“…Thus, one oxidation peak was expected from the oxidation of vanillin to form 1,2-benzoquinone that was subsequently reduced by the BDD electrode via + 2e À / + 2H + . This pathway of vanillin oxidation has also been suggested previously using a platinum (Pt) electrode in ACN with tetrabutylammonium hexafluorophosphate (TBAHFP) as the supporting electrolyte [34].…”

The electrooxidation mechanisms of guaiacol (2‐methoxyphenol), a food and beverage spoilage metabolite, and its precursors; vanillic acid (VA), vanillin, and ferulic acid (FA) were investigated by cyclic voltammetry (CV) with a boron‐doped diamond (BDD) electrode. Reversed‐phase liquid chromatography (RPLC) together with a BDD electrode poised at +1.6 V vs. Pd/H2, was optimized for their sensitive detection. The separation was achieved in 60 s with a core‐shell column (HALO C18). The detection limits of these analytes ranged from 10–30 nM. The method was applicable for the analysis of guaiacol and its precursors from a popular commercial drink.

“…CV has been applied for the determination of many antioxidants of food interest. Relevant examples include the study of caffeic acid [57], vanillin [58], tannins [59], piperine [60] and vitamins [61]. However, CV has been also used to characterize more complex samples, such as coffee extracts [62], wines [56,[63][64][65][66][67], beverages (teas, coffees, fruit juices) [56,68,69], sesame oil [70], algae [71,72], fruit juices [73], propolis [74,75], fruit infusions [76], seaweeds [77], mango fruit [78], dry herbal extract [79], kiwifruit [80], wild bilberry extract [81], berry fruits [82], apple flesh and peel [83], grape [84], medicinal plant and leave extract [85][86][87][88], ginger species [89,90], dried fruit extracts [91], bee products [92,93], amaranth flower and leave extract [94] and by-products (seed, stems, and pomace) [95].…”

Electrochemical Methods to Evaluate the Antioxidant Activity and Capacity of Foods: A Review

Antioxidants are an important class of food additives playing the fundamental role of retarding oxidation reactions in food. Although their functional role is well‐established, less clear is their mechanism of action. Electrochemical methods based on cyclic, differential pulse, square wave voltammetry and coulometry allow direct and rapid screening of antioxidant activity. Their main advantages are sensitivity, rapidity, simplicity and the capacity to directly measure the number of electrons transferred by an antioxidant offer advantage over conventional spectrophotometric assays. This review aims to summarize the most recent efforts towards the use of electrochemical methods to evaluate the antioxidant activity of foods.

Significant attention has been devoted to using biomass as a renewable resource to address the energy crisis and mitigate environmental pollution. Biomass, a potential substitute for fossil fuels, contains a substantial amount of lignin, ranging from 10 % to 25 %. Hence, it is crucial to research lignin depolymerization. In this study, the use of electrochemically catalyzed ionic liquids enabled the cracking of lignin at low temperatures. Specifically, by applying a low voltage at 230 °C, the controlled generation of vanillin and guaiacol was achieved. The concentration of vanillin in the depolymerized lignin reached 88.54 % under 3 V conditions. Similarly, it is presumed that the yield of guaiacol at 4 V is 48.24 %. These findings have significant implications for the targeted management of lignin depolymerization byproducts. Ultimately, this project establishes a framework for the high‐value utilization of biomass and provides new perspectives on addressing the energy problem and environmental degradation.
