TL;DR: In this article, the authors identified a pair of soybean FATB coding genes, GmFATB1a and gmFatin1b, which were obtained via CRISPR/Cas9 and showed significant lower palmitic and stearic acid contents, 39-53% and 17-37%, respectively.
Abstract: Soybean (Glycine max) oil is one of the most widely used vegetable oils across the world. Breeding of soybean to reduce the saturated fatty acid (FA) content, which is linked to cardiovascular disease, would be of great significance for nutritional improvement. Acyl-acyl carrier protein thioesterases (FATs) can release free FAs and acyl-ACP, which ultimately affects the FA profile. In this study, we identified a pair of soybean FATB coding genes, GmFATB1a and GmFATB1b. Mutants that knock out either or both of the GmFATB1 genes were obtained via CRISPR/Cas9. Single mutants, fatb1a and fatb1b, showed a decrease in leaf palmitic and stearic acid contents, ranging from 11% to 21%. The double mutant, fatb1a:1b, had a 42% and 35% decrease in palmitic and stearic acid content, displayed growth defects, and were male sterility. Analysis of the seed oil profile revealed that fatb1a and fatb1b had significant lower palmitic and stearic acid contents, 39–53% and 17–37%, respectively, while that of the unsaturated FAs were the same. The relative content of the beneficial FA, linoleic acid, was increased by 1.3–3.6%. The oil profile changes in these mutants were confirmed for four generations. Overall, our data illustrate that GmFATB1 knockout mutants have great potential in improving the soybean oil quality for human health.

TL;DR: Overall, quercetin inhibited the formation of lipid oxidation products in thermally treated soybean oil by reacting with early intermediates in the lipid oxidation reaction, and quercETin derivatives formed in the process could be with enhanced cellular antioxidant activity.
Abstract: In this research, we studied the inhibitory mechanism of quercetin, one popular phenolic compound, against aldehyde formation in thermally treated soybean oil. It was found that quercetin reduced unsaturated aldehyde formation significantly, with the inhibitory effect decreased with the extension of the heating time. Meanwhile, quercetin had minimum effects on the fatty acid profile compared to untreated samples. Some new phenolic derivatives were formed in thermally treated soybean oil with quercetin, further analyzed by liquid chromatography-tandem mass spectrometry, and compared to newly synthesized derivatives (characterized by mass spectrometry and nuclear magnetic resonance spectroscopy). On the basis of their chemical structures, we proposed that quercetin reacted with 13-oxo-octadecadienoic acid, 10-oxo-hexadecenoic acid, and 10-oxo-octadecenoic acid formed from peroxidation of linoleic acid, palmitoleic acid, and oleic acid, respectively, to inhibit aldehyde formation. In addition, newly formed quercetin-3-O-hexanoate, quercetin-3-O-heptanoate, and quercetin-3-O-nonanoate showed weaker 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation scavenging activity and weaker antioxidant activity in soybean oil, which explained the decreased inhibitory activity of quercetin against aldehyde formation during heat treatment. More interesting, quercetin-3-O-hexanoate showed improved cellular antioxidant activity compared to the parent quercetin. Overall, quercetin inhibited the formation of lipid oxidation products in thermally treated soybean oil by reacting with early intermediates in the lipid oxidation reaction, and quercetin derivatives formed in the process could be with enhanced cellular antioxidant activity. Our results provide novel insight into the inhibitory mechanism of quercetin against the formation of lipid oxidation products.

TL;DR: Wang et al. as mentioned in this paper comprehensively qualified the potential environmental impact from the major edible vegetable oil production (i.e., soybean oil, rapeseed oil, and peanut oil) in China through the life cycle assessment method.
Abstract: With the increasing consumer demand and only 31% of the self-sufficiency rate, how to mitigate the supply safety of edible vegetable oil in an environmentally sustainable manner is a tremendous challenge for China. This study comprehensively qualified the potential environmental impact from the major edible vegetable oil production (i.e., soybean oil, rapeseed oil, and peanut oil) in China through the life cycle assessment method. Results show that rapeseed oil and peanut oil are environmentally friendly. More than 20% of environmental contamination could be avoided in 2025 by replacing the further increase in soybean oil production with a mix of the other products. The key contribution analysis indicates that the agricultural phase is a significant source of environmental pollution due to excessive fertilizer production and irrigation water consumption. During the oil processing phases of soybean oil and peanut oil, steam production also contributed to considerable environmental impact. Therefore, applying new fertilizers, developing water-saving irrigation technologies, and optimizing the steam heat exchange net are suggested. Moreover, increasing the oil extraction rate through electrotechnical technology has great potential in reducing the environmental damage caused by oil-bearing crop planting. Based on the spatial discrepancy in the agricultural phase, advantageous planting regions (e.g., Anhui, Henan, Shandong, and Jiangsu) are references for the further planting structure adjustment. Meanwhile, advocating scientific diets and optimizing the industry layout are recommended to ensure the healthy and sustainable development of China's edible vegetable oil industry.

