TL;DR: In this article, a waste snail shell (Pila spp.) derived catalyst was used to produce biodiesel from soybean oil at room temperature for the first time, achieving a high biodiesel yield of 98% under optimized reaction conditions such as a calcination temperature of 900 °C, a catalyst loading of 3 wt, a reaction time of 7 h and a methanol to oil ratio of 6
Abstract: A waste snail shell (Pila spp.) derived catalyst was used to produce biodiesel from soybean oil at room temperature for the first time. The snail shell was calcined at different temperatures of 400–1000 °C. The synthesized catalysts underwent XRD, SEM, TEM, EDS, FTIR, XRF, TG/DTA and N2 adsorption–desorption isotherm (BET) analysis. The major component CaO was determined at a calcination temperature of 900 °C as depicted in the XRD results. 100% conversion of soybean oil to methyl ester biodiesel was obtained, as confirmed by 1H NMR. A biodiesel yield of 98% was achieved under optimized reaction conditions such as a calcination temperature of 900 °C, a catalyst loading of 3 wt%, a reaction time of 7 h and a methanol to oil ratio of 6 : 1, and biodiesel conversion was confirmed by FT-NMR and IR spectroscopies. A total of 9 fatty acid methyl esters (FAMEs) were identified in the synthesized biodiesel by the retention time and fragmentation pattern data of GC-MS analysis. The catalyst was recycled 8 times without appreciable loss in its catalytic activity. A high biodiesel yield of 98% was obtained under these optimised conditions. The catalyst has the advantage of being a waste material, therefore it is easily prepared, cost free, highly efficient, biogenic, labor effective and environmentally friendly, making it a potential candidate as a green catalyst for low cost production of biodiesel at an industrial scale.

TL;DR: In this paper, a dynamic vulcanization method to toughen polylactide (PLA) using sebacic acid cured epoxidized soybean oil (VESO), a fully sustainable and biodegradable component, was reported.
Abstract: The use of soybean oil or its derivatives to toughen polylactide (PLA) usually leads to limited toughening efficiency, due to the incompatibility between toughening agents and parent PLA. Herein, we report a dynamic vulcanization method to toughen PLA using sebacic acid cured epoxidized soybean oil (VESO), a fully sustainable and biodegradable component. A series of sebacic acid cured epoxidized soybean oil precursors (SEPs) were prepared with different carboxyl/epoxy equivalent ratio (R), which consequently dictates the chemical structure and the morphology of PLA/VESO blends after the dynamic vulcanization. We demonstrated that the chemical structure of VESO plays a critical role in the compatibility, morphology, and toughness of the PLA/VESO blends. By optimizing the R-value, supertoughened PLA blends can be obtained, as evidenced by the significant improvement in the tensile toughness (up to 150.6 MJ/m3) and the impact strength (up to 542.3 J/m). The results of the toughening mechanism from the morpho...

TL;DR: In this article, the authors conducted hydrothermal liquefaction (HTL) of soybean oil, soy protein, microcrystalline cellulose, xylose, and lignin as individual compounds and binary, ternary, quaternary, and quinary mixtures at 350 °C for 30 min.
Abstract: We conducted hydrothermal liquefaction (HTL) of soybean oil, soy protein, microcrystalline cellulose, xylose, and lignin as individual compounds and binary, ternary, quaternary, and quinary mixtures at 350 °C for 30 min. The 34.5 wt % biocrude yield from HTL of the quinary mixture, which mimics the biochemical composition of swine manure, is much higher than the 21.5 wt % yield calculated from the weighted average yields from HTL of the individual components. HTL of binary mixtures of protein and cellulose, protein and xylose, cellulose and lignin, and xylose and lignin revealed synergistic effects on biocrude yield. On the other hand, HTL of soybean oil and lignin together exhibited an antagonistic effect on biocrude yield. These results from individual compounds and binary mixtures lead to a new model that can predict the yield, higher heating value, and C, H, and N content of biocrude from HTL of ternary, quaternary, and quinary mixtures of the biomolecules used in this study as well as in biocrude fro...

