“…The industrial transition to green and sustainable production processes has led to intensive research into alternatives to organic solvent-based processing. In this context, Natural Deep Eutectic Solvents (NADES) have attracted the interest of researchers from a diverse range of different analytical and applications fields [ 35 ], biotechnology [ 36 ], energy [ 37 ], water remediation [ 38 ], food industry [ 39 ], cosmetics and pharmaceutics [ 40 , 41 ], etc. NADES are solvents of great interest in chemistry, due to their unique solvent properties, including high extraction ability for some natural products and high solubilisation strength of a wide range of organic and inorganic compounds [ 35 , 42 , 43 , 44 ].…”

Raman spectroscopy is a label-free, non-destructive, non-invasive analytical tool that provides insight into the molecular composition of samples with minimum or no sample preparation. The increased availability of commercial portable Raman devices presents a potentially easy and convenient analytical solution for day-to-day analysis in laboratories and production lines. However, their performance for highly specific and sensitive analysis applications has not been extensively evaluated. This study performs a direct comparison of such a commercially available, portable Raman system, with a research grade Raman microscope system for the analysis of water content of Natural Deep Eutectic Solvents (NADES). NADES are renewable, biodegradable and easily tunable “green” solvents, outcompeting existing organic solvents for applications in extraction from biomass, biocatalysis, and nanoparticle synthesis. Water content in NADES is, however, a critical parameter, affecting their properties, optimal use and extraction efficiency. In the present study, portable Raman spectroscopy coupled with Partial Least Squares Regression (PLSR) is investigated for rapid determination of water content in NADES samples in situ, i.e., directly in glassware. Three NADES systems, namely Betaine Glycerol (BG), Choline Chloride Glycerol (CCG) and Glucose Glycerol (GG), containing a range of water concentrations between 0% (w/w) and 28.5% (w/w), were studied. The results are directly compared with previously published studies of the same systems, using a research grade Raman microscope. PLSR results demonstrate the reliability of the analysis, surrendering R2 values above 0.99. Root Mean Square Errors Prediction (RMSEP) of 0.6805%, 0.9859% and 1.2907% w/w were found for respectively unknown CCG, BG and GG samples using the portable device compared to 0.4715%, 0.3437% and 0.7409% w/w previously obtained by analysis in quartz cuvettes with a Raman confocal microscope. Despite the relatively higher values of RMSEP observed, the comparison of the percentage of relative errors in the predicted concentration highlights that, overall, the portable device delivers accuracy below 5%. Ultimately, it has been demonstrated that portable Raman spectroscopy enables accurate quantification of water in NADES directly through glass vials without the requirement for sample withdrawal. Such compact instruments provide solvent and consumable free analysis for rapid analysis directly in laboratories and for non-expert users. Portable Raman is a promising approach for high throughput monitoring of water content in NADES that can support the development of new analytical protocols in the field of green chemistry in research and development laboratories but also in the industry as a routine quality control tool.

“…The density will directly impact the viscosity of NaDES, which is a key parameter for transfer operations and extractive capacities [7,32]. Thus, several strategies have been described for lowering the viscosity of NaDES in order to improve their extractive performance and facilitate their use, in particular at the industrial level.…”

“…The addition of a small proportion of water (less than 20%) is a strategy conventionally described for reducing viscosity and improving performance [15,29]. The second most common strategy consists in carrying out all the extraction and transfer operations while maintaining a high temperature, generally between 50 and 70 • C [7,32].…”

“…The use of NaDES in place of a conventional solvent has led to an increase in unit operations, due to the additional step of preparing the solvent. This drawback is generally circumvented by eliminating the step of eliminating the NaDES, these solvents being recognized as biocompatible and safe [7,17,33,36].…”

“…In this context, Natural Deep Eutectic Solvents (NaDES) have been focusing the interest of researchers since the end of the 2010s. Numerous papers were published in various areas, such as analytical chemistry [2], biotechnology [3], energy [4], water treatment [5], food [6], cosmetic and pharmaceutics [7,8] or nanotechnology [9]. NaDES were first introduced by Choi et al in 2013 [10].…”

With the growing interest in more environmentally friendly solvents and processes, the introduction of Natural Deep Eutectic Solvents (NaDES) as low cost, non-toxic and biodegradable solvents represent a new opportunity for green and sustainable chemistry. Thanks to their remarkable advantages, NaDES are now arousing growing interest in many fields of research such as food, health, cosmetics and biofuels. Around the world, NaDES are seen as a promising alternative to commonly used petrochemical solvents. The objective of this review is to draw up a panorama of the existing skills on NaDES in French laboratories and industries for the valuation of natural products. This review therefore focuses on current applications, skills and perspectives, in order to analyze the place of French research in the use of NaDES for the valorization of biomass since 2015.
