TL;DR: BSLF inclusion guaranteed satisfactory productive performances, carcass traits and overall meat quality, thus suggesting that BSLF could be a promising new feed ingredient for chickens.
Abstract: The present research studied for the first time the potential application of the fat derived from the black soldier fly larvae fat (BSLF) in substitution to the soybean oil in the diet for broiler chickens: growth performances, feed-choice, blood traits, carcass characteristics and meat quality were considered in this study. A total of 150 male broiler chicks (Ross 308) at one-day of age were randomly allotted to 3 dietary treatments (5 replicates and 10 birds/pen): a basal control diet (C group), and the same diet in which the soybean oil was replaced by 50% (CH group) or 100% (H group) BSLF. Growth performances, feed-choice test, blood traits and slaughtering performances were not influenced by diets. Independently of BSLF inclusion, broiler chickens breast meat had also similar crude protein and ether extract contents and displayed similar thawing loss. Furthermore, pH, L*, a*, b* colour values, and drip loss were unaffected by dietary treatments both at 0 and 9 days of refrigerated storage. As...

TL;DR: This is the first GWA study conducted on seed composition traits solely in wild soybean populations, and a number of QTLs were found that have not been previously discovered, and some new candidate genes whose molecular effects on these traits need to be further studied.
Abstract: Cultivated soybean (Glycine max) is a major agricultural crop that provides a crucial source of edible protein and oil. Decreased amounts of saturated palmitic acid and increased amounts of unsaturated oleic acid in soybean oil are considered optimal for human cardiovascular health and therefore there has considerable interest by breeders in discovering genes affecting the relative concentrations of these fatty acids. Using a genome-wide association (GWA) approach with nearly 30,000 single nucleotide polymorphisms (SNPs), we investigated the genetic basis of protein, oil and all five fatty acid levels in seeds from a sample of 570 wild soybeans (Glycine soja), the progenitor of domesticated soybean, to identify quantitative trait loci (QTLs) affecting these seed composition traits. We discovered 29 SNPs located on ten different chromosomes that are significantly associated with the seven seed composition traits in our wild soybean sample. Eight SNPs co-localized with QTLs previously uncovered in linkage or association mapping studies conducted with cultivated soybean samples, while the remaining SNPs appeared to be in novel locations. Twenty-four of the SNPs significantly associated with fatty acid variation, with the majority located on chromosomes 14 (6 SNPs) and seven (8 SNPs). Two SNPs were common for two or more fatty acids, suggesting loci with pleiotropic effects. We also identified some candidate genes that are involved in fatty acid metabolism and regulation. For each of the seven traits, most of the SNPs produced differences between the average phenotypic values of the two homozygotes of about one-half standard deviation and contributed over 3% of their total variability. This is the first GWA study conducted on seed composition traits solely in wild soybean populations, and a number of QTLs were found that have not been previously discovered. Some of these may be useful to breeders who select for increased protein/oil content or altered fatty acid ratios in the seeds. The results also provide additional insight into the genetic architecture of these traits in a large sample of wild soybean, and suggest some new candidate genes whose molecular effects on these traits need to be further studied.

TL;DR: In this paper, itaconic acid was monomethylated with methanol to produce itaconate, and then itaconated epoxidized soybean oil (IESO) was obtained by melt ring-opening esterification of monometric acid with ESO.
Abstract: In this paper, itaconic acid was monomethylated with methanol to produce monomethyl itaconate, and then monomethyl itaconated epoxidized soybean oil (IESO) was obtained by melt ring-opening esterification of monomethyl itaconate with ESO. For comparison, acrylated epoxidized soybean oil (AESO) was also synthesized from ESO and acrylic acid with the same synthetic method. The chemical structures of monomethyl itaconate, IESO, and AESO were characterized in detail by differential scanning calorimetry (DSC), FTIR, and 1H NMR. The isothermal thermogravimetric analysis at 30, 60, and 90 °C indicated that monomethyl itaconate exhibited extremely low volatility even at 90 °C, while acrylic acid volatilized very fast even at 30 °C, which suggested that monomethyl itaconate could be used as a green alternative to acrylic acid. Under UV radiation, IESO showed good copolymerization ability with reactive monomers such as glycidyl methacrylate modified itaconic acid (IG), trimethylolpropane triacrylate (TMPTMA), and s...

TL;DR: Soybean oil was structured with carnauba wax to develop solid-like oleogels that were evaluated in instant fried noodles as an alternative to deep-fat frying medium containing high saturated fat.
Abstract: Soybean oil was structured with carnauba wax to develop solid-like oleogels that were evaluated in instant fried noodles as an alternative to deep-fat frying medium containing high saturated fat. A more rapid change in viscosity with temperature was observed in the oleogels with increasing levels of carnauba wax. Upon heating, the storage (G′) and loss (G″) moduli of oleogels and palm oil decreased with a greater temperature dependence of G′, showing the crossover of G’ and G”. Compared to the palm and soybean oil-fried noodles, the samples fried in the oleogels absorbed approximately 16% less oil which could be correlated with their scanning electron microscopic images. However, there were no negative effects on the noodle texture. The levels of saturated fatty acids in the oleogel-fried noodles were significantly reduced (19 g/100 g), compared to the palm oil-fried noodles (54 g/100 g). Lower peroxide values during storage were observed in the following order: palm oil, oleogel, and soybean oil-fried noodles.

