, 2015 *, 1393 A.K. American Oil Chemists Society, Campaign, IL., USA. This can be accomplished by the formation of urea complexes. The properties of oil and biodiesel were calculated using American Standards for Testing Material (ASTM) D6751; formation of biodiesel confirmed by Proton Nuclear Magnetic Resonance (1 H NMR) and Fourier Transform Infrared (FTIR) analysis. oil has the potential to be used in the soap and cosmetics industries. The change in lap shear strength after being placed in cold water, hot water, acid or alkali solutions was tested. Castor oil is unusually polar due to the presence of hydroxyl group at C-12 that accounts for the unique physical and chemical properties such as high viscosity, specific gravity, boiling point and excellent solubility in alcohol (De Lima Da Silva et al., 2009; ... Split ratio of 10.0 was observed at an injection temperature of 260 C. At ion-source temperature of 230 C and total time 49.98 min, mass was recorded. Most adhesives are polymeric adhesives and if made from renewable sources they will have low cost and biodegradability which are of importance. And, the cost-effective castor oil extraction method is by mechanical pressing.
