Special Issue Information

Dear Colleagues,

Lactic acid bacteria (LAB) are a widespread bacterial group that has a prominent role in food fermentation. LAB produce organic acids and other metabolites that enhance flavour and aroma development in food and prevent spoilage, increasing product shelf-life. Therefore, they are very useful in many food applications. Together with their technological role, they possess metabolic properties that can improve the nutritional and functional quality of food.  Indeed, they can increase nutrient bioavailability, producing health-promoting compounds such as peptides with biological activities, gamma-aminobutyric acid and polysaccharides, and they can act as probiotics. The aim of this Special Issue is to discuss recent developments of the impact of microbial metabolism on the nutritional and functional quality of foods. Topics of interest will include advances in the exploitation of novel LAB strains for the development of fermented plant-based food or by-products with enhanced functional properties. Purely technological studies will be not considered. Due to their growing interest, special attention will be given to studies related to  the use of postbiotics.  For this Special Issue, we welcome original research articles and reviews of studies that address the scientific questions and research methodologies outlined above.

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. Fermentation is an international peer-reviewed open access monthly 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 2100 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.

Recent research has focused on yogurts supplemented with plant-derived and apiculture ingredients to enhance functional properties. This study evaluates the symbiotic potential of provitamin A carotenoids, dietary fiber, and oligosaccharides from carrots, mangoes, and honeydew honey in probiotic-enriched bioyogurt. Formulations were assessed during fermentation (45 °C ± 1 °C for 5 h) and refrigerated storage (4 °C ± 1 °C for 21 days). Probiotic and starter culture viability was determined using pour-plate counts on MRS agar. Physicochemical parameters including pH, titratable acidity, total soluble solids, water-holding capacity, and antioxidant metrics (total phenolics and carotenoids) were analyzed. After 21 days of storage, the probiotic culture (VEGE 092) reached 10.26 log CFU/mL and the starter culture (YOFLEX) achieved 8.66 log CFU/mL, maintaining therapeutic thresholds. Total carotenoid content increased significantly (p < 0.05) from 2.15 to 3.96 µg β-carotene/g, indicating synergistic interactions between lactic acid bacteria and plant-derived bioactive compounds. These findings demonstrate that combining plant-derived carotenoids, prebiotic fibers, and honeydew oligosaccharides effectively maintains probiotic viability and enhances antioxidant stability throughout fermentation and refrigerated storage, supporting the development of functional dairy products with improved nutritional profiles.
