    Refining of high free fatty acid rice bran oil and its quality characteristics. The refined rice bran oil obtained from fresh rice bran (without lipase action) contained about 90% of triacylglycerols whereas, the refined oil from that of high FFA bran oil showed about 10% triacylglycerols. Hence the latter cannot be used as an edible oil, but instead can be used at low levels as a nutraceutical in foods.

    Nov 26, 2009 · Commercial rice bran contains 15–20% of oil and also an endogenous lipase which degrades the oil and produces free fatty acids (FFAs). This study was undertaken to examine the quality of refined oil prepared from crude oil after the action of endogenous lipase in bran.

    Rice bran oil with a high free fatty acid content (FFA) after degumming and dewaxing can be converted into edible quality oil of satisfactory refining characteristics by first adopting the biorefining process to reduce the major portion of the FFA by converting them into neutral glycerides with the aid of 1,3-specific lipase under optimum conditions and later deacidifying the residual FFA of the biorefined oil by alkali neutralization.

    Jul 16, 2019 · Rice bran oil has a similar composition. This vegetable oil is dominated by the high percentage of polyunsaturated fatty acids. Its high omega-6 fatty acid content can give rise to inflammatory markers and increase the risk of both heart disease and cancer. Hence, this oil may not be suitable for individuals with low omega-3 fatty acid intake.

    The much lower linolenic acid content of rice bran oil makes it more stable to oxidation than soy oil. The quality characteristics of properly refined rice bran oil include a maximum free fatty acid levels (as oleic acid) of 0.1%, a maximum peroxide value of 1.0 meq/kg, 0.05% moisture, an iodine value of 99–108, saponification value of 180-195, and a Lovibond color value of 3.5R.

    Mar 16, 2019 · Stabilisation of Rice Bran: Besides having generic steps of oil extraction and refining, the heart of rice bran oil processing lies in the stabilisation of the rice bran. As aforesaid, rice bran contains lipase that starts hydrolysing the triglycerides immediately after removal of bran from the grain and results in a prolific increase in the free fatty acids.
