The hypothesis of this study is centered around the logic that an enhanced analysis of potential allergens during the food production can lead to increased accuracy and reliability of food labeling. The development of a cost-effective and straightforward optoelectrical microanalytical system for the simultaneous quantification of the six most common food allergens (peanut, hazelnut, almond, milk, wheat, and soybean) is presented. The system uses a regular versatile disc (DVD) functionalized with highly selective antibodies in a microarray format and a DVD drive as the optical detector. The multiplexed assay reliably (RSD < 20 %) determines the level of the allergenic proteins ranging from 0.1 to 143.4 ng mL. The analysis of food consumables (biscuits, seafood substitutes, and probiotic foods) revealed a 100 % accuracy in identifying the allergens ingredients declared on the label. The method offers potential for application as a high throughput biosensing tool for screening multiple allergens in commercial foods.
本研究的假设集中在这样一个逻辑上,即对食品生产过程中的潜在过敏原进行更深入的分析,可以提高食品标签的准确性和可靠性。本研究提出了一种经济高效且简单的光电微分析系统,用于同时定量分析六种最常见的食物过敏原(花生、榛子、杏仁、牛奶、小麦和大豆)。该系统使用常规的多功能光盘(DVD),以微阵列的形式进行高度选择性抗体功能化,并使用 DVD 驱动器作为光学探测器。该多重分析方法可靠地(RSD<20%)测定了过敏原蛋白的水平,范围从 0.1 到 143.4ng/mL。对食品消费品(饼干、海鲜替代品和益生菌食品)的分析表明,该方法在识别标签上声明的过敏原成分方面具有 100%的准确性。该方法有望作为一种高通量生物传感工具,用于筛选商业食品中的多种过敏原。
