2. Introduction of Rice Bran Oil It is a vegetable oil extracted from the outer layer (bran) of the rice grain. It has been used for cooking in Asian countries, particularly in Japan, India, and China, for centuries. Here are some key points about rice bran oil: Nutritional ProfileRich in Nutrients: - C ontains vitamins E and K, and is a good source of antioxidants. Healthy Fats: High in monounsaturated and polyunsaturated fats, and low in saturated fats. Gamma- Oryzanol : A unique compound found in rice bran oil, known for its antioxidant properties. Health Benefits :- Heart Health : The balanced fatty acid profile can help lower cholesterol levels and improve heart health. Skin Health : Often used in cosmetics for its moisturizing and anti-aging properties. An ti -Inflammatory : Gamma- oryzanol and other compounds have anti-inflammatory effects.

En vironmental and Economic AspectsBy -Product Utilization : Using the bran, a by-product of rice milling, adds value and reduces waste.Economic Impact: Supports economies in rice-producing countries by providing an additional revenue stream.

4. Physical Refined Rice Bran Oil Rice Bran Oil is nutritious edible oil produce from the oily layer of brown rice which is separated as rice bran while polishing white rice. The Company is using Physical Refining Process to refine this health friendly cooking oil so as to preserve the nutrients which would Otherwise be lost due to the use of chemicals

5. Manufacturing Process of Rice Bran Oil SOLVENT EXTRACTION PROCESS Kneading Forming pallets Sieving & cooking Rice Bran Hexane Spray on Pallets (Oil +hexane) Micela Separate Hexane Raw Rice Bran Oil

6. REFINING PROCESS Of RBO Crude oil/ Raw RBO Wash with water/Wash Oil Drying Degumming (Add Enzyme) Bleaching De – Waxing and Pre - Bleaching Wintrization of oil Bleaching (Final) Deodrization Final Refine Rice Bran Oil

7. Continue… 1) Solvent Extraction :- RBO produce from Solven ( normally hexane) extraction is preferred as cooking oil. The solvent oil mixture is called miscella . Separation of oil and hexane by distillation stages. 2) Degumming :- It involves the removal of Phospholipids & Lipoprotiens through hydration with citric or phosphoric acid. Crude oil contains upto 1200ppm of phosphorus equivalent of 3% phospholipids. After degumming, this level reduce to 20 ±50 ppm. For physical refining, P level lower than this. 3) Neutralization :- Free Fatty Acids are removed by caustic soda ( NaOH ) in the Neutralizationprocess . 4) Bleaching :- To remove pigments (chlorophyll & carotenoids) of RBO by absorption on activated carbon or bleaching earth. These are remove Polycystic aromatic hydrocarbon and trace p hospholipids , metal, soap .

8. Continue.... 5) De-Waxing & Winterize:- Dewaxing is total crystallization time goes below 20 hrs. If proper crystal growth doesn’t taken, then more loses occurs in dewaxing and filtration slow down. So the dewaxing and winterization steps done by maintaining the oil at a low temperature to solidify waxes are separated as waste products. Deodorization:- Final step of refining process of RBO to produce oil with bland flavor and good shelf life. This requires to remove the oxidation products responsible for off flavor. It is achieved by high temperature. Between 170degree C & 250 degree C under reduced pressure. Deodorize distillate is useful source of sterile & tocopherols, neutral oil, fatty acids, Unsponifiable matters.
