The Impact

The consumption of vegetable oil is an important way for the body to obtain tocols. However, the impact of oil types and grades on the tocopherol and tocotrienol contents in vegetable oils is unclear. In this study, nine types of traditional edible oils and ten types of self-produced new types of vegetable oil were used to analyze eight kinds of tocols. The results showed that the oil types exerted a great impact on the tocol content of traditional edible oils. Soybean oils, corn oils, and rapeseed oils all could be well distinguished from sunflower oils. Both sunflower oils and cotton seed oils showed major differences from camellia oils as well as sesame oils. Among them, rice bran oils contained the most abundant types of tocols. New types of oil, especially sacha inchi oil, have provided a new approach to obtaining oils with a high tocol content. Oil refinement leads to the loss of tocols in vegetable oil, and the degree of oil refinement determines the oil grade. However, the oil grade could not imply the final tocol content in oil from market. This study could be beneficial for the oil industry and dietary nutrition.

Background. In recent years, requirements for the properties of lubricants and their components are increasing. Attention is paid to the impact of lubricants on the environment. Urea greases fully meet the high requirements for the properties of lubricants. The development of greases of this class and vegetable oil-based additives should solve the environmental problems of their use. Objective. The purpose of the paper is development of urea greases and their components using raw materials of plant origin. Methods. A number of protective additives to lubricants were obtained by epoxidation of vegetable oils and introduction of nitrogen-containing fragments on the carbonyl group and epoxy ring. Amidation of triacylglycerides of vegetable oils with ethylenediamine synthesized monoaminoamides of fatty acids of linear structure. Urea thixotropic systems are synthesized by the interaction of polyisocyanate with fatty acid monoaminoamides in petroleum oil. Synthesized additives in various quantities were introduced into the composition of the investigated products in order to check the operational properties of the finished greases. Results. The obtained greases are characterized by a high level of mechanical and colloidal stability. Their composition and chemical structure were established by a set of spectrometric methods of analysis. The upper temperature limit of application of the synthesized urea in the range of 150–200 °С is established by the method of derivatographic analysis. It is established that the combination of urea thickener and vegetable oil-based additives allows obtaining urea greases with high thermal stability, improved protective and antioxidant characteristics. The use of environmentally friendly oleochemical products in the composition of the thickener and lubricant additives improves the biodegradability of the developed grease composition. Conclusions. It is shown that the proposed series of vegetable oil transformations allows obtaining ready-made compositions of urea greases and their components using raw materials of natural origin. The obtained products have satisfactory operational properties and according to some indicators industrial analogues prevail. This allows us to recommend the developed urea oils as substitutes for commercial products.

The use of cutting fluids has played a vital role in machining operations in lubrication and cooling. Most cutting fluids are mineral oil-based products that are hazardous to the environment and the worker, cause severe diseases and pollute the environment. In addition, petroleum resources are becoming increasingly unsustainable. Due to environmental and health issues, legislations have been established to ensure that the consumption of mineral oil is reduced. Consequently, researchers are making efforts to replace these mineral oil-based products. Vegetable oils are grasping attention due to their better lubricating properties, ease of availability, biodegradability, low prices, and non-toxicity. In this study, a detailed review and critical analysis are conducted of the research works involving vegetable oils as cutting fluids keeping in view the shortcomings and possible solutions to overcome these drawbacks. The purpose of the review is to emphasise the benefits of vegetable oil-based cutting fluids exhibiting comparable performance to that of mineral oil-based products. In addition, an appropriate selection of non-edible vegetable oil-based cutting fluids along with optimum cutting parameters to avoid a scanty supply of edible oils is also discussed. According to this research, vegetable oils are capable of substituting synthetic cutting fluids, and this option might aid in the successful and cost-efficient implementation of green machining.

Petroleum activities have caused great concern due to the impact of major contamination it and its composites havecaused to nature, mainly to aquatic environments. Among the physical, chemical and biological methods available toremediate wastewater contaminated with hydrocarbons bioremediation is considered an environment-friendly and relativelycost-effective technology. That is due to the biodegradation the process is based on, using microbial populationsin the contaminated environment remediation. The objective of this study was to assess biodegradation in contaminatedaqueous media contamined by automotive lubricant oils and vegetable oils using respirometry technique. The Bartha andPramer’s respirometric method promotes CO2 quantification in the respirometers. The used lubricant oil had higher CO2production and the used vegetable oil was more biodegradable than the still unused vegetable oil. However, these vegetableoils were less biodegraded due to the presence of TBHQ preservative in their composition, thus causing a reductionin CO2 production. Thus, an environmental behavior analysis of lubricant and vegetable oils is important to provide newstrategies in treating contaminated environments.

