“…This is because the steel adsorbed several substances from the extract. In both cases, some bands correspond to hydroxy-phenolic groups (3336.4 cm −1 ), aromatic groups (1653.94 cm −1 ), groups that, according to the literature, are the ones that improve corrosion inhibition [ 6 , 20 , 21 , 22 ]. On the other hand, changes in the intensities of some peaks of the extract were observed once applied to the steel.…”

In this work, the production of a novel methodology for the application of natural corrosion inhibitors on steel, using an autoclave is presented. Tests were carried out using Artemisia vulgaris. The inhibitor was produced with a simple soxhlet extraction process using 15 g of Artemisia vulgaris and 260 mL of Ether. Once the inhibitor was produced, the steel was immersed in it, to form a coating that protects the material against corrosion. Thermogravimetry analyzes (TGA) were performed on the inhibitor, to determine the degradation temperature; it was observed that, at 321 °C, the loss of organic mass begins. After applying the inhibitor to the steel, the Fourier Transform Infrared Spectroscopy (FTIR) technique was used to determine the vibrational bands and the difference between the spectra for the steels before and after the coating was applied. For the evaluation of the method efficiency, Electrochemical Impedance Spectroscopy (EIS) and polarization resistance tests were performed, where Nyquist diagrams and Tafel curves were obtained, for steels with and without treatment. In this case, an increase of 93% in the corrosion resistance, and an 88% decrease in the corrosion rate were observed, proving that this methodology can be used to protect steel against corrosion and extend the steel’s useful life.

“…Through a variety of algorithms, the key contributing variables are identified and weighted such that the wavelengths most closely correlated with the analyte concentration have the greatest contribution to the PLS model [ 28 ]. PLS regression is widely used for the development of IR spectroscopy models across the food science sector [ 29 , 30 , 31 ].…”

The Use of Infrared Spectroscopy for the Quantification of Bioactive Compounds in Food: A Review

et al. 2023

View full text Add to dashboard Cite

Infrared spectroscopy (wavelengths ranging from 750–25,000 nm) offers a rapid means of assessing the chemical composition of a wide range of sample types, both for qualitative and quantitative analyses. Its use in the food industry has increased significantly over the past five decades and it is now an accepted analytical technique for the routine analysis of certain analytes. Furthermore, it is commonly used for routine screening and quality control purposes in numerous industry settings, albeit not typically for the analysis of bioactive compounds. Using the Scopus database, a systematic search of literature of the five years between 2016 and 2020 identified 45 studies using near-infrared and 17 studies using mid-infrared spectroscopy for the quantification of bioactive compounds in food products. The most common bioactive compounds assessed were polyphenols, anthocyanins, carotenoids and ascorbic acid. Numerous factors affect the accuracy of the developed model, including the analyte class and concentration, matrix type, instrument geometry, wavelength selection and spectral processing/pre-processing methods. Additionally, only a few studies were validated on independently sourced samples. Nevertheless, the results demonstrate some promise of infrared spectroscopy for the rapid estimation of a wide range of bioactive compounds in food matrices.

Se evaluó en tomate verde el efecto de la adición de bocashi o estiércol de ovino mezclado con 50% de fertilizantes sintéticos. Se estudiaron variables fisiológicas, de producción de biomasa, rendimiento de fruto y contenido de minerales en el follaje, valor nutritivo y capacidad antioxidante del fruto. La biomasa y rendimiento de fruto no presentaron diferencias entre tratamientos, excepto la biomasa de raíz. La acumulación de N fue mayor en el follaje de plantas con estiércol de ovino + fertilización química 50% (EO-FQ 50%), la tasa de transpiración fue mayor y la conductancia estomática menor. La acumulación de P y K no varió entre tratamientos. Los contenidos de grasa, Ca, K, Fe y fenoles totales fueron mayores en frutos con EO-FQ 50%. La adición de abono orgánico con fertilización química al 50% iguala los rendimientos y mejora la calidad de fruto de tomate verde (P. ixocarpa). Palabras clave: bocashi, ovinasa, Physalis ixocarpa, calidad de fruto, antioxidantes.
