“…All pollen samples spectra have bands at 2920 cm −1 that could be associated to the C-H stretching of carbohydrates (Anjos et al, 2015;Gallardo-Velázquez et al, 2009) in aliphatic structures, such as fatty acids and other long-chain structures like carboxylic acids (Elhajjouji et al, 2007;Movasaghi, Rehman, & ur Rehman, 2008). In fact, for the calibration model obtained for carbohydrates there wereonly bands on the region between 3007 and 2746 cm −1 .…”

Bee pollen contains almost all nutrients required by the human organism as well as diverse health-promoting substances. However, its composition and nutritional value greatly depend on the botanical origin. As such, it is important to develop a rapid and non-expensive methodology that allows studying its characteristics, making labelling more objective and easier. The FTIR-ATR technique was used to predict some nutritional parameters in 126 bee pollen samples. FTIR-ATR spectrum obtained in the region between 4000 and 400 cm −1 with PLS Regression models were used to correlate spectral information with the data obtained using reference methods. In this first approach with pollen samples, good correlation models with appropriate accuracy were obtained for the evaluated parameters with r 2 varying from 74.8 to 97% and residual prediction deviation between 2.0 and 5.8. These results suggest that FTIR-ATR may be a useful technique for assessing bee pollen's composition.Aplicació n de la espectroscopía FTIR-ATR a la caracterizació n del polen de abeja El polen de abeja contiene casi todos los nutrientes requeridos por el organismo humano, así como diversas sustancias promotoras de la salud. Sin embargo, su composició n y valor nutricional dependen en gran medida del origen botánico. Como tal, es importante desarrollar una metodología rápida y econó mica que permita estudiar sus características, haciendo el etiquetado más objetivo y más fácil. La técnica FTIR-ATR se utilizó para predecir algunos parámetros nutricionales en 126 muestras de polen de abeja. Se utilizó el espectro FTIR-ATR obtenido en la regió n entre 4000 y 400 cm-1 con modelos de regresió n PLS para correlacionar informació n espectral con los datos obtenidos usando métodos de referencia. En este primer abordaje con muestras de polen, se obtuvieron buenos modelos de correlació n con una precisió n adecuada para los parámetros evaluados con r2 variando de 74,8% a 97% y una desviació n de predicció n residual entre 2,0 y 5,8. Estos resultados sugieren que el FTIR-ATR puede ser una técnica útil para evaluar la composició n del polen de abeja.

“…The potential of this rapid, low cost, and reliable technique, which requires little or no sample preparation, was also studied in determination of the botanical origin of honey (76)(77)(78). The possibility to differentiate 130 Serbian unifloral honey samples (lime, acacia, and sunflower) according to their botanical origin using attenuated total reflectance infrared spectroscopy (ATR-IR) was investigated (79).…”

Food authenticity in a broader sense means fulfilling chemical and physical criteria prescribed by the proposed legislation. In the case of honey authenticity, two aspects are of major concern: the manufacturing process and the labelling of final products in terms of their geographical and botanical origin. A reliable assessment of honey authenticity has been a longterm preoccupation of chemists-analysts and it usually involves the use of several criteria and chemical markers, as well as a combination of analytical and statistical (chemometric) methods. This paper provides an overview of different criteria and modern methods for the assessment of honey authenticity in the case of a statistically significant number of authentic honey samples of several botanical types from various regions of Serbia.

“…It has the advantages of short measurement time, high accuracy, non-destructive testing and continuous determination. Fourier transform infrared spectroscopy (FTIR) and attenuated total reflection (ATR) infrared spectroscopy [1][2][3][4] have wide application in the measurement of the quality of agricultural products and food [5][6][7][8][9][10], cell metabolism measurement [5], and enzyme activity analysis [6]. For example, data from FTIR/ATR could quantify corn syrup, high fructose syrup, and inverted sugar in Mexican honey when optimal calibrations were performed with partial least squares (PLS) [7].…”

Abstract-The rapid quantification method of human serum glucose was established by using the Fourier transform infrared spectroscopy (FTIR) and attenuated total reflection (ATR). Based on the optimal predicting effect, a subtraction band model combining with optimal single continuous wave band was developed. The spectrum (1600-900 cm −1 ) was selected as the base band. Then, window subtracted partial least squares (WSPLS) based on the spectrum was carried out, and the optimal two continuous bands were found. The results show that the prediction effect of the base band model is obviously better than that of the whole spectral model, and WSPLS model is even better than base band model. Finally, an independent test set was tested for model verification. V-SEP and V-R P were 0.831 mmol/L and 0.882, respectively by the compensation model.
