Abstract

In this work, three different dyes have been tested for the determination of gaseous ammonia. This gas is one of the products of microbial degradation and therefore its presence is an indicator of deterioration and could be used as a food freshness indicator. Three different sensors have been prepared and tested, two of them using the natural pigments curcumin and anthocyanin and the other one using bromothymol blue. All of them are biocompatible and therefore allowed to use in contact with food. Different compositions, materials for deposition, stability and reversibility for ammonia gas detection have been studied under high humidity conditions simulating real packaged food conditions. Colorimetry is the technique used to obtain the analytical parameter, the H coordinate of the HSV colour space, simply using a camera, avoiding the use of complex instrumentation. Sensibility, toxicity grade and stability found show that the sensor could be implemented in packaged food and form the basis of a freshness indicator for the food industry.

用于氨气检测的生物兼容传感器。

在这项工作中，对三种不同的染料进行了测试，以测定气态氨。这种气体是微生物降解的产物之一，因此它的存在是食品变质的一个指标，可用作食品新鲜度的指示剂。已经制备并测试了三种不同的传感器，其中两种使用天然色素姜黄素和花青素，另一种使用溴百里酚蓝。所有这些传感器都具有生物兼容性，因此可以与食品接触使用。在模拟真实包装食品的高湿度条件下，对氨气检测的不同成分、沉积材料、稳定性和可逆性进行了研究。比色法是一种用于获得分析参数（HSV 色彩空间的 H 坐标）的技术，只需使用照相机，避免使用复杂的仪器。所发现的灵敏度、毒性等级和稳定性表明，该传感器可用于包装食品，并为食品工业的新鲜度指示器奠定基础。

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
