Special Issue Information

Dear Colleagues,

Fermented foods have a long history and rich variety, and they are popular all over the world. The fermentation of beneficial microorganisms can not only preserve foods effectively, but also give the foods a unique flavor and enrich their nutritional value. The precise development and utilization of superior strains in traditional fermented foods is of great significance for the improvement of their quality. A comprehensive analysis of the functional properties of beneficial microorganisms in fermented foods is a theoretical prerequisite for the development of high-quality fermented foods. In this process, we need to analyze the formation mechanism of unique flavor in fermented foods, the formation and/or enrichment mechanism of nutritional functions, and the mechanism of microorganisms in the preservation of fermented foods. In addition, dissecting the process points of traditional fermented foods, realizing their scale and industrial production, or creating innovative fermented foods are also urgent technical barriers that need to be solved in the current fermented food industry. We are pleased to invite you to submit papers to this Special Issue that highlight the functional properties of microorganisms in fermented foods and the innovative applications of food microorganisms and their metabolism in fermented foods.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

(1) The mining and transformation of dominant strains and their fermentation characteristics;

(2) The evaluation of the functional properties of fermented foods;

(3) Applications of beneficial microorganisms and their metabolites in food;

(4) Process control technology of fermented foods;

(5) The mechanism of the formation of flavor and functional nutrition in fermented foods and evaluation methods;

(6) Novel fermented foods.

We look forward to receiving your contributions.

Abstract
A functional set dahi (fermented milk analogous to yoghurt) with a desirable probiotic (Lactiplantibacillus plantarum A5) count of 9.36 log CFU/mL and excellent techno-functional attributes (DPPH: 41.95% RSA, firmness: 485.49 g, sensory overall acceptability: 8.51) was developed to contain 260 mg of [...] Read more.
A functional set dahi (fermented milk analogous to yoghurt) with a desirable probiotic (Lactiplantibacillus plantarum A5) count of 9.36 log CFU/mL and excellent techno-functional attributes (DPPH: 41.95% RSA, firmness: 485.49 g, sensory overall acceptability: 8.51) was developed to contain 260 mg of SDG in 20 g of dahi. Twenty-four female Albino Wistar rats (3 months old, >180 g) were ovariectomized (OVX) and divided into three groups: OVX control, OVX and control dahi, and OVX and SDG-enriched dahi. The animal study found that ovariectomy decreased serum calcium, oestrogen, and bone ash calcium levels by 32.27, 30.95, and 48.46 percent, respectively, compared to the sham group (n = 8), while daily administration of SDG-enriched dahi (20 g) for eight weeks restored them. The proximal tibial metaphysis and distal femoral epiphysis micro-CT study showed that the ovariectomy lowered bone mineral density (BMD) by 11.06% and 9.18%, respectively, and lowered Trabecular thickness (Tb. Th) by 12.66% and 11.86%, respectively, while increasing Trabecular separation (Tb. Sp.) by 90.69% and 87.70%, respectively, compared to the sham control-group rats. SDG-enriched dahi improved BMD by 16.06 and 12.24% and Tb. Th by 35.32 and 19.62%, respectively, and decreased Tb. Sp by 47.04 and 47.22%, respectively, in OVX rats. The results suggest that the developed set dahi may help treat postmenopausal osteoporosis. Full article

Abstract
Lactic acid bacteria have become popular because of their γ-aminobutyric acid (GABA)-producing ability. In the present study, we selected four Levilactobacillus brevis strains (MG5552, MG5405, MG5261, and MG5522) with GABA-producing ability from the 33 strains isolated from various fermented foods in South Korea.

Lactic acid bacteria have become popular because of their γ-aminobutyric acid (GABA)-producing ability. In the present study, we selected four Levilactobacillus brevis strains (MG5552, MG5405, MG5261, and MG5522) with GABA-producing ability from the 33 strains isolated from various fermented foods in South Korea. We evaluated their GABA-producing ability using thin-layer chromatography and determined the GABA levels produced by each strain using an amino acid analyzer. Moreover, we investigated the anti-inflammatory activity of the selected strains, and the results revealed that the cell-free supernatant of the strains decreased nitric oxide (NO), inducible nitric oxide synthase (iNOS) expression, and nuclear factor kappa B (NF-κB) activity in RAW264.7 macrophages. Therefore, these GABA-producing LAB strains can regulate nerve excitement and act as probiotics with anti-inflammatory activity. Full article
