Frying performance of processed rice bran oils

چکیده
509 The rice bran oil (RBO) contains high levels of phytosterols, gammaoryzanol, tocotrienols as well as tocopherols and it extends the shelf-life of snack foods. The high oxidative stability of RBO makes it preferred oil for frying and baking applications. The saturated, monounsaturated and polyunsaturated fatty acids in RBO are in the ratio of approximately 1:2.2:1.5 and the major fatty acid compositions are not influenced by storage temperature, although linolenic acid level decrease by approximately 50% during storage. The oils are stabilized by addition of approximately 2-5% by weight of RBO, which is processed to retain unsaponifiable matter. The stabilized oil may be useful as a spray oil for crackers, nuts, chips and other snack foods. Blending of one oil with another oil (especially RBO) has also been found to improve the stability of the blend during frying and storage. The improved frying stability of low linolenic acid soybean oil compared to normal soybean oil has also been reported. RBO is a nutritionally superior oil compared to other common vegetable oils. The oil has minor components such as oryzanol, phytosterols, tocotrienols, tocopherols and squalene which show cholesterol-lowering and skin-improving effects in addition to antioxidant effects. Presence of oryzanol and higher amounts of unsaponifiable matter (such as phytosterols) are unique to RBO. Produced in India, RBO is available in two Oil/Fats

Effect of Deep-Fat Frying on Physicochemical Properties of Rice Bran Oil Blends
Rice bran oil, non conventional oil was blended with six traditional oils in the ratio of 70:30 and 80:20 for the enhancement of its market acceptability and awareness in consumers regarding its use in cooking. Effect of deep-fat frying on these blends was studied by assessing the changes in percent fat absorption and physicochemical properties during repeated frying process (three times). The ...

Abstract—The aim of this study was to determine the effect of oils on chemical, physical, and sensory properties of deep-fried dough stick. Five kinds of vegetable oil which were used for addition and frying consist of: palm oil, soybean oil, sunflower oil, rice bran oil, and canola oil. The results of this study showed that using different kinds of oil made significant difference in the qualit...
متن کاملFrying Stability Evaluation of Rice Bran Oil Blended with Soybean, Mustard and Palm Olein Oils
Refined rice bran oil (RBO) was blended with PUFA rich Soybean oil (SBO), MUFA rich Mustard oil (MO) and SFA rich Palm Olein oil (POO) to make a blend that had sufficient amount of Omega-3 fatty acid by mixing two or more oils in the ratio of 60:40 and 60:20:20 respectively. RBO and its blends were subjected to deep fat frying of potato chips at 180±10C for 24h. Oil samples were withdrawn after...
متن کاملChanges of Major Antioxidant Compounds and Radical Scavenging Activity of Palm Oil and Rice Bran Oil during Deep-Frying.
Changes in antioxidant properties and degradation of bioactives in palm oil (PO) and rice bran oil (RBO) during deep-frying were investigated. The alpha (α)-tocopherol, gamma (γ)-tocotrienol and γ-oryzanol contents of the deep-fried oils were monitored using high performance liquid chromatography, and antioxidant activity was determined using 2-diphenyl-1-picryl hydrazyl (DPPH) radical scavengi...
