<\/a><\/p>\nPopular worldwide, essential oils are raw materials with different properties and can be used in different ways, depending on the desired benefit. Researchers from the Federal University of Santa Maria (UFSM) in partnership with the Integrated Regional University of Alto Uruguai and Miss\u00f5es (URI) developed a method using a smartphone that allows capturing color changes from a reaction carried out with the majority component of clove essential oil, the substance eugenol. The commercial value of this essential oil is often dependent on the concentration of this substance. The results of the research were published in the article <\/span>Fast and low-cost method using a smartphone for the determination of eugenol in clove essential oil<\/span><\/a>, in the journal <\/span>Ci\u00eancia Rural<\/span><\/i> (vol. 53, n.\u00ba 10).<\/span><\/p>\n During the research, scientists used 2 mL disposable vials for evaluations regarding the experimental variables of analysis with a smartphone, such as luminosity, for example, where a freely accessible application was used to capture and process the data. Different lighting conditions were evaluated for capturing images, and, to achieve the objectives, individual results were compared with each other.\u00a0<\/span><\/p>\n Image: Pixabay.<\/p><\/div>\n The results obtained showed the feasibility of using smartphones for this task, with performance comparable to instrumental methods used in dedicated laboratories, such as gas chromatography and spectrophotometry. \u201cBased on our research, we can consider that quality control of essential oils can be carried out quickly, at low cost and with portable instrumentation, allowing the dissemination of knowledge and access to data previously impossible to be generated outside the environment laboratory\u201d, explains researcher Juliano S. Barin.<\/span><\/p>\n According to Juliano, the results can encourage the use of this tool by several people, allowing even small producers who lack a laboratory infrastructure to evaluate their products to carry out quality control. \u201cThis research takes another step towards the popularization of science, where devices present in people’s daily lives can be repurposed to carry out chemical analyzes that can be used to control the quality of natural products. Features such as portability, low cost and easy operation allow the use of the technology by non-specialized people, which guarantees access to quality control for practically anyone\u201d, he concluded.<\/span><\/p>\n SANTOS, I.C., et al.
