新鲜度指示型智能包装的研究进展

食品新鲜度指示型智能包装是利用食品在贮藏过程中释放的某些特征气体与特定试剂产生的特征颜色反应、温度激活生物学反应及酶作用等引起指示剂发生明显的变化,从而帮助消费者直观、准确以及科学的判断食品品质与新鲜程度。因此,食品新鲜度指示剂在实际生活中具有重要的应用价值。本文在归纳和分析国内外新鲜度指示型智能包装的基础上,分别从食品新鲜度指示剂应用类型与新鲜度指示剂基材两个方面阐述了新鲜度指示剂的指示原理与研究现状以及指示剂基材的制作工艺与材料选择,对现有研究成果进行总结,指出了研究中依然存在的问题并对未来的研究方向进行展望以及提出合理性研究建议,旨在为今后更深入的食品新鲜度指示剂技术研究提供借鉴和参考。

Review: Freshness Indicator Intelligent Packaging

Food freshness indicator intelligent packaging is developed based on characteristic color reactions, temperature-activated biological reactions and enzyme activations caused by characteristic gas and specific reagents released during the storage process of food products, and thus can be used to help consumers intuitively, accurately and scientifically judging the quality and freshness of foods. Food freshness indicators had important application values in real life. In this paper, based on the induction and analysis of the domestic and foreign freshness indicator intelligent packaging, the instruction principle research status and indications of the freshness indicator were explained from two aspects: the food freshness indicator application type and the freshness indicator substrate. The production process and material selection of the agent substrate, summarized the existing research results, pointed out the problems that still existed in the research and the direction of future research prospects and put forward reasonable research suggestions, aiming to study food freshness indicator technology more deeply and provide the reference.
