Abstract

Natural pigments are an indicator component in the freshness indicator, which is advantageous due to their safety, renewability, and low cost. However, freshness indicator with natural pigments as pH indicators has the problems of low stability and the color rendering domain could not effectively cover the shelf life of food. This paper describes the types and structures of natural pigments commonly used in freshness indicators and their color change mechanisms under different pH conditions. Also, the preparation methods of natural pigments freshness indicators are reviewed. Based on the current limitations and shortcomings faced by natural pigments freshness indicators, this paper highlights optimization strategies to enhance their sensitivity and stability, including modification, co-pigmentation, natural pigments mixing, encapsulation, and metal-ion complexation. The exploitation of these optimization strategies can help develop natural pigment-based intelligent packaging with superior performance to meet the food industry's needs for quality and safety monitoring.

提高 pH 值响应型保鲜指示剂中天然色素的灵敏度和稳定性：综述

天然色素是保鲜剂中的一种指示成分，具有安全、可再生、成本低等优点。然而，以天然色素作为 pH 值指示剂的保鲜指示剂存在稳定性低、显色域不能有效覆盖食品保质期等问题。本文介绍了保鲜指示剂中常用的天然色素的种类、结构及其在不同 pH 条件下的变色机理。此外，还综述了天然色素保鲜剂的制备方法。基于目前天然色素保鲜剂所面临的局限性和不足，本文重点介绍了提高其灵敏度和稳定性的优化策略，包括改性、共着色、天然色素混合、封装和金属离子络合等。利用这些优化策略有助于开发性能优越的基于天然色素的智能包装，以满足食品行业对质量和安全监控的需求。
