“…In 2012, the EFSA's panel of food additives concluded that the exposure to BHA as a food additive did not exceed the ADI of 1 mg/kg of body weight, even for the highest consuming population, but, this ADI was exceeded when the combined exposure as food additive and food contact material was taken into consideration. The target of BHA is controlling rancidification of animal fat in foodstuffs, given its low effectiveness on vegetable fat (Branen et al, 2001;EFSA, 2011;Roushani & Sarabaegi, 2014;Wang et al, 2015).…”

Background: Food antioxidants play a critical role in the food industry, and have become one of the most widespread methods of conserving food. Their cheapness and ease of use have made them a part of virtually all foodstuffs. Although different, all groups of food antioxidants have a same common objective, to conserve food for the longest possible time without altering it, conferring taste or color. Consumer trends have shifted the industry to find natural antioxidants for conservation, and although synthetic additives have been the mainstream, their natural counterparts have been gaining interest. Scope and approach: This review focuses of the different antioxidant groups, describing their properties, function and applicability, as well as indexing the relevant legislation in order to be a guide for academia and industry. Key findings and conclusions: The wide number of antioxidant additives allowed by the different countries if of synthetic origin, and consist of pure molecules. Although consumers are leaning toward natural additives, this offer is still quite limited despite the permission of rosemary extract within the European Union. There is still much work to be done in order to completely demystify the importance and safety of antioxidants as well as to harmonize legislation worldwide.

“…The results displayed a linear detection range from 0.1 to 1.0 μM with a detection limit of 0.0949 μM. Roushani and co-workers demonstrated an iridium oxide nanoparticle-modified GCE for BHA determination [16]. The results indicated the proposed method had a linear range from 1~280 μM with a detection limit of 0.6 μM.…”

“…Electrochemical methods have been applied for the determination of BHA due to their simplicity, sensitivity, stability, rapid response, and low cost [14][15][16][17][18][19][20][21][22][23][24][25][26]. For instance, the electrochemical oxidation of BHA at a glassy carbon electrode (GCE) that was modified with AuNPs-PVP-graphene was investigated [14].…”

Here, we report a graphene oxide-wrapped coreshell structured carbon sphere@Al 2 O 3 composite (CS@Al 2 O 3 @GO) as the electrode material for sensitive determination of butylated hydroxyanisole (BHA). The coreshell structured CS@Al 2 O 3 was synthesized through a solution-based approach by using glucose and metal salts as precursors via a simple one-pot hydrothermal synthesis. Then, the CS@Al 2 O 3 was amino-functionalized and wrapped by conductive graphene oxide (GO) sheets through the electrostatic interaction. As a result, the CS@Al 2 O 3 @GO endowed the modified electrode fast electron transfer rate and high electrocatalytic activity toward BHA oxidation. Under the optimal conditions, the oxidation current increased linearly with the concentration of BHA in the range of 0.2~200 μM with the detection limit and quantification limit of 41 and 136.7 nM using differential pulse voltammetry. The presented method was also demonstrated for the determination of BHA in food samples with satisfactory results.

“…31 Because of the high electron transfer rate constant of Ir(IV)/Ir(III) redox couple, IrO x were used as an electron transfer mediator and successfully applied in electrocatalysis. [52][53][54][55] The present research reports an amperometric sensor for nitrite and AA detection, based on modified with iridium oxide GC electrode. As an electrode material, GC is distinguished by its chemical inertness, low background currents, wide potential window and low price.…”

Iridium oxide (IrO x) was electrodeposited onto glassy carbon electrode applying two-step potential cycling procedure. The electrocatalytic properties of the modified electrode IrO x /GC were evaluated with regards to electrochemical oxidation of nitrite and ascorbic acid (AA). The developed electrode-catalyst have been extensively studied by various electrochemical techniques. Differential pulse voltammetry (DPV) experiments indicated that the modified electrode possesses excellent electrocatalytic activity towards the oxidation of both nitrite and AA in neutral medium and offers simultaneous quantification of these substances. Constant potential amperometry studies also were performed-the IrO x / GC showed sensitive response to nitrite (159.7 μA mM-1 cm-2) with a wide linear range from 0.002 to 10 mM at 0.77 V (vs. Ag/AgCl, 3 M KCl), and to AA (96.2 µA mM-1 cm-2) with a linear range from 0.01 to 3 mM at 0.025 V. The detection limit was 0.63 μM nitrite and 4 μM AA, respectively, and both of them had fast response within 5 s. Considering the simple and rapid electrodeposition procedure for preparation, IrO x /GC is a new electrode-catalyst for sensitive and selective quantitative detection of nitrite and AA. The wide linear range, good selectivity, reproducibility of the amperometric response and long-time stability of the IrO x /GC make it a promising sensing material for practical nonenzymatic quantitative detection of nitrite and AA.
