• 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 is seed oil extracted from castor bean seeds?
  • The percentage of seed oil was measured by the soxhlet extraction method (for seeds from two modes of reproduction). For this purpose, five grams of castor bean seeds were ground (1¨C2 mm particles) and wrapped in a filter paper. Then the samples were transferred to a soxhlet extractor and 250 ml of normal hexane (n-hexane) as the solvent was added.
  • How is seed production performed in castor bean?
  • In this research, seed production in castor bean was performed in two ways: apomixis and open-pollination. Additionally, yield components, agronomic traits, and phytochemical properties were measured to assess variations among different genotypes and compare seed production using the two reproductive modes.
  • Which country produces the most castor oil?
  • India is known as the world leader in castor seed and oil production and leads the international castor oil trade. Castor oil production in this country usually fluctuates between 250,000 and 350,000 tons per year. Approximately 86% of castor seed production in India is concentrated in Gujarat, followed by Andhra Pradesh and Rajasthan.
  • How does asexual reproduction affect castor bean seed production?
  • Sexual reproduction changes excellent traits in later generations, while asexual reproduction by seed (apomixis) transmits superior traits (phytochemical properties and oil content) to the offspring without any change. In this research, seed production in castor bean was performed in two ways: apomixis and open-pollination.
