Item Aplicación de la espectroscopia de infrarrojo cercano (NIRS) en productos cárnicos(Universidad Santiago de Cali, 2024) Rosero Martínez, José Miguel; Castro Narváez, Sandra Patricia (Director)An approximation is made to near infrared spectroscopy (NIRS) as a tool for evaluating the quality and authenticity of meat products. Given the growing demand for organic meat products and the need to guarantee their integrity, NIRS stands out as an effective alternative to traditional methods. The methodology employed included literature review, data analysis and method comparison, highlighting the importance of developing more robust calibration and standardization techniques. Quality parameters that NIRS can assess, such as moisture, fat, protein, color and pH, were identified, demonstrating its ability to provide rapid and non-destructive results. Comparison between NIRS and traditional techniques such as proximate analysis revealed that NIRS offers significant advantages in terms of speed and reduced need for sample preparation. However, limitations have been identified, including the need for specific calibrations for each type of meat and the dependence on the quality of the equipment used. Recommendations include advancing the development of calibration techniques and exploring the integration of NIRS technology in real-time computing environments.Item Evaluación de calidad, infestaciones e identificación de componentes en cítricos mediante espectroscopia de infrarrojo cercano (NIRS)(Universidad Santiago de Cali, 2024) Díaz Hurtado, Karol Lisbeth; Castro Narváez, Sandra Patricia (Director)Near infrared spectroscopy (NIRS) has established itself as a crucial technology in modern agriculture, especially for citrus evaluation. This article reviewed and compared recent studies on the application of NIRS in citrus fruit quality assessment, infestation detection, and chemical component identification. The methodology employed includes the analysis of various NIRS techniques, such as reflectance and Fourier transform spectroscopy (FT-NIR), applied in different equipment and wavelength ranges. The results show that reflectance and FT-NIR techniques provide high accuracy in the evaluation of quality parameters such as soluble solids, titratable acidity, and fruit maturity and require methods validated by multivariate models. NIRS allows identification of pests not visible to the naked eye and in the determination of bioactive components such as flavonoids and organic acids, offering rapid and non-destructive evaluations, has the potential to optimize the citrus supply chain, improving product quality and facilitating real- time monitoring.