TL;DR: Sunflower oil (SFO), soybean oil, canola oil, ethanol, and water were utilized as co-solvents to support supercritical carbon dioxide (SC-CO 2 ) extraction of total carotenoid (TC), fucoxanthin (FX), and phlorotannin (PT) from brown seaweed ( Saccharina japonica).
Abstract: Sunflower oil (SFO), soybean oil, canola oil, ethanol, and water were utilized as co-solvents to support supercritical carbon dioxide (SC-CO 2 ) extraction of total carotenoid (TC), fucoxanthin (FX), and phlorotannin (PT) from brown seaweed ( Saccharina japonica ). A steepest ascent method with various temperatures [45–55 °C], pressures [200–300 bar], and co-solvent flow rates [0.50–2.00 (% of CO 2 , w/w)] was used to define the best operative co-solvents to enhance the extraction yields followed by response surface methodology (RSM) to optimize the extraction conditions. The best conditions for the yield of TC and FX were 50.62 °C, 300 bar, and 2.00% of SFO, while for PT it was 48.98 °C, 300 bar, and 2.00% of water, respectively. Overall extraction curves were determined for the optimized conditions, and experimental data were used to estimate the kinetic parameters. SFO as co-solvent showed higher fatty acid content, antioxidant activity, and oil stability than the control (SC-CO 2 only).
TL;DR: This work used both a linkage and association mapping methodology to dissect the genetic basis of seed oil content of Chinese soybean cultivars in various environments in the Jiang-Huai River Valley and found 8 QTLs were found that explained a range of phenotypic variance from 6.3 to 26.3% in certain planting environments.
Abstract: Soybean oil is the most widely produced vegetable oil in the world and its content in soybean seed is an important quality trait in breeding programs. More than 100 quantitative trait loci (QTLs) for soybean oil content have been identified. However, most of them are genotype specific and/or environment sensitive. Here, we used both a linkage and association mapping methodology to dissect the genetic basis of seed oil content of Chinese soybean cultivars in various environments in the Jiang-Huai River Valley. One recombinant inbred line (RIL) population (NJMN-RIL), with 104 lines developed from a cross between M8108 and NN1138-2, was planted in five environments to investigate phenotypic data, and a new genetic map with 2,062 specific-locus amplified fragment (SLAF) markers was constructed to map oil content QTLs. A derived F2 population between MN-5 (a line of NJMN-RIL) and NN1138-2 was also developed to confirm one major QTL. A soybean breeding germplasm population (279 lines) was established to perform a genome-wide association study (GWAS) using 59,845 high-quality single nucleotide polymorphism (SNP) markers. In the NJMN-RIL population, 8 QTLs were found that explained a range of phenotypic variance from 6.3 to 26.3% in certain planting environments. Among them, qOil-5-1, qOil-10-1, and qOil-14-1 were detected in different environments, and qOil-5-1 was further confirmed using the secondary F2 population. Three loci located on chromosomes 5 and 20 were detected in a two-year long GWAS, and one locus that overlapped with qOil-5-1 was found repeatedly and treated as the same locus. qOil-5-1 was further localized to a linkage disequilibrium (LD) block region of approximately 440 kb. These results will not only increase our understanding of the genetic control of seed oil content in soybean, but will also be helpful in marker-assisted selection (MAS) for breeding high seed oil content soybean and gene cloning to elucidate the mechanisms of seed oil content.

TL;DR: The soybean oil wastes treated with core and frit lipases through transesterification reaction were less toxic than the untreated oils, thus confirming that cooking oil wastes can be bioremediated using orange lipases.
Abstract: Cooking oil waste leads to well-known environmental impacts and its bioremediation by lipase-based enzymatic activity can minimize the high cytotoxic potential. In addition, they are among the biocatalysts most commercialized worldwide due to the versatility of reactions and substrates. However, although lipases are able to process cooking oil wastes, the products generated from this process do not necessarily become less toxic. Thus, the aim of the current study is to analyze the bioremediation of lipase-catalyzed cooking oil wastes, as well as their effect on the cytotoxicity of both the oil and its waste before and after enzymatic treatment. Thus, assessed the post-frying modification in soybean oil and in its waste, which was caused by hydrolysis reaction catalyzed by commercial and home-made lipases. The presence of lipases in the extracts obtained from orange wastes was identified by zymography. The profile of the fatty acid esters formed after these reactions was detected and quantified through gas chromatography and fatty acids profile compared through multivariate statistical analyses. Finally, the soybean oil and its waste, with and without enzymatic treatment, were assessed for toxicity in cytotoxicity assays conducted in vitro using fibroblast cell culture. The soybean oil wastes treated with core and frit lipases through transesterification reaction were less toxic than the untreated oils, thus confirming that cooking oil wastes can be bioremediated using orange lipases.

