Abstract

Daqu, a crucial fermentation starter in the production of various Chinese fermented foods, plays a pivotal role in shaping complex enzyme profiles and diverse flavour precursors. This review aims to elucidate the microbial communities within Daqu, focusing on their functionalities in the context of flavour development. We delve into the detection methods of microorganisms and flavour substances in Daqu, employing advanced technologies including high-performance liquid chromatography, gas chromatography, pseudo-targeted metabolomics, and headspace solid-phase microextraction-gas chromatography-mass spectrometry. This review explores high throughput sequencing technologies, including pyrosequencing, clonal library sequencing, metaproteomic, and metagenomics, to gain a comprehensive understanding of the intricate microbial dynamics. Additionally, we discuss the metabolic pathways involved in flavour substance production within Daqu. By synthesizing information on Daqu types, microorganisms present, detection methodologies, and flavour substance metabolic pathways, this review contributes to a deeper comprehension of the intricate processes underpinning the Flavors of Chinese fermented foods.

期刊介绍： Process Biochemistry is an application-orientated research journal devoted to reporting advances with originality and novelty, in the science and technology of the processes involving bioactive molecules and living organisms. These processes concern the production of useful metabolites or materials, or the removal of toxic compounds using tools and methods of current biology and engineering. Its main areas of interest include novel bioprocesses and enabling technologies (such as nanobiotechnology, tissue engineering, directed evolution, metabolic engineering, systems biology, and synthetic biology) applicable in food (nutraceutical), healthcare (medical, pharmaceutical, cosmetic), energy (biofuels), environmental, and biorefinery industries and their underlying biological and engineering principles.
