A simulated moving bed chromatography separator was tested for recovery of γ‐oryzanol from degummed and dewaxed rice bran oil that contained 1.2 to 1.6% γ‐oryzanol. A crude product with 12–15% of γ‐oryzanol was obtained and a 90 to 95% pure product was recovered from the concentrate by crystallization from heptane. With the recycling of the crystallization liquor, an overall γ‐oryzanol recovery of 85 to 90% is feasible and is potentially higher than the recovery in the conventional soapstock‐based process.
