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.

The zero-waste biorefinery concept inspired a green oleo-extraction of both natural volatile (e.g., borneol, camphor, o-cymene, eucalyptol, limonene, α-pinene, and terpinen-4-ol) and non-volatile (e.g., carnosol, carnosic, and rosmarinic acid) bioactive compounds from rosemary leaves with vegetable oils and their amphiphilic derivatives as simple food-grade solvents. It is noteworthy that soybean oil could obtain the highest total phenolic compounds (TPCs) among 12 refined oils including grapeseed, rapeseed, peanut, sunflower, olive, avocado, almond, apricot, corn, wheat germ, and hazelnut oils. Furthermore, the addition of oil derivatives to soybean oils, such as glyceryl monooleate (GMO), glyceryl monostearate (GMS), diglycerides, and soy lecithin in particular, could not only significantly enhance the oleo-extraction of non-volatile antioxidants by 66.7% approximately, but also help to remarkably improve the solvation of volatile aroma compounds (VACs) by 16% in refined soybean oils. These experimental results were in good consistency with their relative solubilities predicted by the more sophisticated COSMO-RS (COnductor like Screening MOdel for Real Solvents) simulation. This simple procedure of using vegetable oils and their derivatives as bio-based solvents for simultaneously improving the extraction yield of natural antioxidants and flavors from rosemary showed its great potential in up-scaling with the integration of green techniques (ultrasound, microwave, etc.) for zero-waste biorefinery from biomass waste to high value-added extracts in future functional food and cosmetic applications.

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.

Advanced research on vegetable oils as gear lubricants became a topic of interest in green technology where natural resources could be appliedin transportation and industry. The main objectives are to meet demand and monitor the impact of human involvement. Many researches have suggested that vegetable oil has the potential as an alternative lubricant for many engineering process although it has some disadvantages such as oxidative instability and poor properties at low temperature. The use of vegetable oils as a helical gear lubricant has not been studied before. This study is to experimentally analyse the performance of sunflower oil and soybean oil as gear lubricants. An oil test data was taken periodically from the gear test rig within 80 consecutive hours. The performance of sunflower and soybean oils were analysed based on lubricant properties such as kinematic viscosity and viscosity index. The experimental data was compared to the ideal performance of a synthetic gear lubricant. The findings show that sunflower oil has better lubricant properties compared to soybean oil. Sunflower oil shows appreciable high temperature properties as synthetic gear lubricant.

ABSTRACT Polymerized soybean oils of different molecular weights were used as plasticizers in NR/SBR compositions. The oils of different molecular weights and viscosities were synthesized by cationic polymerization using a proprietary technology. Because vegetable oils have double bonds, they are not only viscosity depressants but also active participants in cross-linking reactions. Properties of elastomers extended with different concentrations of mineral oil or pure soybean oil were compared with elastomers extended by polymerized oils of different molecular weights at the same concentrations. It was found that polymerized soybean oil could be substituted for naphthenic process oil with minimal differences in mechanical and dynamic properties.
