“…Recently, a challenging application of LIBS that received considerable attention is the implementation of LIBS for foodstuff analysis. Specifically, LIBS was employed for the detection of heavy metals in various foodstuffs, for the detection of adulteration and for determining the designation of origin for various types of foodstuffs [ 15 , 16 ]. In particular, during the last decade, more than 100 scientific articles have been published that cover various aspects of LIBS applications in food related analysis.…”

Laser-Induced Breakdown Spectroscopy (LIBS), having reached a level of maturity during the last few years, is generally considered as a very powerful and efficient analytical tool, and it has been proposed for a broad range of applications, extending from space exploration down to terrestrial applications, from cultural heritage to food science and security. Over the last decade, there has been a rapidly growing sub-field concerning the application of LIBS for food analysis, safety, and security, which along with the implementation of machine learning and chemometric algorithms opens new perspectives and possibilities. The present review intends to provide a short overview of the current state-of-the-art research activities concerning the application of LIBS for the analysis of foodstuffs, with the emphasis given to olive oil, honey, and milk.

“…In contrast, low-cost LIBS systems have received great attention and expanding the applicability of the technique. [29][30] The low sensitivity and spectral resolution of these instruments have been circumvented by using some simple devices to increase the sensitivity and applying different spectral processing to extract the appropriate analytical information. [30][31][32] In this work, a low-cost LIBS system coupled with a sparkdischarge (SD) for authentication of the geographical origin of honey was evaluated, taking advantage of the speed and reliability of the LIBS and aiming to provide an accessible device for authentication and traceability of honey.…”

Honey is a natural food that is valued worldwide for its nutritional and therapeutic values. Therefore, authentication of honey based on geographical origin is a guarantee of its genuine properties of honey. In this article, an evaluation of spark discharge-assisted laser-induced breakdown spectroscopy (SD-LIBS) for certification of the geographical origin of honey is reported. Forty-nine samples of multifloral honey produced in four Argentine provinces were considered. The results showed that best classification performance was obtained using smoothing, generalized least squares weighting (GLSW) and mean centering for spectral preprocessing, added to the k-nearest neighbor (k-NN) or Support Vector Machine (SVM) classification algorithms, which provided 100% of correct classification. More importantly, the results of Partial Least Squares -Discriminant Analysis (PLS-DA) pointed to N, Ca, K, Cu, Fe and Mn as key elements for the certification of geographical origin. In addition, the best indicator for verification of the source of honey was found to be in the assessment of the amount of N in honey. These findings confirm SD-LIBS as a promising tool for authentication of honey origin and quality, providing a simple, fast and environmentally friendly solution. The method can be useful for industry, the marketplace and other areas related to food authentication.
