Determination of saffron adulteration thorough the package using Vis-NIR hyperspectral imaging and chemometric techniques |
|
| چکیده انگلیسی مقاله |
in recent decade as a reliable tool for food authenticity. This technique combines spectroscopy and imaging techniques, enabling the acquisition of hyperspectral images. These images are composed of reflectance pixel maps containing hundreds of channels, one per wavelength [3]. The objective of the present study was combination of Vis-NIR HSI with chemometric techniques for saffron authentication and adulteration detection (safflower, calendula and style) in intact form thorough the package. Three different packages of thin and thick plastic envelope and poly-crystal were tested. For this purpose, HSI images of 38 intact authentic saffron samples were recorded in spectral range 400-950 nm. Then, multivariate curve resolution-alternating least squares (MCR-ALS) was used for obtaining pure spatial and spectral profiles of the components and then, principal component analysis (PCA) was applied to the resolved spatial profiles of saffron to find possible patterns of authentic samples. Partial least squares-discriminant analysis (PLS-DA) algorithm was used for the classification of MCR-ALS resolved spatial profiles of saffron. |
