摘要

膳食补充剂可以有针对性地提供人体所需营养。为深入挖掘和分析膳食补充剂领域的专利信息,观察技术动态、市场趋势及潜在创新方向,该文采用了潜在狄利克雷分布模型(latent Dirichlet allocation,LDA)对专利文献进行了主题建模分析。研究从HimmPat专利数据库中检索了截止于2024年的7 873份专利文件,并利用LDA模型对其摘要进行主题建模,结果表明膳食补充剂的核心技术聚焦于膳食补充剂的“药物疗效”“原料”“营养素”与“微生物”4个主题。随着科学研究的进步和消费者需求的不断变化,膳食补充剂的功能已经向更加个性化和多功能化的方向发展,利用先进技术从天然食材中提取生物活性化合物成为重要趋势。

Abstract

Dietary supplements can provide the nutrients the human body needs in a targeted manner.To deeply explore and analyze the patent information in nutritional supplements, observe technological dynamics, market trends, and potential innovation directions, this paper employs latent Dirichlet allocation (LDA) to conduct topic modeling analysis on patent literature.The study retrieved 7 873 patent documents from the HimmPat patent database up to 2024 and applied LDA to model the abstracts of these patents.The results indicate that the core technologies of dietary supplements focus on four themes:therapeutic efficacy,ingredients,nutrients, and microorganisms. With the advancement of scientific research and the changing consumer demands, the functions of dietary supplements have evolved towards more personalized and multifunctional directions.Using advanced technologies to extract bioactive compounds from natural foods has become a significant trend.
