Special Issue Information

Dear Colleagues,

Food quality control is always a hot topic in the food industry, especially regarding fermented foods. During food fermentation, microbial communities vary with regular processes, accompanied by converting substrates, such as carbohydrates, proteins, and lipids, into raw materials and beneficial metabolites (organic acids, alcohols, amino acids, peptides, fatty acids, etc.). These beneficial metabolites have a main nutritional composition and sensory and functional properties. Microbial diversity and metabolic regulation in fermented foods have undeniably become the main factors controlling food quality.

Therefore, this Special Issue aims to present recent advances in microbial diversity and the metabolic regulation of fermented foods. We encourage the submission of manuscripts that include, but are not limited to:

  • The succession of microbial communities during food fermentation;
  • Dynamic changes in organoleptic, nutritional, and functional characteristics during food processing;
  • The relationship between microbes and the metabolic activities of fermented products;
  • The effects of microbes on food safety and quality;
  • Main metabolisms and their regulation during food fermentation;
  • The industrial transformation of traditional fermented food;
  • Screening and applying functional microbes;
  • The correlation between microbes, the environment, and gut health;
  • The development of characteristic functional metabolites in fermented foods.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Marselan wine is characterized by distinctive flavors of blackcurrant, cranberry, and spice, which are significantly influenced by environmental factors such as region and climate. In this study, we analyzed the dynamic changes in the microbial community, physicochemical indices, and flavor compounds during the spontaneous fermentation of Marselan wine in Xinjiang using high-throughput sequencing (HTS), high-performance liquid chromatography (HPLC), and headspace solid-phase microextraction gas chromatography–mass spectrometry (HS-SPME-GC-MS). The results indicated that the sugar content decreased from 259.12 g/L to 22.45 g/L, while the ethanol content increased to 13.63 ± 0.15% vol after 12 days of fermentation. The predominant aromatic components identified in Marselan grapes include isophorone, 2,3-pentanedione, 2-hexenal, and melonal. After fermentation, ethanol, phenethyl alcohol, isoamyl acetate, ethyl acetate, and ethyl hexanoate were produced, imparting rose, cream, and fruit flavors to wine. The key microorganisms involved in the spontaneous fermentation of Marselan wine include Saccharomyces, Starmerella, Pichia, Pseudomonas, Sphingomonas, and Aspergillus. These microorganisms contributed substantially to the main physicochemical indices and flavor profiles. Saccharomyces and Pichia enhanced the formation of most alcohols and esters, whereas Aspergillus, Acremonium, and Fusarium inhibited the synthesis of numerous volatile compounds. These findings provide valuable theoretical references for improving the quality of Marselan wines in Xinjiang. Full article