TL;DR: In this article, a novel biobased UV-curable oligomer (GMAESO) was firstly synthesized from epoxidized soybean oil and gallic acid via a green one pot method.
Abstract: Typical resins for UV-assisted additive manufacturing (AM) are prepared from petroleum-based materials and therefore do not contribute to the growing AM industry trend of converting to sustainable bio-based materials. To satisfy society and industry’s demand for sustainability, renewable feedstocks must be explored; unfortunately, there are not many options that are applicable to photopolymerization. Nevertheless, some vegetable oils can be modified to be suitable for UV-assisted AM technologies. In this work, extended study, through FTIR and photorheology measurements, of the UV-curing of epoxidized acrylate from soybean oil (AESO)-based formulations has been performed to better understand the photopolymerization process. The study demonstrates that the addition of appropriate functional comonomers like trimethylolpropane triacrylate (TMPTA) and the adjusting of the concentration of photoinitiator from 1% to 7% decrease the needed UV-irradiation time by up to 25%. Under optimized conditions, the optimal curing time was about 4 s, leading to a double bond conversion rate (DBC%) up to 80% and higher crosslinking density determined by the Flory–Rehner empirical approach. Thermal and mechanical properties were also investigated via TGA and DMA measurements that showed significant improvements of mechanical performances for all formulations. The properties were improved further upon the addition of the reactive diluents. After the thorough investigations, the prepared vegetable oil-based resin ink formulations containing reactive diluents were deemed suitable inks for UV-assisted AM, giving their appropriate viscosity. The validation was done by printing different objects with complex structures using a laser based stereolithography apparatus (SLA) printer.
TL;DR: Li et al. as mentioned in this paper developed a liquid-interfacial surface-enhanced Raman spectroscopy (SERS) technology without sample pretreatment to realize the rapid and direct detection of ultra-trace PAHs in edible oil within 3min.
Abstract: Edible oil is easy to be polluted by polycyclic aromatic hydrocarbons (PAHs) in production, processing, storage and use. Rapid screening of oil quality and safety is a huge demand in food industry and government regulation. Usually, sample pretreatment is needed for PAHs detection due to the complexity of the oil base but greatly limits the detection speed. Here we develop a liquid-interfacial surface-enhanced Raman spectroscopy (SERS) technology without sample pretreatment to realize the rapid and direct detection of ultra-trace PAHs in edible oil within 3 min. A quantitative analysis curve of benzopyrene (BaP) content in soybean oil is established in the range of 0.1 ppb–100 ppm with a high coefficient correlation (R2) of 0.9959 in curve fitting. It was found that only 4.5 h of frying would make the BaP content exceed the limit of 10 ppb in the Chinese Food Safety National Standard. Four common PAHs can be quickly identified in frying oil samples collected from special snack streets and the SERS profiles of soybean oil with adulteration of refined gutter oil could be well classified. This study paves a reliable method to rapid analyze edible oil with broad application prospects in the field of grain and oil safety.

TL;DR: In this article, the authors applied NMR analysis to avocado oil to differentiate it from other oils including olive, canola, high-oleic (HO) safflower, HO sunflower and soybean oil using commercial and lab-made samples of avocado oils.
Abstract: Avocado oil is a food product of high commercial and nutritional value. As a result, it can be a subject of adulteration similar to other high-value edible oils, such as olive oil. For olive oil and many other foods products, NMR spectroscopy has been successfully used for authentication and quality assessment. In this study, we apply NMR analysis to avocado oil to differentiate it from other oils including olive, canola, high-oleic (HO) safflower, HO sunflower and soybean oil using commercial and lab-made samples of avocado oils. NMR allowed the rapid analysis of the fatty acid profile and detection of minor compounds, such as sterols, oxidation products, and hydrolysis products, which can be used to assess oil quality and authenticity. The NMR assignment was conducted using traditional 2D NMR and the novel NOAH super-sequences. Combining chemometrics with NMR enabled us to differentiate between avocado oil and other oils. Avocado oil has compositional similarities with other vegetable oils, such as HO sunflower and HO safflower oil, which can be used as potential adulterants. Despite these similarities, NMR-based metabolomics captured differences in the levels of certain compounds including fatty acids, terpenes, sterols, and oxidation products to detect adulteration and for quality control purposes.
