Abstract EN
Consumers must be assured that bought food supplements contain both bilberry extract and the anthocyanin amounts that match the declared levels.
Therefore, a Fourier transform near-infrared (FT-NIR) spectroscopic method was validated based on principal component scores for the prediction of bilberry extract adulteration and partial least squares regression model for total anthocyanin evaluation.
Anthocyanins have been quantified individually in 71 commercial bilberry extracts by HPLC-DAD, and 6 of them were counterfeit.
The anthocyanin content in bilberry extracts was in the range 18–34%.
Authentic bilberry extracts (n=65) were divided into two parts: one for calibration (n=38) and the other for the validation set (n=27).
Spectra were recorded in the range of 4000–12500 cm−1, and a good prediction model was obtained in the range of 9400–6096 and 5456–4248 cm−1 with r2 of 99.5% and a root-mean-square error of 0.3%.
The adulterated extracts subjected to NIR analysis were recognized as noncompliant, thus confirming the results obtained by chromatography.
The FT-NIR spectroscopy is an economic, powerful, and fast methodology for the detection of adulteration and quantification of the total anthocyanin in bilberry extracts; above all, it is a rapid, low cost, and nondestructive technique for routine analysis.