The development of the economic situation in Russia in recent years is characterized by the achievement of stabilization at the macro level, the strengthening of investment activity, the expansion of the scope of activities of the processing industry, the strengthening of public confidence in domestic goods and finished products. The research urgency is caused by the fact that in Russia economic competition becomes more acute in oil and fat processing sector, also has a problem of lack of training organizations to consider the impact of external factors and competitive advantages of the industry to ensure financial stability. The purpose of the study is to study the features of factors affecting the competitiveness of the oil processing complex. On the basis of sources of economic literature, the authors studied the competitiveness of vegetable oil production by comparison and identified the problems of insufficient methodological support for studying the impact of factors that determine the current state of the vegetable oil market, methods and approaches for assessing the competitiveness of organizations. The leading direction is a comprehensive approach presented by the authors in the article, including the study of domestic and international experience in determining the factors of internal and external environment that affect the development of the industry. The study of the traditional system of assessing the competitiveness of vegetable oils is given, proposed by Russian and foreign scientists. As a result of the conducted research it is established that modern domestic and foreign methods of the analysis of the competitiveness of vegetable oils do not differ in high quality and have shortcomings. The authors noted that the analysis of the concept of competitiveness of vegetable oils does not take into account the quality indicators are not always fully represented the composition and structure of the concept, not justified organizational and methodological approaches to the analysis of the concept of competitiveness applicable to vegetable oils. The researchers note the need for an objective assessment of the analysis of the concept of competitiveness of vegetable oils to supplement it with a more detailed study of improving the level of competitiveness. In their opinion, the lack of a single definition of the term "competitiveness of products" is one of the most difficult in the formation of an adequate approach to the assessment of the phenomenon. This leads to the fact that the most common assessment is a comparative assessment of similar vegetable oils with ethanol. The study conducted by the authors has scientific and practical significance and will allow to develop a methodological apparatus (parameters and criteria for assessing the level of competitiveness of vegetable oils) in accordance with the requirements of the industry in the world economy, as well as to form a set of strategic and tactical management decisions to improve the competitiveness of vegetable oils and mechanisms of interaction in creating competitive advantages and strengthening the market position of vegetable oils.

The Western diet is characterized by a high consumption of heat-treated fats and oils. During deep-frying processes, vegetable oils are subjected to high temperatures which result in the formation of lipid peroxidation products. Dietary intake of oxidized vegetable oils has been associated with various biological effects, whereas knowledge about the effects of structurally-characterized lipid peroxidation products and their possible absorption into the body is scarce. This study investigates the impact of linoleic acid, one of the most abundant polyunsaturated fatty acids in vegetable oils, and its primary and secondary peroxidation products, 13-HpODE and hexanal, on genomic and metabolomic pathways in human gastric cells (HGT-1) in culture. The genomic and metabolomic approach was preceded by an up-to-six-hour exposure study applying 100 µM of each test compound to the apical compartment in order to quantitate the compounds’ recovery at the basolateral side. Exposure of HGT-1 cells to either 100 µM linoleic acid or 100 µM 13-HpODE resulted in the formation of approximately 1 µM of the corresponding hydroxy fatty acid, 13-HODE, in the basolateral compartment, whereas a mean concentration of 0.20 ± 0.13 µM hexanal was quantitated after an equivalent application of 100 µM hexanal. An integrated genomic and metabolomic pathway analysis revealed an impact of the linoleic acid peroxidation products, 13-HpODE and hexanal, primarily on pathways related to amino acid biosynthesis (p < 0.05), indicating that peroxidation of linoleic acid plays an important role in the regulation of intracellular amino acid biosynthesis.

Vegetable oils are being considered as the potential replacements to mineral oils because of their better natural execution and for their high fire point. In spite of the fact that these fluids have been utilized as a part of appropriation transformers, it is as yet a huge advance to receive vegetable oils in control transformer because of high cost and abnormal state of well being and unwavering quality required in benefit for these units. Vegetable oils such as honge oil (HO), neem oil (NO), mustard oil (MO), punna oil (PO) and castor oil (CO) offer the reasonable option for mineral oil. It is expected that the greater part of the un-matured oil could fulfil the base necessity of dielectric protection fluids in the transformer. This paper concentrated on the impact of maturing on the electrical and physicochemical properties of HO, NO, MO, PO and CO. Fixed maturing tests have been set at 90°C for 30 days, 60 days and 90 days. Prior to the maturing procedure, the examples were dried in a vacuum broiler under the pressure of 0.8kPa at 85°C for 48 hours keeping in mind the end goal to evacuate the dampness content in the oils. At that point, the oils were impregnated with the Nomex paper and keep on ageing for choosing the span time. The electrical properties (relative permittivity, dielectric misfortunes, resistivity and breakdown quality), mechanical properties (thickness and elasticity) and substance properties (dampness and corrosiveness) of the oils were estimated all through the maturing time frames. It can be reasoned that the research center quickened warm maturing test uncovers that every single vegetable oil in this examination are safe towards oxidation in light of the steady thickness and low corrosiveness estimations of vegetable oils all through the maturing term even with the nearness of oxygen. The AC breakdown voltages of vegetable oils can in any case conform to the prescribed furthest reaches of new Vegetable oil set by ASTM 6781 even after subjected to maturing. From the results, it may be concluded that the proposed vegetable oils can be used as the alternatives for mineral oil.

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.
