摘要： 茶多糖是茶葉中的重要活性成分,研究茶多糖的性質、推動茶多糖產品的開發(fā)將有利于茶產業(yè)及健康產業(yè)的發(fā)展。對Web of Science數據庫中近十年茶多糖相關文獻進行了可視化分析。結果顯示,2013—2022年,茶多糖相關主題發(fā)文量總體呈增長趨勢;關鍵詞的共現、突現、頻次分析結果均表明茶多糖的抗氧化性是持續(xù)的研究熱點,這也可能是未來研究的主要趨勢之一。當前,全球范圍內茶多糖的研究主要集中在單糖組成、溶解性、乳化性等理化性質和抗氧化、抗腫瘤、抗糖尿病等生物活性方面。茶多糖雖具有多種生物活性,但相關的機理解析仍不夠深入;最新研究表明茶多糖能夠影響腸道菌群,具有良好的益生元潛力。另外,茶多糖相關產品的轉化和開發(fā)尤為不足,研究者們未來可聚焦于利用茶多糖開發(fā)生物膜制品、藥物遞送產品及功能性食品等?？偨Y茶多糖領域研究的主要內容和熱點方向,旨在為該領域的研究者及茶多糖產業(yè)的發(fā)展提供參考。

Abstract: Tea polysaccharides are important active ingredients in tea. Studying the properties of tea polysaccharides and promoting the development of tea polysaccharides products will benefit both the tea industry and the health industry. In the present paper, literatures related to tea polysaccharides from the Web of Science database over the past decade were visually analyzed. The results show that the overall number of papers related to tea polysaccharides showed an increasing trend from 2013 to 2022. The co-occurrence, emergence and frequency analysis of keywords show that the antioxidant activities of tea polysaccharides are a continuous research hotspot, which may also be one of the main trends in future research. At present, global research on tea polysaccharides mainly focuses on the physicochemical properties including monosaccharide composition, solubility, emulsification and biological activities such as antioxidation, anticancer and antidiabetic. Although tea polysaccharides exhibit a variety of biological activities, the underlying mechanisms are still not well understood. Recent studies have shown that tea polysaccharides can exert probiotic potential by affecting gut microbiota. In addition, the transformation and development of tea polysaccharide-related products are particularly insufficient. In the future, researchers can focus on developing biofilm products, drug delivery vehicles and functional foods using tea polysaccharides. Overall, the present paper summarized the main contents and hot spots in the field of tea polysaccharides, aiming to serve as a reference for researchers in this field as well as for the development of the tea polysaccharide industry.

Key words: tea polysaccharides, visual analysis, antioxidation, gut microbiota
