“…Firstly, the selection of antibody source used for development of sandwich immunosensor is very important [ [19] , [20] , [21] , [22] ]. In order to perform more sensitive analysis and also to prevent cross-reactions, immunosensors based on four different configurations (procedure A, B, C and D) were designed and prepared in our study.…”

“…When the biological receptor is a specific antibody and the analyte is an allergen recognized by that antibody, then the biosensor can be used to detect an allergen in a sample [ 58 ]. For instance, biosensors have been used to detect several individual allergens in food samples with high specificity and sensitivity, such as porcine albumin [ 59 ], peanut Ara h 1 [ 60 ] and Ara h 6 in commercially processed foods [ 61 ], Sin a 1 in mustard seeds [ 62 ], β-lactoglobulin in dairy products [ 63 ] and hazelnut Cor a 14 [ 64 ]. Biosensors are sensitive, specific, easy to use, fast and can be used multiple times.…”

Several factors can affect the allergen content and profile of a specific food, including processing procedures often leading to a decrease in allergenicity, although no change, or even an increase, have also been reported. Evaluation of the effectiveness of a processing procedure requires the availability of reliable methodologies to assess the variation in molecules able to induce allergic reactions in the analyzed food. Conventional and innovative strategies and methodologies can be exploited to identify allergenic proteins in foodstuffs. However, depending on the specific purposes, different methods can be used. In this review, we have critically reviewed the advantages of an innovative method, the multiplex allergen microarray-based immunoassay, in the detection of allergens in foodstuffs. In particular, we have analyzed some studies reporting the exploitation of an IgE-binding inhibition assay on multiplex allergen biochips, which has not yet been reviewed in the available literature. Unlike the others, this methodology enables the identification of many allergenic proteins, some of which are still unknown, which are recognized by IgE from allergic patients, with a single test. The examined literature suggests that the inhibition test associated with the multiplex allergen immunoassay is a promising methodology exploitable for the detection of IgE-binding proteins in food samples.

“…It is heat resistant and slightly affected by food processing exactly as Cor a 14. The first electrochemical immunosensors for Sin a 1 detection have been developed by the Pingarron group [ 104 ]. It involved a sandwich immunoassay where a capture antibody and a detector antibody, labeled as usual with HRP were included.…”

Food allergy has been indicated as the most frequent adverse reaction to food ingredients over the past few years. Since the only way to avoid the occurrence of allergic phenomena is to eliminate allergenic foods, it is essential to have complete and accurate information on the components of foodstuff. In this framework, it is mandatory and crucial to provide fast, cost-effective, affordable, and reliable analysis methods for the screening of specific allergen content in food products. This review reports the research advancements concerning food allergen detection, involving electrochemical biosensors. It focuses on the sensing strategies evidencing different types of recognition elements such as antibodies, nucleic acids, and cells, among others, the nanomaterial role, the several electrochemical techniques involved and last, but not least, the ad hoc electrodic surface modification approaches. Moreover, a selection of the most recent electrochemical sensors for allergen detection are reported and critically analyzed in terms of the sensors’ analytical performances. Finally, advantages, limitations, and potentialities for practical applications of electrochemical biosensors for allergens are discussed.
