Abstract

Food colorants are frequently added to processed foods since color is an important tool in the marketing of food products, influencing consumer perceptions, preferences, and purchasing behavior. While synthetic dyes currently dominate the food colorant market, consumer concern regarding their safety and sustainability is driving a demand for their replacement with naturally derived alternatives. However, natural colorants are costly compared to their synthetic counterparts as the pigment content in the native sources is usually very low and extraction can be challenging. Recent advances in the engineering of microbial metabolism have sparked interest in the development of cell factories capable of producing natural colorants from renewable resources. This review summarizes major developments within metabolic engineering for the production of nature-identical food colorants by fermentation. Additionally, it highlights common applications, formulations, and physicochemical characteristics of prevalent pigment classes. Lastly, it outlines a workflow for accelerating the optimization of cell factories for the production or derivatization of nature-identical food colorants.

利用微生物工程技术生产天然食用色素的最新进展
食品着色剂经常被添加到加工食品中,因为颜色是食品营销的重要工具,会影响消费者的认知、偏好和购买行为。虽然合成染料目前在食品着色剂市场上占主导地位,但消费者对其安全性和可持续性的担忧推动了用天然替代品取代合成染料的需求。然而,与合成色素相比,天然色素的成本较高,因为天然色素的色素含量通常很低,提取也很困难。微生物新陈代谢工程学的最新进展激发了人们对开发能够利用可再生资源生产天然着色剂的细胞工厂的兴趣。本综述总结了通过发酵生产天然色素的新陈代谢工程的主要进展。此外,它还重点介绍了常见色素的应用、配方和理化特性。最后,它还概述了加速优化细胞工厂的工作流程,以生产或衍生自然相同的食品着色剂。
