基于天然色素的食品新鲜度指示包装研究进展

Research Progress of Food Freshness Indicator Packaging Based on Natural Pigment

随着食品安全意识的不断增强,消费者希望通过更加快捷直观的方式了解他们所购买食品的质量。由此出现了能在食品运输和储藏过程中,向人们提供食品质量信息的食品新鲜度指示包装。考虑到食品的安全性,越来越多的研究者开始利用植物中提取的天然色素作为指示剂。本文综述了近年来以花青素、姜黄素、茜素和紫草素为染料的食品新鲜度指示膜的研究现状。分析了基于天然色素的食品新鲜度指示膜在生鲜肉、水产品、牛奶和水果中的应用原理及其研究进展,并对食品新鲜度指示包装的研究和应用前景进行了展望。

As awareness of food safety grows,consumers want to know the quality of the food they buy in a quicker and more intuitive way.Food freshness indicator packaging,which offers information about the quality of food throughout transport and storage,has become more common as a result of this.Considering the safety of food,more and more researchers are using natural pigments derived from plants as indicators.This paper reviews the current status of research on food freshness indicator films using anthocyanins,curcumin,alizarin and shikonin as dyes in recent years.The principles of the application of natural pigment-based food freshness indicator films in raw meat,aquatic products,milk and fruits and the progress of their research are analysed,and the prospects of research and application of food freshness indicator packaging are also prospected.
