Abstract:

The world’s energy matrix can be diversified with biodiesel from castor and jatropha oil. Hence, the objective of this study was to assess a conversion path for the valorization of castor and jatropha seeds. The results showed the maximum extraction of castor oil at 90 °C, 2 rpm, and 6 mm nozzle, achieving a yield of 36.97% and for jatropha oil at 100 °C, 1.5 rpm, and 10 mm nozzle, achieving a yield of 20.11%. The acid value and cloud point of castor and jatropha oil were 0.797 and 23.44 mg KOH/g, 10±1 °C and 12±0.55 °C, respectively; while the pour point was -3 °C for both. The acid value and

Abstract:

The purpose of the research is to increase the efficiency of hulling castor bean seeds and separating its crushed seeds in the gen-eral technological process of material processing. In the technology of castor bean processing, an important place is occupied by the operation of hulling and separating its crushed beans, which should prevent toxic substances such as ricin, ricinin and allergen from entering the final product of processing. When applying electrophysical methods of influencing castor bean seeds, it is neces-sary to have an understanding of the electrical properties of the component

Abstract:

Environment and storage time influence stored seed quality, especially for oilseeds such as castor beans because they have a high lipid content and are more prone to deterioration. This study evaluated the physiological quality of seeds from three castor bean genotypes stored at 10 and 20°C for 300 days. The experimental design was completely randomized, with 4 replications, in a 2 x 6 (2 temperatures x 6 storage periods) split-plot design. The seeds were placed in low-density polypropylene bags and stored in climatic chambers at 10 and 20°C, in which the temperature and relative humidity were

Abstract:

Castor (Ricinus communis) seeds are rich in a type of hydroxy fatty acid called ricinoleic acid, which is in high demand for the production of plant-based plastics, lubricants, and hydraulic oils. However, the high content of ricin, a toxic protein, in these seeds has restricted further expansion in the area of castor cultivation. Therefore, the development of ricin-free castor is needed. Genome editing technology, although successfully applied in several plant species, is still in the developing stages in castor and awaits the identification of an endogenous U6 promoter with robust function.

Abstract:

The aim of the study is to investigate the physicomechanical properties of castor fruits and seeds (Ricinus communis L.) to substantiate the design and technological parameters of machines and equipment intended for their extraction and cleaning. Laboratory research on specialized equipment was conducted to determine the primary physical-mechanical properties of castor bean fruits and their components (segments, seeds, and capsule particles). These properties include geometric dimensions (length L and width B), mass M, bulk ρb and true ρd densities, angle of repose φ, friction coefficients (sl

Abstract:

Seeds of castor (Ricinus communis) are enriched in oil with high levels of the industrially valuable fatty acid ricinoleic acid (18:1OH), but production of this plant is limited because of the cooccurrence of the ricin toxin in its seeds. Lesquerella (Physaria fendleri) is being developed as an alternative industrial oilseed because its seeds accumulate lesquerolic acid (20:1OH), an elongated form of 18:1OH in seed oil which lacks toxins. Synthesis of 20:1OH is through elongation of 18:1OH by a lesquerella elongase, PfKCS18. Oleic acid (18:1) is the substrate for 18:1OH synthesis, but it is al

Abstract:

The castor (Ricinus communis L.) is an oilseed plant whose main features are its drought resistance, and its adaptation to eroded, polluted, and low fertility soils. Its oil has a great demand in the industrial sector and it has recently attracted considerable interest for its use in the production of biodiesel and jet fuel. In this study, morphological, physical and chemical characterizations were performed to ascertain the quality of wild (VQ-1) and under cultivation (VQ-7) oil castor seeds. The results showed that there are differences in the morphological and physicochemical characteristic

Abstract: Ricinus communis is a shrub of the family Euphorbiaceae popularly known in Brazil as “mamona” or “carrapateira”. It is an oleaginous plant whose seeds have been used mainly in biodiesel production. Plant seed oil can be extracted mechanically or using solvents, generating castor bean cake and castor bean meal as by-products, respectively. Accidental ingestion of these by-products can cause poisoning in animals and humans, characterized by digestive signs resulting from the presence of a toxalbumin called ricin. Seed toxicity varies among animal species; in horses, the lethal dose of

Ricinoleic acid is a hydroxy fatty acid (HFA) which is accumulated in seeds as Triacylglycerols (TAGs). Castor oil has a very high demand all over the world and India is the country who majorly fulfils world’s demand.

Castor gourd is produced by crushing castor seeds in an expeller to extract the oil. Castor gourd is one of the most versatile natural manures. It is a truly organic manure that improves soil fertility without causing damage or rot. Castor flour contains Ricinus communis, a substance that is toxic to humans, animals and insects. One of the major toxic proteins is “ricin”, which has been reported to cause abdominal pain, vomiting, diarrhea, dehydration, depression and death.

These functional groups in castor seeds were chemically modified individually to determine their contribution to the adsorption of ionic dyes. The dyes used were remazol red B, procino yellow, fast green FCF, brilliant cresyl blue, methylene blue, neutral red, red-141. It was found that hydroxyl group inhibited the adsorption of anionic dyes but it was major functional group in the adsorption of cationic dyes, hydroxyl
