Refined rice bran oil is a light yellow to brownish yellow oily liquid with a relative density (15/25 ° C) of 0.913 to 0.928. Melting point -5 ~ -10 ° C. The iodine value is 98 to 110. The main components are triglycerides of oleic acid, linoleic acid and palmitic acid. Unrefined butter oil contains 3% to 5.5% unsaponifiable matter. Rice bran oil has a high acid value of about 25% free acid, and contains 1% to 5% of antimony chips, 3% to 9% of antimony wax, 1% to 2% of phospholipids, and a small amount of other impurities mainly oryzanol and sterol. And advanced fatty alcohols.
The rice bran obtained from the rice processing process is obtained by pressing or leaching. Rice bran contains about 18% oil. In addition to serving, it can be used in soap, hardened oil, glycerin, stearic acid, oleic acid, paint resin, etc. It can be eaten after refining. Rice bran oil has a balanced fatty acid composition and is rich in dozens of natural biological active ingredients such as Ve, complex lipid, phospholipid, tocotrienol, squalene, plant sterol (5%), oryzanol (0.5%). The content of unsaturated fatty acids is as high as 80% or more.
Rice bran oil is a unique and precious edible oil. It is a good oil for making nutrient oil, blending oil, frying oil and food ingredients. Rice bran oil main nutrients 1. Oleic acid 40-52% 2. Linoleic acid 29-42% 3. Linolenic acid 0.5-1.8% 4. Palmitic acid 12-18% 5. Stearic acid 1.0-3.0% 6. Plant Sterol 4.5-6.5% 7. Oryzanol 0.1-0.5%