TL;DR: In this article, a ring-opening reaction of epoxidized soybean oil (ESO) with hydroxyethyl methacrylated maleate (HEMAMA) precursor, a synthesized unsaturated carboxylic acid having two active C═C groups and a side methyl group, was studied.
Abstract: Novel soybean-oil-based (SBO-based) epoxy acrylate (EA) resins were developed via ring-opening reaction of epoxidized soybean oil (ESO) with hydroxyethyl methacrylated maleate (HEMAMA) precursor, a synthesized unsaturated carboxylic acid having two active C═C groups and a side methyl group. Experimental conditions for the synthesis of the precursor and the SBO-based EA (ESO-HEMAMA) product were studied, and their chemical structures were confirmed by FT-IR, 1H NMR, 13C NMR, and gel permeation chromatography. Subsequently, the volatility of HEMAMA was studied and compared with acrylic acid (AA). Furthermore, gel contents and ultimate properties of the UV-cured ESO-HEMAMA resins were investigated and compared with a commercial acrylated ESO (AESO) resin. At last, UV-curing behaviors of the SBO-based EA resins were determined by real-time IR. It was found that the HEMAMA precursor showed much lower volatility than AA, and the optimal pure ESO-HEMAMA resin possessed a C═C functionality up to 6.02 per ESO and ...

TL;DR: In this paper, a review of reports and journal articles on biodiesel feedstock resources over the last decade from 2006 to 2016 were reviewed in order to better understand the effects of feedstock characteristics on engine performance and emissions.
Abstract: Feedstock for biodiesel production has changed over time and it varies depending on regions. Reports and journal articles on biodiesel feedstock resources over the last decade from 2006 to 2016 were reviewed in this article. The regional trends still maintain as the USA and the EU still predominantly use soybean oil and rapeseed oil, respectively, and palm oil is the major source of biodiesel in Asia. It is expected that the food-crop based biodiesel will continue to be dominant for the next decade. However, it was found that uses of animal fats and used cooking oil are increasing both in the USA and the EU. Because of the increasing diversity in feedstock inputs to biodiesel, it is necessary to better understand the effects of feedstock characteristics on engine performance and emissions. In this review, we limit the reports on biodiesel emissions to those who used 100% biodiesel combusted in a one-cylinder, four-stroke, direct injection engine set up in a laboratory. All the emission results were obtained from the same or similar engine conditions to fairly compare them. CO, CO2, NOx, and PM emissions are compared between the biodiesels derived from soybean oil, rapeseed oil, palm oil, jatropha oil, used cooking oil, animal fats, and algal oil. It was found that more emission studies are needed for algal biodiesel. More in-depth studies are necessary for PM characteristics including the compositions of trace metals, elemental and organic carbon. © 2017 American Institute of Chemical Engineers Environ Prog, 2017

TL;DR: SVEJKOVSK et al. as discussed by the authors studied the formation and decomposition of 3-chloropropane-1,2-diol esters in models simulating processed foods.
Abstract: SVEJKOVSK A B., DOLE ŽAL M., VEL ISEK J. (2006): Formation and decomposition of 3-chloropropane1,2-diol esters in models simulating processed foods. Czech J. Food Sci., 24: 172–179. The formation of 3-chloropropane-1,2-diol (3-MCPD) released from its esters with higher fatty acids was studied using the recognised precursors of 3-MCPD (tripalmitin, 1,3-dipalmitin, 1-monopalmitin and soybean oil) in the presence of sodium chloride. The precursors were reacted with sodium chloride in an emulsion stabilised with an emulsifier under conditions which modelled the thermal treatment of foods during processing. The highest amount of bound 3-MCPD (released from its esters) was formed from 1-monopalmitin followed by 1,3-dipalmitin, whereas tripalmitin and soybean oil yielded the lowest levels of bound 3-MCPD. Four sets of experiments were then carried out aimed at monitoring the influence of various factors (soybean oil amount, NaCl content, water content, and temperature) on the yield of bound 3-MCPD. The formation of bound 3-MCPD was directly proportional to the concentration of either oil or NaCl. The highest amount of bound 3-MCPD was formed in media containing approximately 20% water. The amount of bound 3-MCPD decreased with increasing temperature over the range 100–230°C and reached its highest value at 100°C. Models with 1,2-dipalmitoyl-3-chloropropane-1,2-diol showed that the decomposition rate of this ester rapidly increased with increasing temperature over the range 100–230°C being the lowest at 100°C and the highest at 230°C.

