  • How much Oryzanol is retained in crude oil?
  • Irrespective of the strength of alkali (12 to 20° Be studied), retention of oryzanol in the refined RBO was only 5.4–17.2% for crude oil, 5.9–15.0% for degummed oil, and 7.0 to 9.7% for degummed and dewaxed oil.
  • How much Oryzanol is removed from crude oil?
  • Degumming and dewaxing of crude RBO removed only 1.1 and 5.9% of oryzanol while the alkali treatment removed 93.0 to 94.6% of oryzanol from the original crude oil.
  • What percentage of Oryzanol is lost during the chemical refining process?
  • Thus, the oryzanol, which is lost during the chemical refining process, has been carried into the soapstock. The content of oryzanol of the commercial RBO, soapstock, acid oil, and deodorizer distillate were in the range: 1.7–2.1, 6.3–6.9, 3.3–7.4, and 0.79%, respectively.
  • How much -Oryzanol is in RBO?
  • Therefore, the concentration of γ-oryzanol in refined RBO is merely 2% of its initial value in crude RBO ( Pestana et al., 2008 ).
  • What is the oryzanol composition of crude oil and soapstock?
  • The oryzanol composition of crude oil and soapstock as determined by high-performance liquid chromatography indicated 24-methylene cycloartanyl ferulate (30–38%) and campesteryl ferulate (24.4–26.9%) as the major ferulates.
  • What are the phytochemical concentrations of -oryzanol?
  • The highest phytochemical concentrations were found in the precipitated soap for γ-oryzanol (14.2 mg g −1, representing 95.3% of total γ-oryzanol in crude RBO), and in the deodorisation distillate for tocopherols (576 mg 100 g −1, representing 6.7% of total tocopherols in crude RBO).