TL;DR: Li2TiO3 has been used as a solid catalyst for transesterification of soybean oil into biodiesel as mentioned in this paper, which achieved a conversion rate of 98.5% under optimal reaction conditions, namely a methanol:oil molar ratio of 24:1, a catalyst amount of 6.5%, and a reaction temperature of 65°C for 2h.
Abstract: This study focuses on the transesterification of soybean oil into biodiesel using Li2TiO3. Li2TiO3 is prepared through a solid-state reaction that involves mixing and grinding TiO2 and Li2CO3 followed by the calcination at 800 °C for 2 h. The prepared Li2TiO3 is characterized by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FE-SEM), and BET, and the Hammett indicator is applied to obtain their physical and chemical properties. Li2TiO3 has never been studied as a solid catalyst for transesterification reaction. Under optimal reaction conditions, namely a methanol:oil molar ratio of 24:1, a catalyst amount of 6 wt%, and a reaction temperature of 65 °C for 2 h, a biodiesel conversion rate of 98.5% is obtained. Moreover, different vegetable oil and used cooking oil are used as the raw materials for the biodiesel production. Li2TiO3 can be easily recovered and reused for ten cycles without significant deactivation.

TL;DR: Ectopic integration and heterologous expression of fatty acid elongases from different plants in Rhodosporidium toruloides resulted in the de novo synthesis of erucic acid and nervonic acid in this oleaginous yeast.
Abstract: Erucic acid (cis-docosa-13-enoic acid, C22:1∆13) and nervonic acid (cis-tetracosa-15-enoic acid, C24:1 ∆15) are important renewable feedstocks in plastic, cosmetic, nylon, and lubricant industries. Furthermore, nervonic acid is also applied to the treatment of some neurological diseases. However, the production of these two very long-chain fatty acids (VLCFA) is very limited as both are not present in the main vegetable oils (e.g., soybean, rapeseed, sunflower, and palm). Ectopic integration and heterologous expression of fatty acid elongases (3-ketoacyl-CoA synthases, KCS) from different plants in Rhodosporidium toruloides resulted in the de novo synthesis of erucic acid and nervonic acid in this oleaginous yeast. Increasing KCS gene copy number or the use of a push/pull strategy based on the expression of elongases with complementary substrate preferences increased significantly the amount of these two fatty acids in the microbial oils. Oil titers in 7-L bioreactors were above 50 g/L, and these two VLCFA represented 20-30% of the total fatty acids. This is the first time that microbial production of these types of oils is reported.
TL;DR: The herein-developed materials widen the potential of ternary PLA formulations by a cost effective blending method with PHB and PCL and compatibilization with vegetable oil-based additives.
Abstract: Ternary blends of poly(lactic acid) (PLA), poly(3-hydroxybutyrate) (PHB) and poly(e-caprolactone) (PCL) with a constant weight percentage of 60%, 10% and 30% respectively were compatibilized with soybean oil derivatives epoxidized soybean oil (ESO), maleinized soybean oil (MSO) and acrylated epoxidized soybean oil (AESO). The potential compatibilization effects of the soybean oil-derivatives was characterized in terms of mechanical, thermal and thermomechanical properties. The effects on morphology were studied by field emission scanning electron microscopy (FESEM). All three soybean oil-based compatibilizers led to a noticeable increase in toughness with a remarkable improvement in elongation at break. On the other hand, both the tensile modulus and strength decreased, but in a lower extent to a typical plasticization effect. Although phase separation occurred, all three soybean oil derivatives led somewhat to compatibilization through reaction between terminal hydroxyl groups in all three biopolyesters (PLA, PHB and PCL) and the readily reactive groups in the soybean oil derivatives, that is, epoxy, maleic anhydride and acrylic/epoxy functionalities. In particular, the addition of 5 parts per hundred parts of the blend (phr) of ESO gave the maximum elongation at break while the same amount of MSO and AESO gave the maximum toughness, measured through Charpy’s impact tests. In general, the herein-developed materials widen the potential of ternary PLA formulations by a cost effective blending method with PHB and PCL and compatibilization with vegetable oil-based additives.
TL;DR: Overall, lipid digestion was heavily altered by the physical state of the dispersed oil phase within O/W emulsions, which decreased with increasing solid fat content, and followed an exponential relationship.
Abstract: Emulsified lipid digestion was tailored by manipulating the physical state of dispersed oil droplets in whey protein stabilized oil-in-water (O/W) emulsions, where the oil phase consisted of one of five ratios of soybean oil (SO) and fully hydrogenated soybean oil (FHSO). The evolution in particle size distribution, structural changes during oral, gastric, and intestinal digestion, and free fatty acid release during intestinal digestion were all investigated. Irrespective of the physical state and structure of the dispersed oil/fat, all emulsions were stable against droplet size increases during oral digestion. During gastric digestion, the 50:50 SO:FHSO emulsion was more stable against physical breakdown than any other emulsion. All emulsions underwent flocculation and coalescence or partial coalescence upon intestinal digestion, with the SO emulsion being hydrolyzed the most rapidly. The melting point of all emulsions containing FHSO was above 37 °C, with the presence of solid fat within the dispersed o...
