泄漏指示剂在气调包装中的应用研究

Research on Leakage Indicators Applied in MAP

概述了气调包装及泄露指示剂的原理,综述了电化学、光学、比色法、压力激活氧气指示剂/传感器和光学、电化学二氧化碳指示剂/传感器在气调包装中的发展及应用,指出各指示剂在应用过程中可能存在的问题:指示剂中的有机或无机化合物可能会转移到食物中而造成食物污染,指示剂在检测过程中一定程度上会受到周围环境的影响而造成判断失误,指示剂生产成本较高等。未来指示剂的研发将更多地利用天然、安全的材料,以水性油墨的形式打印到标签上,建立一个有效的毒理学评价体系及动力学模型,并降低成本;同时,可将指示剂与其他智能包装技术相结合,实现同时监控包装内外环境的功能,还可将指示剂标签和互联网技术相结合,将产品的实时属性通过网络进行传输,实现产品质量的实时监控。

The modified atmosphere packaging（MAP） was summarized with the revelation of the principle and application of indicators by reviewing the electrochemical, optical, colorimetric method, pressure activated oxygen indicators/sensors and the development and application of optical and electrochemical CO2 indicator/sensor in modified atmosphere packaging（MAP）. The potential problems of each indicator in the application process were pointed out as： the possible transfer of organic or inorganic compounds of indicators to the food resulting in food pollution, indicators in the testing process to be affected by the environment and causing misjudgment to a certain extent, and the production cost being high,etc. Indicators of natural, safe materials will be vastly used in future research and development such as label printing in the form of water-based ink with the establishment of an effective system of toxicology evaluation and dynamic model to reduce costs. Meanwhile, the indicators could be combined with other intelligent packaging technology to achieve the function of monitoring the environment inside and outside the packaging. Moreover, the indicator label could also be combined with internet technology to transmit the real-time property of the product through the network to realize the real-time monitoring of product quality.
