Abstract:
... Camellia oil (CAO) is a premium edible vegetable oil with medical value and biological activity, but it is susceptible to adulteration. Therefore, the demand for intelligent analysis to decipher the category and proportion of adulterated oil in CAO was the main driver of this work. Excitation-emission matrix fluorescence (EEMF) spectra of 933 vegetable oil samples were characterized by a chemometr ...

Abstract:
... In this paper, a miniaturized kapok fiber-supported liquid extraction (mini-KF-SLE) method was proposed for selective extraction of pesticide residues in vegetable oils. The natural kapok fiber was used as an inert oil support material based on its hydrophobic and lipophilic properties, and the extraction device was conveniently constructed by loading 15 mg of kapok fiber at the lower middle part ...
... To compare the oxidation products of four types of vegetable oils (palm oil, soybean oil rapeseed oil, and flaxseed oil) during thermal processing, lipidomics, volatolomics and simulation analyses were integrated to investigate the evolution of volatile profiles. The evolution of volatile profiles in different vegetable oils were found to be different, which are attribute to their different lipid ...
... Herein, a modified indirect method was established for the determination of 3-monochloropropane-1,2-diol esters (3-MCPDEs) and glycidyl esters (GEs), employing magnetic solid phase extraction by boronic acid-functionalized magnetic nanoparticles to replace the traditional clean-up procedure. Compared with routine methods, it has been proved to be more sensitive with limits of detection in the rang ...

vegetableoil, etc ; chitosan; emulsions; ethanol; liquids; palm oils; surfactants; zeolites; Show all 8 Subjects
Abstract:
... Microemulsion fuels have involved oil, alcohol, surfactant, and cosurfactant/amphiphilic molecule. A system of chemical reactions takes place between phase boundaries. Palm oil as vegetable oil has been assessed as a renewable resource. So, before applying microemulsions, an immiscible mixture (palm oil and ethanol) needs to be evaluated for the chemical activity, such as suspected defects. This s ...
vegetableoil, etc ; deodorization; evolution; odors; smell; soybean oil; steam; taste; Show all 8 Subjects
Abstract:
... Conventional deodorization for refining vegetable oil involves evaporating volatile molecules by applying high temperatures (240–260 °C) for 2–3 h. It inevitably leads to a degradation of the refined oil quality. The chief volatile compounds from the conventional deodorization process were hydrocarbons, which are not the odor source of the oil. Particularly in the case of crude soybean oil, the ma ...

Abstract:
... As the slow-release fertilizer, oil-coated fertilizer can not only slow down the nutrients loss, but also have outstanding advantages in controlling the nutrients release. Based on a large number of literature, this paper systematically investigated the composition, classification, properties and preparation of oil-coated fertilizers, summarizes the challenges faced by the oil-coated fertilizers a ...
vegetableoil, etc ; castor oil; crosslinking; durability; piperazine; polymers; solvents; thermal stability; Show all 8 Subjects
Abstract:
... The development of castor oil-based polyurethanes has been restricted significantly because they have poor mechanical properties and cannot be reprocessed or recycled owing to their soft backbone combined with irreversible crosslinked structures. Herein, we synthesized novel castor oil derived dynamic polymer networks (DPNs) based on reversible piperazine-urea bonds, which were obtained by reactin ...

Lentilactobacillus parafarraginis FAM-1079, Lactococcus lactis subsp. lactis FAM-17918, and L. lactis subsp. lactis biovar diacetylactis FAM-22003 showed the most efficient formation of targeted δ-lactones. The application of subletha ...

Abstract:
... Previous studies have indicated aquifer heterogeneity has an important influence on the removal of Cr(VI) in groundwater, but little attention is paid to the effects of aquifer heterogeneity during the process especially under conditions like actual groundwater temperature and hydraulic gradient in the field. Thus, in this study, in situ remediation of Cr(VI)-contaminated shallow groundwater in a ...

Abstract:
... Desolventizing is a key process in the vegetable oil industry, aimed at removing residual hexane from solid meals resulting from the extraction stage of crushed oilseeds. Desolventizing takes place industrially in a large and complex piece of equipment called Desolventizer-Toaster, which uses large amounts of energy in the form of direct and indirect steam to strip the solvent adsorbed on the soli ...

Abstract:
... Traditional vegetable oil refining strategies are energy-intensive and can result in substantial oil loss. In metalworking and machine shops, electrostatic “oil cleaners” are used to remove particulate matter (e.g., wear particles, soot, vanish, and dust) from non-polar working fluids with low dielectric constants (e.g., lubricating oil and hydraulic oil). Vegetable oils are also non-polar fluids. ...
