TL;DR: Different types of vegetable oils have their own specific advantages and biological activities, and appropriate vegetable oils can be selected to meet individual needs accordingly.
Abstract: Background With a continuous increase in population and economic development, the demand for high quality seed oils keeps increasing in China. In the last decades, many minor edible oils become increasing and popular. Scope and approach In this review, the chemical composition and nutritional properties of minor edible oils, including flaxseed oil, corn oil, rice bran oil, camellia oil, safflower oil, almond oil, grape seed oil, walnut oil, perilla seed oil, pumpkin seed oil, evening primrose oil, Eucommia ulmoides Oliver seed oil, penoy seed oil, sea buckthorn seed oil, Acer truncatum Bunge seed oil, Torreya grandis seed oil and tomato seed oil, were summarized. The characteristic chemical compositions of these 17 kinds of minor edible oils were analyzed from fatty acid composition, phytosterols, tocopherols, total phenolic content, squalene and β-carotene contents. Key findings and conclusions Different types of vegetable oils have their own specific advantages and biological activities, and appropriate vegetable oils can be selected to meet individual needs accordingly. For example, Acer truncatum Bunge seed oil contains 5.52% nervonic acid (C24:1) that can promote the repair and regeneration of nerve cells and tissues damaged, while corn oil and rice bran oil have higher contents of campesterol and total phytosterol and might be therefore better choices for patients with high cholesterol and cardiovascular diseases. This review could benefit comprehensive understanding nutritional values of minor vegetable oils and future researches on nutrition and product development.

TL;DR: A decrease of oxidative stability of about 30% was found in all the oils after 12 months of storage and the PV of 10, determined in the thermostat and Rancimat tests, were achieved at the latest in corn oil and the fastest in rice bran oil.
Abstract: The aim of the study was to examine and compare oxidative stability of refined (peanut, corn, rice bran, grapeseed, and rapeseed) oils. The oils were subject a Schaal Oven Test (temperature 63 ± 1 °C) and a Rancimat test (temperature 120 °C) and their stability was compared at the 1st and 12th month of storage. Changes in the peroxide (PV) and anisidine (AnV) values in the thermostat test were the fastest in rapeseed oil and grapeseed oil. The best quality was preserved by peanut and corn oils both in the first and the twelfth month of storage. The induction times for the rice bran, corn, peanut, and rapeseed oils were similar from 4.77 h to 5.02 h in the first month and from 3.22 h to 3.77 h in the twelfth month. The shortest induction times were determined for grapeseed oil: 2.4 h and 1.6 h, respectively. A decrease of oxidative stability of about 30% was found in all the oils after 12 months of storage. The PV of 10, determined in the thermostat and Rancimat tests, were achieved at the latest in corn oil and the fastest in rice bran oil.

Abstract: This manuscript presents the impact of addition of antioxidant additives to rice bran biodiesel blend on the performance and emission characteristics of compression ignition (C.I) engine. Rice bran methyl ester (RBME) was produced from rice bran oil by transesterification using sodium hydroxide as catalyst. An experimental investigation was conducted on a single-cylinder four-stroke C.I engine to analyze the performance and emission characteristics of rice bran methyl ester (RBME) blended with diesel at 20% by volume (B20) with and without addition of 1000 ppm of two monophenolic antioxidant additives, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). The results showed that the BHA- and BHT-treated B20 blend decreased the brake specific fuel consumption (BSFC) by 2.1 and 1.2% and increased the brake thermal efficiency (BTE) by 1.04 and 0.5% compared to B20. The BHA- and BHT-treated B20 blend produced mean reductions in NOx emission of 12.2 and 9.6%, respectively, compared to B20. The carbon monoxide (CO) and hydrocarbon (HC) emissions of BHA- and BHT-treated B20 were increased by 14.8–16.6% and 10.6–11.2%, respectively, compared to B20. However the emission levels were lower than those of diesel.

Abstract: Rice bran oil (RBO) possesses a plasma cholesterol-lowering activity, while effect of wheat bran oil (WBO) on plasma cholesterol remains unknown. The present study compared the cholesterol-lowering activity of WBO with that of RBO in hamsters. Fifty-four male hamsters were divided into seven groups fed either a noncholesterol diet (NCD) or one of six high-cholesterol diets, namely HCD diet (0.2% cholesterol +9.5% lard), HCD+C diet (0.2% cholesterol +9.5% lard +0.5% cholestyramine), WL diet (0.2% cholesterol +4.8% Lard +4.8% WBO), WH diet (0.2% cholesterol +9.5% WBO), RL diet (0.2% cholesterol +4.8% Lard +4.8% RBO), and RH diet (0.2% cholesterol +9.5% RBO). Plasma total cholesterol (TC) in HCD group was 327.4 ± 31.8 mg/dL, while plasma TC in two WBO and two RBO groups was 242.2 ± 20.8, 243.1 ± 31.7, 257.1 ± 16.3, and 243.4 ± 46.0 mg/dL, respectively, leading to a decrease in plasma TC by 22–26% (P < 0.01). No significant difference in cholesterol-lowering potency was seen between WBO and RBO. Plasma choles...
