Pulsed Light (PL) is now recognized as a promising non-thermal food processing technology with a wide range of applications in disinfection, extending shelf life, and inhibiting allergic reactions from the consumption of certain foods. In recent years, the research in PL has developed rapidly, and the knowledge domain associated with this area has made significant progress. Interested scholars in this and allied areas need to keep up with the new tendency and critical developments. In this study, a progressively integrated network is derived from 475 archived articles on PL technology obtained from the Web of Science Core Collection (WoSCC) database in “Food Science Technology” between 2011 and 2020. These scientific documents were analyzed through HistCite and CiteSpace. The hot-spots and landmark references of PL technology were obtained by scientometric analysis. This review will guide scholars to track new trends and identify critical new applications of PL technology in the food industry.

脉冲光 (PL) 现在被认为是一种很有前途的非热食品加工技术，在消毒、延长保质期和抑制因食用某些食物引起的过敏反应方面具有广泛的应用。近年来，PL的研究发展迅速，与该领域相关的知识领域取得了重大进展。对此和相关领域感兴趣的学者需要跟上新趋势和批判性发展。在这项研究中，从 2011 年至 2020 年间从“食品科学技术”中的 Web of Science 核心合集 (WoSCC) 数据库中获得的 475 篇关于 PL 技术的归档文章衍生出一个逐步整合的网络。这些科学文献通过 HistCite 和 CiteSpace 进行了分析。通过科学计量分析获得PL技术的热点和标志性参考。这篇综述将指导学者跟踪新趋势并确定 PL 技术在食品行业中的关键新应用。
