“…New types of green extraction solvents have also been introduced in the use such as ionic liquids (IL) [30,[58][59][60], and their future via the deep eutectic solvents (DESs) [36], supramolecular solvents (SUPRAs) [35], biosorption (bio)-based DLLME by the use the surfactants as dispersive solvents (surfactant-assisted [SA]-DLLME) [61] or as a extraction solvent (cloud-point [CP]-DLLME) [54], and switchable solvents (SS) [23,37,62] have led to the development of new LPME techniques.…”

“…In complex samples, it is more difficult to obtain a separated floating organic drop due to the interaction of the matrix components with the organic solvents [21]. Therefore, researchers in the field developed ad hoc methods to determine the target analytes in specific matrices, such as rice [22], meat [20,23], cheese [24], milk [25], wine [26], urine [27], honey [25], and plasma [1].…”

“…In addition, three LPME sampling modes could be recognized based on the number of immiscible phases concerned. These are two-, three-, [33,34] and four-phase [23,[35][36][37] LPME modes; for the latter mode, an auxiliary solvent is provided to adjust the density of the extraction phase. Table 1 shows the possible applications and tools that have already been used in previous scientific productions, which will be analyzed in the following paragraphs.…”

Sample pretreatment is the first and the most important step of an analytical procedure. In routine analysis, liquid–liquid microextraction (LLE) is the most widely used sample pre-treatment technique, whose goal is to isolate the target analytes, provide enrichment, with cleanup to lower the chemical noise, and enhance the signal. The use of extensive volumes of hazardous organic solvents and production of large amounts of waste make LLE procedures unsuitable for modern, highly automated laboratories, expensive, and environmentally unfriendly. In the past two decades, liquid-phase microextraction (LPME) was introduced to overcome these drawbacks. Thanks to the need of only a few microliters of extraction solvent, LPME techniques have been widely adopted by the scientific community. The aim of this review is to report on the state-of-the-art LPME techniques used in gas and liquid chromatography. Attention was paid to the classification of the LPME operating modes, to the historical contextualization of LPME applications, and to the advantages of microextraction in methods respecting the value of green analytical chemistry. Technical aspects such as description of methodology selected in method development for routine use, specific variants of LPME developed for complex matrices, derivatization, and enrichment techniques are also discussed.

“…Automation is capable of minimizing the operator risks, waste generation, energy and solvent consumption [59]. In this regard, many innovative ideas for automated DLLME including automated agitation-assisted demulsification DLLME [63], effervescence assisted DLLME [64] and DLLME-switchable polarity dispersive solvent (DLLME-SPDS) [65] have over the years been introduced. The former method used agitation for the phase separation and the whole automated process requires only a total of 160 µL of solvents.…”

Dispersive liquid-liquid microextraction (DLLME) is a novel sample preparation technique that has higher level of extraction efficiency by means of relying on microvolumes of solvents. It has gained considerable attention from researchers owing to several advantages such as its simplicity, shorter extraction time, lower cost and higher enrichment factor. In conventional DLLME, chlorinated solvents are widely used as the extraction solvents. Notwithstanding, most of these solvents are reportedly toxic and environmentally-unfriendly. Many related studies in recent years have focused on the use of nontoxic or low toxic extraction solvents and better practical procedures, which have helped improve the extraction efficiency. The aim of this review is to discuss the development of low toxic extraction solvent used recently in the DLLME. The possible improvement of extraction solvent from the green analytical chemistry perspectives is also discussed.Keywords: extraction solvents, dispersive liquid-liquid microextraction, green analytical chemistry Abstrak Pengekstrakan mikro cecair-cecair serakan (DLLME) merupakan teknik penyediaan sampel novel yang mempunyai lebih tinggi kecekapan pengekstrakan dengan menggunakan mikroliter pelarut. Teknik ini telah mendapat perhatian daripada penyelidik kerana beberapa kelebihan seperti ringkas, masa pengekstrakan yang lebih pendek, kos yang lebih rendah dan faktor pengayaan yang lebih tinggi. Dalam DLLME konvensional, pelarut berklorin digunakan secara meluas sebagai pelarut pengekstrakan. Namun, kebanyakan pelarut ini dilaporkan toksik dan tidak mesra alam. Dalam tahun kebelakangan ini, banyak kajian yang berkaitan telah fokus kepada penggunaan pelarut pengekstrakan yang tidak bertoksik atau rendah toksik dan praktikal prosedur yang lebih baik telah meningkatkan kecekapan pengekstrakan. Tujuan kajian ini adalah untuk membincangkan perkembangan pelarut pengekstrakan rendah toksik yang digunakan dalam DLLME terkini. Penambahbaikan pelarut pengekstrakan dari perspektif kimia analisis hijau juga dibincangkan.Kata kunci: pelarut pengekstrakan, pengekstrakan mikro cecair-cecair serakan, kimia analitik hijau

[15,16] The electronic tongue, which can simulate the human sense of taste, is a good tool for distinguishing the differences between samples.

In this study, the taste contribution of brown sugar in chicken seasoning was evaluated. Chicken seasonings containing brown sugar (AB), white sugar (AW), and liquid sugar (AL) were compared by the detection of taste compounds, sensory evaluation, and electronic tongue measurements. The correlation model of the three kinds of data was built by partial least squares regression (PLSR). The contents of the taste compounds in sample AB was higher than in sample AW and lower than in sample AL. Sample AB had the strongest "umami" and "full-body" taste and the highest response values for the UMS and GPS sensors. Combined with the PLSR results, brown sugar could be used to balance the taste of chicken seasoning. In conclusion, brown sugar had a positive effect on flavor quality and could help to improve chicken seasoning recipes. ARTICLE HISTORY
