Rice bran oil was blended with double fractionated palm olein (DF palm olein) to examine the cooking performance of blended oil. A blended oil made with 80% or higher rice bran oil and 20% or less DF palm olein passed the cold test, and had a cloud point of -3 deg C. Blending of DF palm olein to rice bran oil lowered the smoke point, refractive index, and absorbancies at 232 and 268 nm of rice bran oil. Dielectric constant of oils was not affected by blending during heating. Blending of DF palm olein, however, increased the acids formation in rice bran oil, whereas it retarded polymer formation