TL;DR: In this article, a 2-level fractional factorial design (FFD) was applied for the selection of important process parameters influencing the lactic acid extraction significantly and then Box-Behnken design (BBD) was used to optimize the process conditions.
Abstract: Recently new development in the existing emulsion liquid membrane (ELM) technique is the use of green solvents and ionic liquids to form a stable green emulsion ionic liquid membrane (GEILM) which will help in curbing the environmental problems caused by petroleum-based solvents. In the present investigation, lactic acid (LA) extraction has been carried out by using GEILM. The w/o emulsion was prepared by using diluents solution (rice bran oil (70%, v/v) as a natural green solvent and hexane (30%, v/v) as an organic solvent), span 80 (2.66%, v/v of diluents solution) as a surfactant, aliquat336 (0.2%, v/v of diluents solution) as an ionic liquid, and sodium hydroxide (NaOH) as an internal phase reagent. The obtained GEILM was stable for 90 min which is ideal time for ELM operations. Therefore, rice bran oil (RBO) as a green solvent has shown a great potential for its applications in the various existing ELM processes. Initially, a 2- level fractional factorial design (FFD) was applied for the selection of important process parameters influencing the LA extraction significantly and then Box-Behnken design (BBD) was used to optimize the process conditions. 95 ± 3.5% LA extraction efficiency has been obtained under the optimized process conditions.

TL;DR: In this article, a comprehensive review on the antidiabetic property of rice bran and its derivative is presented. And the current review also focused on the reported anti-hyperglycemia activity of Rice bran derivatives, and its probable mechanism.
Abstract: Rice bran (RB) is one of the nutrient-rich agricultural byproducts. It is a composite of carbohydrates, lipids, proteins, fibers, minerals, and trace elements such as phosphorus, potassium, magnesium, calcium and manganese. The extraction and purification process influences the quality and quantity of rice bran oil, which is rich in tocopherols, tocotrienols, γ-oryzanol, and unsaturated fatty acids. The bioactive components of RB have been reported for exhibiting antioxidant, anti-inflammatory, hypocholesterolemic, anti-cancer, anti-colitis, and antidiabetic properties. In vitro and in vivo studies, and clinical trials in human volunteers revealed the anti-hyperglycemic activity of RB derived compounds. An updated comprehensive review on the antidiabetic property of RB and its derivative is required to appraise the current knowledge in the particular field. Thus, the present paper covered the composition and bioactivities of RB, and influence of extraction methods on the biological property of rice bran oil and rice bran extract. And the current review also focused on the reported anti-hyperglycemia activity of rice bran derivatives, and its probable mechanism.

TL;DR: Fundamental insight is provided into the structuring of hybrid systems containing waxes, which could be interesting for the production of low-saturated fat products in the food industry.
Abstract: BACKGROUND
Wax esters contribute to the transformation of liquid oils into solid-like oleogel systems, which can act as alternatives for trans- and/or saturated fats in food products. The use of solely waxes reduces the solid content, consistency and sensory quality in the final products. Therefore, a combination of sunflower wax and palm fat in rice bran oil was created to accomplish the hybrid low-saturated shortenings and margarines with a compatible structure and lower amounts of saturated fats.
RESULTS
During cooling of the hybrid shortenings, sunflower wax crystallized first and acted as nucleation sites for the crystallization of palm fat. At 5°C, a mixture of different crystal morphologies (α, β’, and β crystals) existed in the hybrid shortening. In margarine processing, the hybrid samples were subjected to a simultaneous cooling-emulsification, in which sunflower wax crystallized first at the interface and adsorbed onto the water droplets. Based on the hardness measurements, the maximum amount of palm fat replaceable by 1.0 %wt sunflower wax was up to 40% in shortenings and 25% in margarines. A higher amount of sunflower wax (2.5 %wt) reduced up to 40% of saturated fats in the hybrid emulsions.
