传统酸面团中微生物种类及其对发酵馒头风味特性影响的研究进展

    Research Progress on Microbial Species in Traditional Sourdough and Flavor Characteristics of Chinese Steamed Bread

    • 摘要: 传统酸面团作为一种天然发酵剂,其微生物群落与产品风味特性是决定发酵面制品品质的核心要素。酸面团中的关键微生物主要包括乳酸菌和酵母菌,这些微生物通过代谢产生醇类、醛类、酯类、酮类、酸类和酚类等风味物质,从而决定了酸面团及其发酵馒头的主要风味特性。综述了传统酸面团中的主要微生物(乳酸菌、酵母菌)、酸面团发酵馒头中的风味物质,以及微生物与风味物质之间的关系,并对未来研究方向进行了展望,旨在为研究风味物质的种类及生成途径提供参考,为精准改善酸面团馒头风味奠定基础。

       

      Abstract: Traditional sourdough, as a natural starter culture, features microbial communitie s and flavor profiles that are pivotal determinants of quality in fermented cereal-based pro ducts. Lactic acid bacteria and yeasts represent the primary microorganisms in sourdough, capable of producing a wide array of flavor metabolites such as alcohols, aldehydes, ester s, ketones, organic acids, and phenolic derivatives. The microbial composition of sourdoug h significantly influences the flavor characteristics of both sourdough and Chinese steamed bread. This review examines the predominant microorganisms (lactic acid bacteria and yeas ts), flavor compounds, and their interconnections with the flavor profile of Chinese steame d bread. Furthermore, future research directions are proposed. The objective is to offer a r eference for investigating flavor compounds and their biosynthetic pathways, while establis hing a foundation for the precise regulation of Chinese steamed bread flavor.
