Unsaturated fatty acids: (Neutral) Monounsaturated (MUFA) Oleic acid (Omega 9) Concentrated source of energy Unsaturated fatty acids: (Positive) Polyunsaturated (PUFA) Important Biological Role Major part of cell membrane and skin layers.
Rice Bran: Some Fundamentals Rice bran is composed of the aleurone layer of the rice kernel and some part of the endosperm and germ, which are rich sources of proteins, lipids, vitamins, and trace minerals Rice bran oil and unsaponifiable lipid content is high compared with other grains Unrefined rice bran oil consists of 20% saturated, 40% monounsaturated, and 40% polyunsaturated fatty acids and contains tocotrienols, γ-oryzanol, and β-sitosterol. Rice bran and its oil contain large concentrations of several compounds that could potentially prevent chronic diseases such as coronary heart disease and cancer
Rice Bran: Some Fundamentals Their initial studies with rice bran focused on stabilizing against lipid degradation that leads to flavor problems Rice bran contains: - high levels of both tocopherols and tocotrienols, - vitamin E and act as antioxidants in the body - high levels of a mixture of compounds referred to collectively as oryzanol were identified within rice bran Oryzanol: complex compounds that can act as an antioxidant, improving solubility in cell membranes and potentially lowering cholesterol by competitive inhibition of absorption and synthesis Methods of separating the individual components of the oryzanol mixture have come about, leading to the identification of 3 major fractions of oryzanol:cycloartenyl ferulate, 24-methylene cycloartanyl ferulate,campesteryl ferulate

Gives better taste & aroma to food items. Helps to increase HDL level. Anticancer & antithromic properties due to Vitamin E. Reduces total cholesterol.
Rice Bran Oil (RBO) & Cholesterol Reduction The antioxidant activities of four of the vitamin E and three oryzanol components purified from rice bran were investigated in a chemical model of cholesterol oxidation All components exhibited significant antioxidant capacity in the inhibition of cholesterol oxidation! All three oryzanol components were higher than any of the four vitamin E components In the past, human consumption of rice bran has been limited, primarily because of the rapid onset of rancidity in rice bran, but methods to stabilize rice bran and to extract its oils have been developed Interest in rice bran grew from the determination that the inclusion of oat bran in the diet lowers serum cholesterol Rice bran contains less total dietary fiber and less soluble fiber than oat bran Components found in rice bran which could be responsible for its cholesterollowering effects: The fiber that is present The Fatty acid composition Or the Unsaponifiables present Oryzanol, phytosterols PBRC (campesterol 2005 and β-sitosterol)
Rice Bran Oil (RBO) & Cholesterol Reduction Evidence from 2 well-controlled studies at Pennington Biomedical Research Center confirms that it is the rice bran oil (RBO), and not the fiber, that lowers blood lipids in men and women with borderline high total cholesterol Although RBO does contain about 20% saturated fatty acids and approximately equal amounts of oleic and linoleic fatty acids, its cholesterol lowering ability is due to its unsaponifiable components more so than by its fatty acid composition In a recent study, by matching the fatty acids of the rice bran oil with a control oil blend, it was shown that the effect of RBO on serum cholesterol concentrations is due to the unsaponifiables present in it and not to its fatty acid profile It is believed that RBO containing these compounds could become an important functional food with cardiovascular health benefits http://www.agctr.lsu.edu/communications/louisianaagriculture/agmag/45_4_articles/ricebran.asp http://www.nutrition.org/cgi/content/full/128/5/865 http://www.ajcn.org/cgi/content/full/81/1/64

International Lipid Guidelines Association WHO Lipid Guidelines All individuals should be strongly encouraged to reduce total fat and saturated fat intake (1+, A). Total fat intake should be reduced to about 30% of calories, saturated fat intake should be limited to less than 10% of calories and trans-fatty acids eliminated. Most dietary fat should be polyunsaturated (up to 10% of calories) or monounsaturated (10 15% of calories). (1+, A) ESC/EAS To improve plasma lipid levels, saturated fat intake should be lower than 10% of the total caloric intake. The optimal intake of SFAs should be further reduced (,7% of energy) in the presence of hypercholesterolaemia. The intake of n-6 PUFAs should be limited to,10% of the energy intake, both to minimize the risk of lipid peroxidation of plasma lipoproteins and to avoid any clinically relevant HDL-C decrease.supplementation with pharmacological doses of n-3 fatty acids (.2 3 g/day) reduces TG levels, but a higher dosage may increase LDL-C; not enough data are available to make a recommendation regarding the optimal n-3/n-6 fatty acid ratio. The cholesterol intake in the diet should ideally be,300 mg/day. Limited consumption of foods made with processed sources of trans fats provides the most effective means of reducing intake of trans fats below 1% of energy. TLC/ ATP III /NCEP Nutrient Recommended intake: Saturated fat* <7% of total calories, Polyunsaturated fat Up to 10% of total calories, Monounsaturated fat Up to 20% total calories, Total fat 25% 35% of total calories,cholesterol <200 mg./day NICE Advise people at high risk of or with CVD to eat a diet in which total fat intake is 30% or less of total energy intake, saturated fats are 7% or less of total energy intake, intake of dietary cholesterol is less than 300 mg/day and where possible saturated fats are replaced by monounsaturated and polyunsaturated fats.

Why is PUFA required from Dietary Source Daily Caloric requirement for sedentary man = 2320 kcal Calories coming from fat (25%) = 576 kcal Grams of fat consumed (g) per day = 64 g (approx. 60g) Grams of PUFA consumed (g) per day = 25g 60 g of Fat Invisible Fat (35g) PUFA = 14g i.e. 40% PUFA Visible Fat (25g) Remaining deficit 11g PUFA i.e. 44% PUFA Hence, the oil consumed should have equivalent amount of MUFA & PUFA
Fate of Edible Oil Frying Conditions: Food is subjected to High Temperature with humid conditions and atmospheric oxygen Increased Oxidation Increased free radical generation + Secondary products generation Hence, it becomes important to prevent deterioration of oils during Frying
Preventing Degradation of Oil On Shelf: Free radicals caused due to oxygen around the product affect the freshness of oils. Thus, oil starts deteriorating. During Cooking: Free radicals formation accelerates during heating at high temperatures. These lead to formation of harmful secondary oxidation products. In vivo: Free radicals are produced constantly in body due to metabolism. They cause cell damage. Source: 1. Madamanchi, Nageswara R., Aleksandr Vendrov, and Marschall S. Runge.
