Special Issue Information

Dear Colleagues,

The physicochemical properties of dairy products fundamentally govern their macro-functional performance, determining key attributes such as texture, stability, and nutritional efficacy. Understanding the "composition–structure–property–function" relationship is essential for advancing dairy science and meeting evolving consumer demands. This Special Issue aims to systematically compile the latest research advances and cutting-edge findings in this field, with a focus on the molecular structures of key dairy components, their interactions, and their dynamic evolution during thermal processing and storage. Specific research emphases include, but are not limited to, the following: the conformational transitions, aggregation kinetics, and interfacial behavior of dairy proteins and their impact on gel texture and stability; the crystallization behavior, emulsification mechanisms, and demulsification processes of milk fat globules and their correlation with product spreadability and mouthfeel richness; as well as the rheological properties, textural characteristics, and release-retention patterns of flavor compounds in dairy systems. By integrating multidisciplinary approaches, this collection elucidates critical structure–function relationships, supporting the development of next-generation, high-value dairy products with tailored functionalities and enhanced quality.

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 250 words) can be sent to the Editorial Office for assessment.

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.

This study evaluated the fermentation kinetics and properties of kefir beverages produced from whole milk using milk kefir grains (MKGs) or water kefir grains (WKGs) over 48 h. MKGs showed higher initial microbial loads and promoted rapid acidification, with pH decreasing from 6.70 to 4.99 and significant production of lactic acid (10.58 g/L) and ethanol (5.17 g/L), compared with WKGs (final pH 6.20, <0.5 g/L lactic acid, and <0.3 g/L ethanol). However, the final concentration of acetic acid in WKG fermentation (1.93 g/L) was comparable to that in MKG fermentation (2.02 g/L). Microbial populations increased in both systems, exceeding 106 CFU/mL—one of the requirements for conferring probiotic relevance to a beverage—with MKGs reaching higher counts. Lactose and protein consumption were greater in MKGs, suggesting more intense metabolic activity. Fermentation enhanced nutritional value by increasing vitamins B2, B3, B5, and pyridoxine, while vitamin D3 decreased. Mineral composition remained largely unchanged. Volatile analysis identified 31 compounds: MKGs favored fatty acids and lactones associated with creamy notes, whereas WKGs promoted ester formation and fruity aromas. Overall, both grain types produced microbiologically safe beverages with distinct biochemical and sensory profiles, demonstrating the feasibility of using WKGs for milk fermentation. Full article
