“…Consequently, storage conditions are very important in the storage process. If the standard of containers for EPOs is not strict, EPOs will be contaminated with plasticizers, heavy metal, synthetic antioxidants (Carvalho et al, 2019), or other toxic substances during storage. The types of rancidity are oxidative rancidity, hydrolytic rancidity, and ketone rancidity (Haman et al, 2017).…”

Edible plant oil (EPO) is an indispensable nutritional resource for human health. Various cultivars of oil-bearing plants are grown worldwide, and the chemical compositions of different plant oils are diverse. The extremely complex components in oils lead to diverse standards for evaluating the quality and safety of different EPOs. The environment poses great challenges to the EPO safety and quality during the entire industrial chain, including plant cultivation, harvesting, oil processing, and storage. Environmental risk factors include heavy metal or pesticide residue pollution, insect or harmful microbial infestation, and rancidity. Here, the diverse components in oil and various oil-producing processes are discussed, including plant species, oil yield, and composition complexity, environmental factors that degrade oil quality. Additionally, we propose a whole-industrialchain monitoring system instead of current single-link-monitoring approach by monitoring and tracking the quality and safety of EPOs during the entire process of plant cultivation, raw materials harvest, oil process, and EPOs storage. This will provide guidance for monitoring the quality and safety of EPOs, which were challenged by the deteriorating environment.

“…To understand how the dynamic changes in fatty acid components during cottonseed development are regulated, we generated seed transcriptome profiles using RNA-Sequencing (RNA-seq). RNA-seq libraries were generated from 12 different developmental time points (5,10,15,20,25,30,35,40,45,50, 55 and 60 DPA) and sequenced. A total of~599 million raw reads were generated.…”

“…From health perspective, SFAs may increase the risk of cardiovascular diseases [1][2][3][4]. Polyunsaturated fatty acids (PUFAs), e. g. linoleic acid (C18: 2n-6) and linolenic acid (C18:3n-3), are beneficial to human health, but they are easily oxidized and become rancid when exposed to oxygen under general storage conditions [4][5][6][7]. Chemical hydrogenation of PUFAs can improve the oxidation stability of oil, but unfortunately, it produces harmful trans fatty acids as by-products [8,9].…”

Background Cottonseed is one of the major sources of vegetable oil. Analysis of the dynamic changes of fatty acid components and the genes regulating the composition of fatty acids of cottonseed oil is of great significance for understanding the biological processes underlying biosynthesis of fatty acids and for genetic improving the oil nutritional qualities. Results In this study, we investigated the dynamic relationship of 13 fatty acid components at 12 developmental time points of cottonseed (Gossypium hirsutum L.) and generated cottonseed transcriptome of the 12 time points. At 5–15 day post anthesis (DPA), the contents of polyunsaturated linolenic acid (C18:3n-3) and saturated stearic acid (C18:0) were higher, while linoleic acid (C18:2n-6) was mainly synthesized after 15 DPA. Using 5 DPA as a reference, 15,647 non-redundant differentially expressed genes were identified in 10–60 DPA cottonseed. Co-expression gene network analysis identified six modules containing 3275 genes significantly associated with middle-late seed developmental stages and enriched with genes related to the linoleic acid metabolic pathway and α-linolenic acid metabolism. Genes (Gh_D03G0588 and Gh_A02G1788) encoding stearoyl-ACP desaturase were identified as hub genes and significantly up-regulated at 25 DPA. They seemed to play a decisive role in determining the ratio of saturated fatty acids to unsaturated fatty acids. FAD2 genes (Gh_A13G1850 and Gh_D13G2238) were highly expressed at 25–50 DPA, eventually leading to the high content of C18:2n-6 in cottonseed. The content of C18:3n-3 was significantly decreased from 5 DPA (7.44%) to 25 DPA (0.11%) and correlated with the expression characteristics of Gh_A09G0848 and Gh_D09G0870. Conclusions These results contribute to our understanding on the relationship between the accumulation pattern of fatty acid components and the expression characteristics of key genes involved in fatty acid biosynthesis during the entire period of cottonseed development.

“…The TAG composition of buriti oil was analyzed by reversed-phase HPLC, following the method described by Holčapek et al (14) and adapted by Carvalho et al (15). The chromatographic peaks of the samples were compared with the retention times of chromatographic peaks of soybean oil, which was used as a reference sample (16) and identified based on the expected elution order (considering that retention is increased), and on the fatty acid composition of the samples that were used as a reference.…”

Research background. Extracted from the pulp of an Amazonian fruit, buriti oil is rich in micronutrients with antioxidant properties and has high biological value. The few studies available indicate that this oil could be used in a wide range of applications; however, there are no studies that work on the improvement in the characteristics of this oilfor commercial application. The enzymatic interesterification is one of the tools available to improve the properties of oils and fats and our recent studies demonstrated that the lipase could specifically act on buriti oil to produce structured lipids rich in oleic acid, while preserving most of minority compounds present in this oil. Still looking for ways to expand applicability of this raw oil, in this recent work, we are interested in studying how is the behavior of this structured oil in nanostructured lipid carriers (NLCs). Experimental approach. Samples were stored at 4 and 25 °C for 30 days and their physicochemical properties were evaluated. Results and conclusions. The results showed that the interesterification formed more unsaturated triacylglycerols (TAGs) and NLCs prepared with interesterified buriti oil presented small droplets than NLCs with original buriti oil. Particles remained stable throughout the storage period and NLCs exhibited complex polymorphism with the presence of three crystalline forms. The ORAC value was approximately 23 % higher in nanolipid carries with structured lipids in comparison with the nano lipid carriers with original buriti oil, and the FRAP value, 16 % higher, demonstrating the influence of interesterification on the antioxidant activity of nanocarriers. Thus, NLCs prepared with interesterified buriti oil exhibit smaller droplets, high stability and antioxidant capacity and have potential for nutritional and biological applications. Novelty and scientific contribution. This research showed that interesterification positively influenced the physicochemical properties of NLCs, producing oils rich in oleic acid, high stability and antioxidant capacity. Therefore, it may be interesting to use these nanocarriers to obtain efficient carrier systems for future applications.
