TL;DR: In this paper, a two-stage formulation process (esterfication followed by transesterification) to convert industrial grade rice bran oil into biodiesel, physio-chemical characterization of biodiesel and run a small capacity, single cylinder, direct injection diesel engine on biodiesel.
Abstract: Biodiesel is gaining momentum in India and rice bran oil (RBO) could be utilized as a possible source of biodiesel. Since industrial grade RBO has high FFA content, base catalyzed transesterification process is not an appropriate method for production of biodiesel. This study reports two-stage formulation process (esterfication followed by transesterification) to convert industrial grade RBO into biodiesel, physio-chemical characterization of biodiesel and run a small capacity, single cylinder, direct injection diesel engine on biodiesel .The performance and emission results of biodiesel are compared with diesel.

TL;DR: In this article, a rose flower cold-made soup and a manufacturing method for making soap is described, which is mainly characterized in that main raw materials comprise rose flower olive dipped oil, coconut oil, rice bran oil, rose flower hydrosol, NaOH and rose flower essence oil.
Abstract: The invention discloses rose flower cold-made handmade soup and a manufacturing method thereof. The soap is mainly characterized in that main raw materials comprise rose flower olive dipped oil, coconut oil, rice bran oil, rose flower hydrosol, NaOH and rose flower essence oil. The method includes 1) mixing the rose flower olive dipped oil, the coconut oil, the rice bran oil, and the like according to a ratio and heating to 40-50 DEG C, 2) adding the froze rose flower hydrosol into the NaOH, fully mixing, and cooling to 40-50 DEG C, 3) slowly adding the NaOH into the mixed oil until the NaOH and the oil are fully mixed, 4) adding the rose flower essence oil or rose flower essence and fully stirring, 5) adding a small amount of fresh or dry rose flowers and fully stirring, and 6) moulding by reserving a mould. The soap has functions of whitening skin, fading speckles, improving dry, coarse, dark, gloomy, oily and acne skin, and the like. Fragrance of rose flowers can slowly eliminate anxiety and depression, boost mood, restore mental equilibrium and relieve pressure. The soap is suitable for persons with various skin types. The soap is a purely natural product and is free of any harm to human bodies.

TL;DR: The compositional characteristics and oxidative stability of rice bran oil were determined by observing the formation of oxidative products and alteration in chemical composition of oils during microwave or oven heating and the present results will be useful to oil seed processing mills in refining of rice Bran oil for economic feasibility and better marketability.
Abstract: The compositional characteristics and oxidative stability of rice bran oil were determined by observing the formation of oxidative products and alteration in chemical composition of oils during microwave or oven heating. The values of oxidative indicators such as free acidity, peroxide, p-anisidine, total oxidation, thiobarbituric acid and color values, increased faster in refined oils compared to crude ones during heating. In gas chromatography analysis, the percentages of total saturated, monounsaturated and polyunsaturated fatty acids in the studied oils such as lab extracted crude rice bran oil, lab extracted and refined rice bran oil, crude rice bran oil from commercial mill and refined rice bran oil from commercial mill were: 23.07 to 23.56, 41.15 to 42.38 and 34.38 to 35.88, respectively. The heating caused the reduction of polyunsaturated fatty acids content with increasing saturated fatty acids content, and these changes were greater in refined rice bran oil indicating extensive lipid oxidation occurred in refined oil. The change in triacylglycerol species content as determined by High-performance liquid chromatography, was lower in crude oil; the higher stability of these species in crude oil could have contribution to reduce oxidation. During thermal treatment, the generation of hydroperoxides, their degradation and formation of secondary oxidative products evaluated by Fourier-transform infrared spectroscopy, were lower in crude oils. However, the rate of formation of oxidative products in lab prepared samples was lower compared to that in the samples collected from commercial mill. Under extreme thermal condition, the order of oxidative stability: lab extracted crude rice bran oil > crude rice bran oil from commercial mill>lab extracted and refined rice bran oil > refined rice bran oil from commercial mill. The present results will be useful to oil seed processing mills in refining of rice bran oil for economic feasibility and better marketability.

TL;DR: In this article, a three phase partitioning (TPP) technique was used to extract oil, protein and polysaccharides simultaneously from rice bran, and the results were similar to those obtained by other methods.
Abstract: Three phase partitioning (TPP) technique was used to extract oil, protein and polysaccharides simultaneously from rice bran. The fatty acid composition of rice bran oil (RBO) and structure of rice bran protein (RBP) and rice bran polysaccharides (RBPS) were analyzed. Under the optimal conditions of (NH4)2SO4 concentration 28% (w/v), slurry to t-butanol ratio 1:1.1 (v/v), pH 5.10, extraction temperature 40 °C and extraction time 1 h, the highest extraction yields of RBO, RBP and RBPS were 17.28%, 6.81% and 2.09%, respectively. The fatty acid composition of RBO was analyzed by GC, the structure of RBP was analyzed by FTIR and SDS-PAGE, and the structure of RBPS was analyzed by FTIR. The results were similar to those obtained by other methods. Therefore, TPP can be used as an effective technology for simultaneous extraction of oil, protein and polysaccharide from rice bran.
