Item Aplicación de la espectroscopia en el infrarrojo cercano (NIRS), en el análisis de aceites esenciales para aplicación industrial (cosmética y farmacéutica): Revisión sistemática(Universidad Santiago de Cali, 2024) Vasquez Obando, Sergio; Orduña Ortega, Julieth (Directora); Vargas, Yaneth (Directora)This review presents the application of Near Infrared Spectroscopy (NIR) in the analysis of essential oils, specifically in the cosmetic, pharmaceutical and phytotherapeutic industries. This is a vibrational technique that uses light in the range of 780 to 2500 nm, allowing the qualitative and quantitative evaluation of biological samples. Among the most notable advantages are the minimal sample preparation and the ability to perform rapid and noninvasive analysis, however, the low sensitivity and complexity in the interpretation of spectra is a major disadvantage. The article highlights the use of NIR in quality control and in determining the chemical composition of essential oils, which are obtained by various extraction methods. The NIR technique is effective in identifying the purity and taxonomy of essential oils and in quantifying specific compounds such as terpenes. The present review also mentions the growing interest in essential oils due to their antioxidant and antimicrobial properties, and their use in natural and safe products compared to synthetic antioxidants. In the pharmaceutical industry, NIR could be used in the analysis of compounds in the pharmaceutical industry, while in the cosmetic industry, it could verify lipid oxidation and emulsion quality. NIR spectroscopy is a great tool in the analysis of essential oils, as it offers an efficient and accurate method to ensure the quality and safety of products in the cosmetic and pharmaceutical industries.