TL;DR: In this paper, the authors describe the potential of Acrocomia aculeata, popularly known as macauba, which is an American palm from the tropical zones which presents oil productivity and quality similar to that of the oil palm.
Abstract: The growing global demand for vegetable oils for food and for replacing fossil fuels leads to increased oilseeds production. Almost 122 of the current 187 million tons of vegetable oils produced in the world correspond to palm and soybean oils. The oil palm is cultivated in the tropical zone, in areas formerly occupied by forests, and soybean oil is a by-product of protein meal production. The diversification of raw materials for the vegetable oil market is thus strategic for both food and non-food sectors. Sources for vegetable oil should be economically competitive and provide sustainability indexes higher than that provided by oil palm and soybean. In this context, we describe the potential of Acrocomia aculeata , popularly known as macauba. Macauba is an American palm from the tropical zones which presents oil productivity and quality similar to that of the oil palm. It grows spontaneously in a wide range of environments and it is not very water demanding. Macauba palm has a high potential for oil production and for diversification of co-products with some potential of value aggregation. Such a perennial and sustainable species will probably fulfill the requirements to become an important new commercial oilseed crop.
TL;DR: In this paper, the use of an ultrasound system for the enzymatic transesterification of oils using combi-lipases as biocatalyst was described, and the results showed that ultrasound technology, in combination with the application of enzyme mixtures, known as combilipases, could be a promising route to reduce the overall process costs of biodiesel.
Abstract: This work describes the use of an ultrasound system for the enzymatic transesterification of oils using combi-lipases as biocatalyst. The reactions were carried out evaluating the individual use of waste oil and fresh soybean oil, and the immobilized lipases CALB, TLL, and RML were used as biocatalysts. It was performed in a mixture design of three factors to obtain the ideal mixture of lipases according to the composition of fatty acids present in each oil, and the main reaction variables were optimized. After 18 h of reaction, ultrasound provided a biodiesel yield of about 90% when using soybean oil and 70% using the waste oil. The results showed that ultrasound technology, in combination with the application of enzyme mixtures, known as combi-lipases, and the use of waste oil, could be a promising route to reduce the overall process costs of enzymatic production of biodiesel.

TL;DR: A new ethyl methane sulfonate mutagenized soybean population was generated using the newly released germplasm, JTN-5203 (maturity group V), and phenotypic variations observed in this population include changes in leaf morphology, plant architecture, seed compositions, and yield.
Abstract: Soybean is an important oil-producing crop in the Fabaceae family and there are increasing demands for soybean oil and other soybean products. Genetic improvement of soybean is needed to increase its production. In order to provide genetic diversity and resources for identifying important genes, a new ethyl methane sulfonate (EMS) mutagenized soybean population was generated using the newly released germplasm, JTN-5203 (maturity group V). Treatment of soybean seeds with 60 mM EMS concentration was found to be suitable for inducing mutation. A total of 1,820 M1 individuals were produced from 15,000 treated seeds. The resulting M2 population was planted in the field for phenotyping. After harvest, seed traits including total oil, protein, starch, moisture content, fatty acid and amino acid compositions were measured by NIR. Phenotypic variations observed in this population include changes in leaf morphology, plant architecture, seed compositions, and yield. Of most interest, we identified plants with increased amounts of total protein (50% vs. 41% for control) and plants with higher amounts of total oil (25% vs. 21.2% control). Similarly, we identified plants with increases in oleic acid content and decreases in linoleic acid and linolenic acid. This EMS mutant population will be used for further studies including screening for various traits such as amino acid pathways, allergens, phytic acids, and other important soybean agronomic traits. In addition, these mutant individuals will be evaluated in the next generation to assess the heritability. Beneficial traits from these mutants can be exploited for future soybean breeding programs. This germplasm can also be used for discovering novel mutant alleles and for functional gene expression analysis using reverse genetics tools such as TILLING.

