Laser-Induced Breakdown Spectroscopy: An Efficient Tool for Food Science and Technology (from the Analysis of Martian Rocks to the Analysis of Olive Oil, Honey, Milk, and Other Natural Earth Products)

Abstract

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.

Honey Quality and Microplastic Migration from Food Packaging: A Potential Threat for Consumer Health?

“…Recently, food analyses, especially honey characterization, are mostly successful through Raman [31] and FTIR [30] analyses, laser-induced breakdown spectroscopy [124], photoacoustic spectroscopy [32], and general optical spectroscopy methods, often combined with a multivariate statistical analysis [33]. FTIR has been used mainly for water content measurements and sugar (fructose and glucose) identification in honey [26,27].…”

A novel strategy for quantitative analysis of the energy value of milk powdervialaser-induced breakdown spectroscopy coupled with machine learning and a genetic algorithm

“…Laser-induced breakdown spectroscopy (LIBS) is a rapidly developing chemical element analysis technology that has been widely used in the detection of alloys, [5][6][7] plant materials, [8][9][10] food and nutrition, [11][12][13] rocks, [14][15][16] and soils. [17][18][19] As a fast, online, pollution-free, and low-cost technology, it is well suited for the approximate analysis of milk powder.…”

Rapid Authentication and Detection of Olive Oil Adulteration Using Laser-Induced Breakdown Spectroscopy

“…Besides the experimental simplicity of LIBS, its main attributes are minimum or no sample preparation and its ability to be applied to samples of all states (solid, liquid, and gas), whether dielectric or not [8,9]; it can also provide rapid, in-situ, online, and real-time measurements. Due to these advantages, LIBS has been proposed for a wide range of applications, such as industrial [10], environmental/recycling [11,12], cultural heritage [13,14], food analysis [15,16], etc.…”
