Abstract:

In search of solution to the harmful ecological problems due to toxicity and non-biodegradability posed by conventional transformer insulation oil (mineral oil), the production of transformer oil from castor seed oil (vegetable oil) was carried out. The oil was extracted using N-hexane and was refined. The transformer oil was produced by trans-esterification and was characterized using American Society for Testing Material (ASTM) standard test. The solvent employed gave good yield of oil from the seeds. The results of characterization show that the density 0.987 (g ml<sup>–1</sup>), viscosity7

Extraction of castor oil is important in determination of the quality of castor oil extracted. The quality of castor oil being extracted has to meet the ASTM standard that has been produced. The way of extraction can be either mechanical extraction or chemical extraction that is practically used in the industry which give the highest yield of oil extracted. Castor oil is mainly composed of ricinoleic acid in high concentration. It is a unique vegetable oil that contains high content of fatty hydroxyacid.

Castor (Ricinus communis L.) seeds produce abundant ricinoleic acid during seed maturation, which is important for plant development and human demands. Ricinoleic acid, as a unique hydroxy fatty acid (HFA), possesses a distinct bond structure that could be used as a substitute for fossil fuels. Here, we identified all homologous genes related to glycolysis, hydroxy fatty acid biosynthesis, and triacylglycerol (TAG) accumulation in castor seeds. Furthermore, we investigated their expression patterns globally during five seed development stages. We characterized a total of 66 genes involved in t

However, castor oil actually can be used to produce many valuable products such as chemicals, paint, and cosmetics due to its unique characteristic which contains a high percentage of ricinoleic acid that helps in producing many valuable products.

Abstract:

This report describes biomass production and compositional changes of developing castor seeds in response to change in the nitrogen resource (glutamine) of the medium. During the early developmental period (24-36 days after pollination), oil was found to initially accumulate in the developing seeds. Carbohydrates and oil were inversely related after glutamine provision (35 mM, in the culture medium). [U-14C] sucrose labeling was used to investigate the effect of metabolic fluxes among different storage materials. Addition of glutamine led to a 7% increase of labeling in lipids and an inverse d

Abstract:

The increasing demand for energy and the depletion of fossil fuel resources has led to the search for an alternative energy source. The search for such alternative fuel sources has oriented biodiesel synthesis as the ultimate alternative energy resource of the future. The purpose of this study was to produce castor oil and optimize biodiesel production using full factorial central composite design (CCD) through the response surface methodology (RSM) approach. The castor oil was extracted using a mechanical press, and free fatty acids were reduced with acid esterification and biodiesel produced

The aim of this work was to improve the mechanical properties of polylactic acid (PLA) by natural oil polyol. Castor oil is natural oil polyol used for this work. It was directly extracted from castor seed and without chemical modification. The contents of castor oil were varied from 0 to 10 wt%. The effect of castor oil content on mechanical properties of PLA were evaluated by tensile and impact testings. Differential scanning calorimetry (DSC) and morphology analysis were used for explanation of the result. The result showed that the elongation at break and impact strength of PLA /10 wt% cas

Abstract:

Castor is an important oilseed cash crop. Castor oil obtained from castor seed is non-edible, but is of great industrial importance. India is the largest castor growing country in the world. Gujarat state has highest area and production of castor. In Rajasthan, Sirohi district stands first in terms of area and production of castor. Therefore, a study was undertaken to assess the level of knowledge of respondents about castor production of Sirohi district. The study was conducted in 5 blocks. Further, 100 farmers were selected randomly from 10 villages. The findings of this study revealed that

Castor bean (Ricinus communis L.) is cultivated mainly for biodiesel production because of its oil-rich seeds; it is assumed to be an anemophylous species. But pollination deficit can lead to low productivity often attributed to other reasons. In this paper, we investigated pollination requirements, pollination mechanism, occurrence of pollination deficit, and the role of biotic pollinators in a large commercial plantation of castor bean. Our results show that R. communis bears a mixed breeding system favoring selfing by geitonogamy, although the wind promotes mostly outcrossing. We also found

Nanoemulsions are significant for cosmetic products intended for skin care and for health products due to the reduced size (range 20 to 500 nm) of the globules, which avoids processes of instability. They present transparency, fluidity, wettability, and spreadability; increase skin penetration; and have good sensation. The main instability mechanism of nanoemulsions is called Ostwald ripening, responsible for increasing the average diameter of emulsion globules.

Energy consumption is on the rise due to rapid technological progress and a higher standard of living. The use of alternative energy resources is essential to meet the rising energy demand and mitigate the carbon emissions caused due to use of fossil-based fuels. Biodiesel produced from non-edible oils such as castor seed oil (CO) can be used in diesel engines to replace fossil diesel. However, the quality and yields for CO biodiesel is low due to the presence of ricinolic acid C18:1OH (79%). In this study, two-stage conversion techniques were used to improve the yields and properties of CO bi
