“…To ensure the health of people, accurate and rapid determination of BHA and TBHQ is indispensable. Although conventional instrumental methods such as high-performance liquid chromatography (HPLC) [18], gas chromatography-mass spectrometry (GC-MS) [19] and UV-visible spectrophotometry [20] have been used for the detection of antioxidants, they are always highly technical, cumbersome and time-consuming. Electrochemical sensors 8 offer a timely alternative for BHA and TBHQ detection because of their simplicity, feasibility for miniaturization, rapid and sensitive quantitative analysis [21,22].…”

“…As a major source of lipids and micronutrients in the human diet, the QC of vegetable oils in the food industry is of great concern . Various analytical methods have been reported for determining SPAs in edible oils individually or simultaneously, including LC and HPLC , HPLC–MS , GC , GC–MS , voltammetry and MEKC . However, the reported methods usually suffer from large quantities of organic solvents in liquid solvent extraction or in the elution procedure of SPE, require a large amount of sample, and waste time.…”

A simple, rapid, organic-solvent- and sample-saving pretreatment technique, called dispersive liquid-liquid microextraction, was developed for the determination of six synthetic phenolic antioxidants from edible oils before high-performance liquid chromatography with diode array detection. The entire procedure was composed of a two-step microextraction and a centrifugal process and could be finished in about 5 min, only consuming only 25 mg of sample and 1 mL of the organic solvent for each extraction. The influences of several important parameters on the microextraction efficiency were thoroughly investigated. Recovery assays for oil samples were spiked at three concentration levels, 50, 100 and 200 mg/kg, and provided recoveries in the 86.3-102.5% range with a relative standard deviation below 3.5%. The intra-day and inter-day precisions for the analysis were less than 3.8%. The proposed method was successfully applied for the determination of synthetic phenolic antioxidants in different oil samples, and satisfactory results were obtained. Thus, the developed method represents a viable alternative for the quality control of synthetic phenolic antioxidant concentrations in edible oils.

“…However, the surfactants had low efficiency for the extraction of synthetic phenolic antioxidants from edibles and the toxic organic solvents sometimes was still required to improve the extraction efficiency. Specifically, Amlashi et al first reported a water-contained surfactant-based vortex-assisted microextraction method to extract and preconcentrate TBHQ and BHA in edible oils [34]. In the method, Brij-35 aqueous solution (the extraction) was injected into oil samples by micro-syringe, which was followed by a vortex agitator procedure instead of using organic disperser solvent to accelerate the forming of a cloudy solution and centrifugation procedure to achieve phase separation.…”

Synthetic antioxidants play a critical role in the storage and process of edible oils due to that they can retard lipid oxidation, maintain the quality of oils, and prolong the shelf life. However, a series of studies have proved the potential risks of synthetic antioxidants for human health when consumed in excess, and many countries have established the permitted amounts of synthetic antioxidants in oils. Thus, the accurate quantification of synthetic antioxidants in edible oils is necessary, and there have developed various analytical methods involved in chromatographical, electrochemical, and spectroscopic methods. Owing to the complex matrix and the incompatibility between the oil sample and the detection instrument, sample preparation is usually adopted prior to the instrument detection to improve the detection effectiveness. The current review aims to provide a comprehensive overview of the recently developed sample preparation methods and analytical techniques applied to determine synthetic antioxidants in edible oils from 2010 to present, with emphasis on the sample preparation methods combined with separation-based analytical techniques such as capillary electrophoresis and liquid chromatography with various detectors. The advantages and limitations of some typical analytical methods are discussed and some insights in the future perspectives are also provided in this review.
