This document summarizes a study on the effect of refining processes on the cellular antioxidant activity (CAA) of rice bran oil. The study found that deacidification, which removes free fatty acids, significantly reduced the CAA value of rice bran oil samples. Higher concentrations of rice bran oil extracts exhibited higher CAA values. The CAA value was also correlated with minor components like sterols and oryzanols that are removed during refining. The results indicate refining processes should be optimized to retain beneficial minor components that contribute to rice bran oil's antioxidant properties.
It contains the manufacture of oil, various refining processes such as degumming, alkalization,etc and hydrogenation of oil. Solvent extraction is also briefly explained.
Vegetable oils, or vegetable fats, are oils extracted from seeds, or less often, from other parts of fruits. Like animal fats, vegetable fats are mixtures of triglycerides. Soybean oil, sunflower oil, rapeseed oil are examples of fats from seeds. Olive oil and palm oil are examples of fats from other parts of fruits. In common usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible.

In refining process, physical and chemical processes are combined to remove undesirable natural as well as environmental-related components from the crude oil.
Methods for recovery of γ- Oryzanol from Rice bran oil refiningOmkarJoshi81
Rice is major source of food all over world. Rice bran coat is removed from white rice for consumption purpose. Rice bran contains 15-20% of lipid, which on further processing like extraction becomes as Rice bran oil.
Rice bran oil is normally obtained from the bran composite of rice that is removed during the milling process of brown rice to produce white rice, although some extraction processes were developed that occur during the milling process. Commercial rice milling practiced in most of the world does not separate the germ from the bran efficiently, and in many cases unable to separate hull from bran. Thus, what is called rice bran usually contains the germ and parts of the hull and endosperm also.

Palm Oil, Palm Kernel Oil Process - Fractions, Derivatives and Product UsesGreenPalm
One of our previous infographics looked at an overview of the complexity in the palm oil / palm kernel oil supply chain. RSPO (Roundtable on Sustainable Palm Oil) certified oil still remains a market niche (16% of total palm oil production now RSPO certified); keeping physical oil separated from non certified oil can be very difficult and impossible depending on where you are based and the types of process and products used. If the world just used crude palm oil, tracing physical sustainable palm oil would be simpler.
We now delve a little deeper into the supply chain, identifying the various processes along the supply chain. Included are examples of product applications with a key that describes the various products and processes e.g Fractionation, Hydrogenation, distillation, IE Palm Stearin, RBD Palm Kernel Stearin, Emulsifier etc.
The product examples we provide do not cover all individual products that palm or palm kernel oil are used in. All main refinery processes are covered; however further blending and manufacturing processes do take place passed what is shown in this graphic.

Jatropha curcas oil (JCO) and karanja oil have been identified for the comparative study of production of renewable energy sources i.e. biodiesel as well as physico-chemical properties of biodiesel for its potentiality. Enzyme Novozyme 435 (Candida antarctica) is used as biocatalyst (8%) for the conversion in both the cases with 5:1 molar ratio of alcohol to oil for 8 hours with mixing intensity of 600 rpm at 550C. JCO shows higher conversion efficiency at these parameters than karanja oil. Biodiesels obtained from JCO and karanja oil are analysed based on physico-chemical properties like specific gravity, kinematic viscosity, density, calorific value, cetane number, flash point, cloud point and acid number. With regard to specific gravity, kinematic viscosity, density, calorific value and cetane number, the JCO biodiesel shows higher values than karanja biodiesel whereas flash point and cloud point of karanja biodiesel are higher than JCO biodiesel. With respect to the compositional analysis, JCO biodiesel contains 95.67% methyl ester but karanja biodiesel contains 92.57% methyl ester. Apart from this, triglycerides (TG), diglycerides (DG) and monoglycerides (MG) content of JCO and karanja oil biodiesel are 1.68%, 1.08%, 2.68% and 1.89%, 2.75% and 3.69% respectively.

Pupal oil - An alternative feedstock for biodiesel productionmithilasrim
This presentation is about silkworm pupal oil and this is my PhD seminar presentation and it will help to know about value addition to silkworm pupal oil.
Depleting nature of nonrenewable energy sources and continuous environmental tribulations make the mankind to think differently regarding alternative renewable energy sources. In this regard, present research investigation contributes biodiesel from canola oil deodorizer distillate (CODD) using Lipase AY Amano 30 (Candida rugosa) and Novozyme 40013 (Candida antarctica) in the presence of methanol. Initially the neutral glycerides present in CODD were hydrolysed using lipase Amano AY 30 in the presence of water. The hydrolysed CODD was then esterified with methanol using non-specific immobilized enzyme NS 40013 for the production of biodiesel. The characteristics of final product were compared with diesel fuel and it showed good results. This bioprocess technology using biohydrolysis and bioesterification is a novel technology for biodiesel production from cheap raw materials like CODD.

Summary & Perspectives
Attention should be given to minor constituents
• RBO contains sufficient amounts of endogenous minor constituents .
• Minor constituents have a vital role in providing anti-oxidant properties.
Refining methods for oils should be optimized
• Edible oil needs precise and appropriate processing.
• Refining methods should be optimized to retain oryzanol and sterol.