CONCLUSION
The addition of 1.0 %wt sunflower wax enhanced the solid content and network strength of hybrid palm-based shortenings. Sunflower wax helped stabilizing the water droplets inside the wax-based crystalline network without flocculation during shear-cooling. This research provides fundamental insight into the structuring of hybrid systems containing waxes, which could be interesting to produce low-saturated fat products in food industry.

TL;DR: In this article, a review of the added value biomolecules in cereal by-products, and their health benefits, are reviewed in this chapter. But the authors focus on the use of oat bran as a starting raw material for the extraction of dietary fibers.
Abstract: Cereal by-products represent abundant and low-cost resources of phytochemicals with potential nutraceutical and pharmaceutical applications. γ-Oryzanols found in rice bran as well as in rice bran oil have 10 times higher antioxidant properties than tocopherols. Corn bran is one of the best sources of the potent antioxidant ferulic acid, compared to other cereals, fruits, and vegetables. Sorghum bran is a unique dietary source of 3-deoxyanthocyanidin, a rare type of flavonoid that has shown strong cytotoxic activities. Wheat and rye bran contain arabinoxylans, which contribute to a reduction in blood glucose, while oat bran is a starting raw material for the extraction of dietary fibers—β-glucans. These and many other added-value biomolecules in cereal by-products, and their health benefits, are reviewed in this chapter.
TL;DR: RBOs were found to be the rich source of oryzanols, phytosterols, Toc and T3, indicating that colored rice contained high concentration of phytochemicals in the oil than non-colored rice.
Abstract: Rice bran oil (RBO) especially from colored rice is rich in phytochemicals and has become popular in food, cosmetic, nutraceutical and pharmaceutical applications owing to its offering health benefits This study determined the contents of phytochemicals including oryzanols, phytosterols, tocopherols (Toc) and tocotrienols (T3) in RBOs extracted using different methods namely cold-press extraction (CPE), solvent extraction (SE) and supercritical CO2 extraction (SC-CO2) Two colored rice, Red Jasmine rice (RJM, red rice) and Hom-nin rice (HN, black rice), were studied in comparison with the popular Thai fragrant rice Khao Dawk Mali 105 (KDML 105, white rice) RBOs were found to be the rich source of oryzanols, phytosterols, Toc and T3 Rice varieties had a greater effect on the phytochemicals concentrations than extraction methods HN rice showed the significantly highest concentration of all phytochemicals, followed by RJM and KDML 105 rice, indicating that colored rice contained high concentration of phytochemicals in the oil than non-colored rice The RBO samples extracted by the CPE method had a greater concentration of the phytochemicals than those extracted by the SC-CO2 and SE methods, respectively In terms of phytochemical contents, HN rice extracted using CPE method was found to be the best
TL;DR: In this paper, the authors proposed to use ultrasound to enhance the kinetics of the Rice bran oil (RBO) extraction using supercritical CO2, which achieved a 12.65 wt% extraction yield.
Abstract: Rice bran oil (RBO) contains oryzanol and tocopherols. Its recovery was performed using conventional techniques with toxic solvents that leave residues in the final product. Supercritical fluid extraction (SFE) has been used, obtaining high global yields without residual solvent. This work proposes to use ultrasound to enhance the kinetics of the RBO extraction using supercritical CO2. The factors considered were ultrasound power (160 to 320 W) and sonication time (40 to 120 min), at 40 oC and 25 MPa. The best condition (160 W / 40 min) resulted in a 12.65 wt% extraction yield. When ultrasound was not used, the global yield dropped to 9.94 wt%, representing an increase of 27% of global yield due to ultrasound application. This increase can be assigned to the vibration effect promoted by the ultrasonic waves at the interfaces between the solid matrix and solvent. The extracts showed antioxidant activity towards the DPPH radical achieving values around 70% of inhibition. Precursors of oryzanol (campesterol, β-sitosterol, stigmasterol and 4-methylenecycloartanol) were identified in the SC-CO2 + US extracts. The results presented herein showed that SC-CO2 + US is a promising technology to be employed for the extraction of bioactive compounds.

TL;DR: The in vitro KGLP-NPRBO film-coated tablet release profile showed that no ORY was released at gastric pH while 85% of ORYwas released at pH 7.4 after 6 h; this would be expected to occur in the colorectal area; therefore, this study demonstrates the potential of K GLP- NPRBO to prevent colorctal cancer via a specific coloreCTal dietary supplement delivery system.
