Today, the increasing demand for minimally processed foods that are at the same moment nutritious, organoleptically satisfactory, and free from microbial hazards challenges the research and development to establish alternative methods to reduce the level of bacterial contamination. As one of the recent emerging nonthermal methods, pulsed light (PL) constitutes a technology for the fast, mild, and residue-free surface decontamination of food and food contact materials in the processing environment. Via high frequency, high intensity pulses of broad-spectrum light rich in the UV fraction, viable cells as well as spores are inactivated in a nonselective multi-target process that rapidly overwhelms cell functions and subsequently leads to cell death. This review provides specific information on the technology of pulsed light and its suitability for unpackaged and packaged meat and meat products as well as food contact materials like production surfaces, cutting tools, and packaging materials. The advantages, limitations, risks, and essential process criteria to work efficiently are illustrated and discussed with relation to implementation on industrial level and future aspects. Other issues addressed by this paper are the need to take care of the associated parameters such as alteration of the product and utilized packaging material to satisfy consumers and other stakeholders.
如今，人们对营养丰富、感官满意且无微生物危害的低加工食品的需求不断增加，这对研究和开发替代方法以降低细菌污染水平提出了挑战。作为最近出现的非热方法之一，脉冲光 (PL) 构成了一种用于在加工环境中快速、温和且无残留地对食品和食品接触材料进行表面消毒的技术。通过富含紫外线部分的高频、高强度广谱光脉冲，活细胞和孢子在非选择性多靶过程中失活，该过程迅速破坏细胞功能，随后导致细胞死亡。本文提供了关于脉冲光技术的具体信息，以及其在未包装和包装肉类及肉类产品以及生产表面、切割工具和包装材料等食品接触材料中的适用性。本文结合工业应用和未来方面，阐述并讨论了其优点、局限性、风险和必要的工艺标准，以实现高效操作。本文还涉及了需要注意相关参数的问题，例如产品和所用包装材料的变化，以满足消费者和其他利益相关者的需求。