TL;DR: It was found that particles produced from olive oil led to the highest deposition in the human respiratory tract, and minimizing the moisture content of ingredients before cooking and giving priority to the use of peanut oil instead of olive oil to reduce human exposure to PM.
Abstract: Cooking fume produced by oil and food at a high temperature releases large amount of fine particulate matter (PM) which have a potential hazard to human health. This chamber study investigated particle emission characteristics originated from using four types of oil (soybean oil, olive oil, peanut oil and lard) and different kinds of food materials (meat and vegetable). The corresponding emission factors (EFs) of number, mass, surface area and volume for particles were discussed. Temporal variation of size-fractionated particle concentration showed that olive oil produced the highest number PM concentration for the entire cooking process. Multiple path particle dosimetry (MPPD) model was performed to predict deposition in the human respiratory tract. Results showed that the pulmonary airway deposition fraction was the largest. It was also found that particles produced from olive oil led to the highest deposition. We strongly recommend minimizing the moisture content of ingredients before cooking and giving priority to the use of peanut oil instead of olive oil to reduce human exposure to PM.

TL;DR: Jokic et al. as mentioned in this paper evaluated the triacylglycerol composition and concentration of fatty acids in soybean oil fractions and found that myristic, palmitic, linoleic and linolenic fatty acids were the highest in the first fraction and then decreased, while the concentrations of stearic and oleic acids showed the opposite trend.
Abstract: Jokic S., Sudar R., Svilovic S., Vidovic S., Bilic M., Velic D., Jurkovic V. (2013): Fatty acid compo-sition of oil obtained from soybeans by extraction with supercritical carbon dioxide Czech J. Food .Sci., 31 : 116–125. Soybean oil fractions were obtained by collecting the extract at different time intervals during supercritical carbon dioxide extraction. The extraction was performed at the following temperatures: 313, 323, and 333 K, and at pressures of 300, 400, and 500 bar. The triacylglycerol composition and concentration of fatty acids in soybean oil fractions was evaluated. The fatty acid and triacylglycerol compositions of soybean oil obtained with supercritical carbon dioxide was compared with the soybean oil extracted with n -hexane. The extraction temperature and pressure, did not influ-ence the fatty acids compositions which, however, differed in different fractions collected at different time intervals. The concentrations of myristic, palmitic, linoleic, and linolenic fatty acids of soybean oil were the highest in the first fraction and then decreased, while the concentrations of stearic and oleic acids showed the opposite trend. The solu -bility of all fatty acids increased with the pressure from 300 to 400 bar at constant temperature, while in the interval from 400 to 500 bar the solubility decreased with long chain fatty acids (C20–C24).
TL;DR: Biotransformation rates were influenced by compositions of fatty acids and purity of the starting material and may contribute to the production of industrially relevant C9 chemicals from renewable oils and fatty acids by simultaneous enzyme/whole-cell biotransformation.
TL;DR: In this article, the antioxidant efficacy of peanut skin extracts (PSE) to prevent the oxidative processes of soybean oil during storage and compare the results with those obtained after using a positive control with butylated hydroxytoluene (BHT) under accelerated oxidation conditions (16 −d at 60 −°C).
Abstract: The aim of this study was to determine the antioxidant efficacy of peanut skin extracts (PSE) to prevent the oxidative processes of soybean oil during storage and to compare the results with those obtained after using a positive control with butylated hydroxytoluene (BHT) under accelerated oxidation conditions (16 d at 60 °C). Progress in lipid oxidation of soybean oil was followed by chemical indices (peroxide value, p-anisidine value, and conjugated dienes) at the end of the storage. A second goal was to achieve the optimal conditions for the extraction of antioxidant molecules from peanut skin using response surface methodology. At level of 750 mg/kg of PSE, primary and secondary oxidation inhibition was equivalent to the obtained with BHT, hence our results revealed PSE as an effective antioxidant for the stabilization of soybean oil. The best conditions for the recovery of antioxidant compounds were dependent on the variables measured but, in general, concentration of ethanol (73.9%) and temperature of 66.5 °C maximized the responses and the recovery of activities was not significantly influenced by extracting time.
TL;DR: The protection ability of organic goji berry extract as an alternative to synthetic antioxidants against oxidation of soybean oil was investigated in this paper, where the main bioactive compounds of the optimized extract were identified and quantified.