Abstract: Colorectal cancer occurs due to various factors. The important risks are dietary lifestyle and inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis. It has been found that the inhibitory enzyme cyclooxygenase-2 (COX-2) in the colorectal region can potentially reduce the risk of colorectal cancer. The present study investigated rice bran oil from natural purple rice bran, which exhibits antioxidant and anti-inflammatory activity. This study aimed to evaluate the bioactive compound content of natural purple rice bran oil (NPRBO) derived from native Thai purple rice and the anti-inflammatory activity of NPRBO in colorectal cancer cells, and to develop a colorectal delivery platform in the form of film-coated tablets. NPRBO from the rice bran of five different Thai purple rice cultivars, namely Khao’ Gam Leum-Phua (KGLP), Khao’ Gam Boung (KGB), Khao’ Gam Thor (KGT), Khao’ Gam Pah E-Kaw (KGPEK), and Khao’ Niaw Dam (KND), were extracted using the supercritical carbon dioxide extraction technique. The amount of γ-oryzanol (ORY), tocotrienols, and tocopherols present in NPRBOs and the in vitro anti-inflammatory activity of NPRBO were investigated. The highest anti-inflammatory NPRBO was transformed into a dry and free-flowing powder by liquisolid techniques. Then, it was compressed into core tablets and coated with Eudragit®L100 and Eudragit® NE30D. The in vitro release study of the film-coated NPRBO tablets was performed in three-phase simulated gastrointestinal media. The cultivar KGLP was superior to the other samples in terms of the ORY, tocotrienol and tocopherol contents and anti-inflammatory activity. Aerosil® was the most suitable absorbent for transforming NPRBO into a free-flowing powder and was used to prepare the NPRBO core tablets. The in vitro KGLP-NPRBO film-coated tablet release profile showed that no ORY was released at gastric pH while 85% of ORY was released at pH 7.4 after 6 h; this would be expected to occur in the colorectal area. Therefore, this study demonstrates the potential of KGLP-NPRBO to prevent colorectal cancer via a specific colorectal dietary supplement delivery system.
TL;DR: In this article, the authors evaluated the dielectric and physical properties in natural ester oil like sunflower oil (SFO), rice bran oil and corn oil using semi-conductive nanocomposites for different percentages of volume concentrations.
Abstract: In recent years, the interests on ester-based insulating oil as replacement of mineral oil in large power transformers are growing remarkable manner because of its environmental impact. Green insulating natural ester oil derived from natural sources results in higher biodegradability, fire resistant properties and so on. This research work presents the evaluation of dielectric and physical properties in natural ester oil like sunflower oil (SFO), rice bran oil and corn oil using semi-conductive nanocomposites for different percentages of volume concentrations. The AC breakdown voltage (BDV), loss tangent, DC resistivity, viscosity, dielectric permittivity, flash point and fire point properties are examined as per ASTM and IEC standards. Astoundingly, it is found that use of nanocomposite fluids (NCFs) results enhanced BDV and fire point properties in SFO samples. Hence, ester oil-based NCF serves as a compromising alternative insulation medium for power transformer application.
TL;DR: Overall, methanol was a superior acyl acceptor for the deacidification of high-acid RBO and the high reusability of immobilized SMG1-F278N indicates an economically attractive process.
Abstract: A highly efficient process for reducing the fatty acid (FA) content of high-acid rice bran oil (RBO) was developed by immobilized partial glycerides-selective lipase SMG1-F278N-catalyzed esterification/transesterification using methanol as a novel acyl acceptor. Molecular docking simulation indicated that methanol was much closer to the catalytic serine (Ser-171) compared with ethanol and glycerol, which might be one of the reasons for its high efficiency in the deacidification of high-acid RBO. Additionally, the reaction parameters were optimized to minimize the FA content of high-acid RBO. Under the optimal conditions (substrate molar ratio of methanol to FAs of 1.8:1, enzyme loading of 40 U/g, and at 30 °C), FA content decreased from 25.14 to 0.03% after 6 h of reaction. Immobilized SMG1-F278N exhibited excellent methanol tolerance and retained almost 100% of its initial activity after being used for ten batches. After purification by molecular distillation, the final product contained 97.86% triacylglycerol, 2.10% diacylglycerol, and 0.04% FA. The acid value of the final product was 0.09 mg KOH/g, which reached the grade one standard of edible oil. Overall, methanol was a superior acyl acceptor for the deacidification of high-acid RBO and the high reusability of immobilized SMG1-F278N indicates an economically attractive process.
TL;DR: In this article, an appropriate fractionation methodology is proposed for isolating the unsaponifiable matter into two fractions, squalene, phytosterols and fatty alcohols as fraction 1; tocopherols and γ- oryzanol as fraction 2.
