“…However, microwaveassisted digestion (MWAD) is considered the state of the art in sample preparation as it reduces solvent consumption and is faster than acid digestion, combining high temperature and high pressure [22]. Notwithstanding, due to its low cost and for the unique conditions provided by acoustic cavitation, ultrasound-assisted extraction (UAE) has evolved in the last decades as an efficient alternative to MWAD, enhancing solid sample pretreatment, promoting green aspects such as energy requirements, and minimizing solvent consumption [23][24][25][26].…”

Sorghum is the fourth most important cereal produced in Argentina and the fifth worldwide. It has good agronomic characteristics and could be developed in arid areas, allowing a wide geographic distribution. Its starch content, higher than 70%, makes it possible to obtain a good yield of flours. Nutritionally, it should be noted that the grain does not have the protein fraction called prolamins, which makes it suitable for consumption by people with celiac disease. The multielemental composition constitutes an important indicator of the nutritional profile of the grains and allows, together with other parameters, to select the most suitable varieties for human consumption. In its determination, the preanalytical stage is decisive to obtain a reliable result. Organic samples are a challenge for sample introduction systems that use plasma-based techniques. As an alternative to conventional pretreatment with a microwave-assisted digestion (MWAD), a greener, quick, and simple treatment is proposed, using ultrasound-assisted extraction (UAE) in diluted acid media. The UAE method accelerates analysis times, improves performance and productivity, and was applied to sorghum samples cultivated in the province of La Pampa (Argentina). Microwave-induced plasma optical emission spectrometry (MIP OES) was employed for the determination of Cu, K, Mg, Mn, P, and Zn. The detection limits found ranged from 0.6 (Cu) to 89 (P) mg kg−1, and the precision expressed by the relative standard deviation (RSD) was ≤7.7% (Zn). For validation, a maize reference material (NCS ZC 73010) was evaluated. The principal component analysis revealed three different groupings related to the sorghum varieties’ mineral profile.

“…Pascariu and coworkers [164] recorded no heavy metal pollution as they analyzed waters from a pristine source to evaluate if MP-AES was sensitive enough to assess low-level contaminants in creek water (from Piule-Iorgovanul Mountains) and if such water was apt for human consumption according to 98/83/EC. Zaldarraiga Heredia [166] compared traditional microwave-assisted digestion with an ultrasound-assisted one to assess multiple elements in Argentine corn, though MP-AES using In as an internal standard. Rajmund and coworkers [167] analyzed n = 31 herbal tea samples, an application relevant since fertilization and environmental pollution will influence these plant materials.…”

This review presents an overall glance at selected instrumental analytical techniques and methods used in food analysis, focusing on their primary food science research applications. The methods described represent approaches that have already been developed or are currently being implemented in our laboratories. Some techniques are widespread and well known and hence we will focus only in very specific examples, whilst the relatively less common techniques applied in food science are covered in a wider fashion. We made a particular emphasis on the works published on this topic in the last five years. When appropriate, we referred the reader to specialized reports highlighting each technique’s principle and focused on said technologies’ applications in the food analysis field. Each example forwarded will consider the advantages and limitations of the application. Certain study cases will typify that several of the techniques mentioned are used simultaneously to resolve an issue, support novel data, or gather further information from the food sample.

“…To investigate the physiological activity of the plant, the concentrations of Cr, Mn, Mo, Zn, Fe, Co, Cu, Al, Ni should be determined (Filipiak-Szok et al, 2015;Heredia et al, 1016). When the plant included excessive or low amount of these metals, it caused to a negative effect for the plant health (Heredia et al, 2016). Because some metals such as Pb, Ni, and Co hinder to ecesis as well as make prohibition effects on the plants (Mohamed et al, 2017), determination of metals in the plants were important.…”

Genus Lathyrus L. belonging to Fabaceae (Leguminosae) family consisted of 77 taxa at the species, subspecies, and variety level at Turkey and 25 of that were known as endemic. Lathyrus egirdiricus H.Genc & A.Sahin and Lathyrus tefennicus H. Genç & A. Şahin were endemic species and described at the date of 2008 and 2011, respectively. The seeds of Lathyrus tefennicus and Lathyrus egirdiricus were collected in Tefenni of Burdur province and Eğirdir of Isparta province in May of 2016 at Turkey. The concentration of Cd, Cr, Ni, Cu, Mn, Zn, Fe, Ca, Mg, Na and K in the Lathyrus tefennicus and Lathyrus egirdiricus seeds were determined by Atomic Absorption Spectrometry. A microwave oven was used for the sample digestion. The accuracy of proposed method was confirmed by the analysis of the certified reference material (EnviroMAT Contaminated Soil). All results were given at 95% of confidence level. The presence of different concentrations of elements in the seeds of both species strengthens the belief that this data can be used in plant taxonomy.