Abstract: Rice bran oil is characterized by its unique composition of unsaponifiable matter such as oryzanol, squalene, sterols, tocopherols and fatty alcohols. Rice bran oil fatty acid distillate (RBOFAD) is an important by-product of physical refining plants. In the present study, an appropriate fractionation methodology is proposed for isolating the unsaponifiable matter into two fractions, squalene, phytosterols and fatty alcohols as fraction 1; tocopherols and γ- oryzanol as fraction 2. The two fractions together constitute the total unsaponifiable matter in the RBOFAD. The individual unsaponifiable matter components (γ-oryzanol 1.78g/100g, squalene 209.63 mg/100g, tocopherol 2.45mg/100g, total phytosterols 3.79g/100g and fatty alcohols 94.23g/100g) were isolated from RBOFAD by combining a chemical esterification process and liquid-liquid extraction process with 95% ethanol which extracted tocopherol, γ-oryzanol, sterols, squalene, FFA, monoglycerides; later with hexane extraction of the alkaline phase to remove squalene, sterols and fatty alcohols. The alkaline salts of tocopherols and γ-oryzanol are decomposed by the acidification and extraction of the unsaponifiable matter with n-hexane.
TL;DR: Rice bran extract is effective as a gastroprotective therapy sourced from natural ingredients in treating the incidence of gastric ulcers and is related to gamma oryzanol as a bioactive compound contained in rice bran (Oryza sativa L.).
Abstract: The presence of gamma-oryzanol in rice bran oil can be 10⁻20-fold higher than tocopherol and tocotrienol Gamma-oryzanol has various pharmacological properties The objective of this study was to evaluate the effectiveness of rice bran extract as a gastroprotective in reducing lesions in ethanol-induced acute gastric ulcer models in rat, using the ionic liquid-microwave-assisted extraction (IL-MAE) method Rice bran extract was obtained using the IL-MAE method with ionic liquid (IL), 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM]BF₄ (concentration 07 M), and a ratio of solid/liquid of 15 g/mL, 15 min extraction time, and 10% microwave power The rats were pretreated with rice bran extract at different doses (100, 200, and 400 mg/kg body weight; BW) for seven days and subsequently exposed to acute gastric lesions induced by 80% ethanol Omeprazole (36 mg/kg BW) was used as a standard anti-ulcer drug The ulcer index, gastric juice acidity, and mucus levels were measured to assess the degree of gastroprotection The results showed that the oral administration of rice bran extract at a dose of 400 mg/kg BW significantly inhibited the development of ulcer formation by 6675% and reduced gastric acid levels Moreover, gamma oryzanol and omeprazole protected the gastric mucosa from ethanol-induced gastric lesions by increasing the level of gastric mucus Rice bran extract is effective as a gastroprotective therapy sourced from natural ingredients in treating the incidence of gastric ulcers Most likely, this is related to gamma oryzanol as a bioactive compound contained in rice bran (Oryza sativa L)

TL;DR: In this article, the converted Rice Bran Oil (RBO) was blended with diesel to produce B5, B15 and B25 to determine physical properties and combustion performance, and the highest wall temperature was achieved at stoichiometric fuel mixture, while among the fuels, the wall temperature decreases as the biodiesel proportion increases in the blends.
Abstract: The concept of biodiesel as an alternative fuel is not an overnight thought, but the escalating prices, pungent emission gases and non-ecological behavior of fossil fuels has constrained the researchers to take the necessary steps. Biodiesels which are renewable in nature and having environmental friendly attribute have shown the potential to be the perfect replacement for the diesel fuels. Similarly, this study demonstrates the characteristics of Rice Bran Oil (RBO) which can be used as a latent substitute for diesel products. RBO is a vegetable oil, which is extracted from the rice bran (by-product of rice grain). Since rice is the staple diet for more than half of the world population, the quantity of RBO that can be extracted is enormous. In this study, the converted RBO into biodiesel (RBOBD) was blended with diesel to produce B5, B15 and B25 to determine physical properties and combustion performance. Owing to highly packed molecules of RBOBD, the properties such as density, kinematic viscosity and surface tension are higher in RBOBD and its blends than diesel. In contrast, the calorific value is lower. In the combustion test, the highest wall temperature is achieved at stoichiometric fuel mixture, while among the fuels, the wall temperature decreases as the biodiesel proportion increases in the blends. Moreover, in B25, emissions such as CO and SO 2 are 68% and 50% lower than that of diesel respectively. However, due to the additional oxygen present in the biodiesel structure, NO x emission of B25 is 15.67% higher than diesel.
