Special Issue Information

Dear Colleagues,

The role of microorganisms in the transformation and conservation of foods has become progressively evident in recent years, resulting in an increasing interest in bacteria, yeast, and mold in the food industry. In addition, microbial metabolism could result in a nutritional enrichment of fermented food, as well as a tool to obtain functional foods. 

The aim of this Special Issue is to collect original research articles, as well as reviews articles, investigating the use of microbial cultures aimed at improving the organoleptic and nutritional properties of both traditional and innovative foods, as well as the use of microbial cultures for health purposes. Besides microbiology, there will be a particular focus on the biochemistry of fermentation. In particular, studies shedding light on the role played by the microbial pathways and/or specific enzymes on both pro-technological and food nutritional properties in several steps of production are strongly encouraged.

Kombucha is a sweetened tea infusion fermented using a symbiotic culture of bacteria and yeast (SCOBY). Recently, kombucha has gained popularity due to its potential health benefits, attributed to its high antioxidant and probiotic properties. The aim of this research was to formulate a novel antioxidant-rich beverage with symbiotic benefits by utilizing ingredients such as Laminaria digitata (brown seaweed), cinnamon, and lavender adjuncts, alongside alternative substrates like acacia honey and conventionally used ingredients such as ginger (Zingiber officinale Roscoe). This study comprehensively evaluated parameters including pH levels, acidity, alcohol content, color, and antioxidant potential of the beverages. All kombucha beverages exhibited significantly high antioxidant potential levels, particularly in Honey Kombucha (HK) samples, which ranged between 164.44 and 164.78% 2,2-Diphenyl-1-picrylhydrazyl (DPPH) inhibition, and 155.44–155.29 µg Trolox Equivalent (TE)/mL for the Ferric-reducing antioxidant power (FRAP) assay on days 3 and 7. Sugar Kombucha Seaweed (SKS) and Sugar Kombucha Cinnamon (SKC) samples received the highest acceptability for flavor from the sensory panel, with scores of 87.5% and 70%, respectively. However, Honey Kombucha Ginger (HKG) received the lowest acceptability with only 12.5%. The added adjuncts and substrates significantly influenced the antioxidant potential compared to plain unfermented tea (PT). This research paper outlines well-characterized fermentation process for formulating health-promoting beverages utilizing locally sourced ingredients. Full article

Nowadays, yeasts are widely used for food and beverage fermentation as well as for their functional traits, as there has been an increase in scientific interest in their contributions to human health. Microbial competition in habitats with adverse abiotic factors could force yeasts to activate competitive tools, such as bioactive compound production. Here, bee pollen, fresh bee bread, and aged bee bread were analyzed as a reservoir of potential new functional yeasts. Microbiological analyses of pollen showed a dominance of bacteria and molds, although yeasts were present in all samples and increased in fresh and aged bee bread where osmophilic yeasts appeared. Functional traits such as antioxidant activity; polyphenol and flavonoid production; antimicrobial activity toward molds, yeast, and pathogenic bacteria; phytase activity; and potential probiotic aptitude were studied. Out of fifty-eight isolated yeasts, four showed antioxidant activity higher (around 70%) than Codex® due to having the highest levels of polyphenols or flavonoids. One strain possessed phytase activity, and three strains belonging to Starmerella and Metschnikowia genera had wide antimicrobial activity. Nine strains exhibited the ability to resist gastrointestinal conditions, and four possessed all probiotic traits tested. All these findings demonstrate the effectiveness of pollen and bee bread as natural sources for new bioactive and functional yeasts. Full article

Introduction: Non-communicable chronic diseases, such as overweight and obesity, are considered a high risk for type 2 diabetes. Globally, there are 536.6 million people with diabetes. Mexico has a high prevalence of these diseases. Objective: The objective of this study was to evaluate the effects of a synbiotic beverage and a 12-week dietary intervention on body composition and biochemical parameters in women with T2D, overweight, or obesity as an additional strategy for treatment. Methods: This was a double-blind, randomized, and experimental study of a 12-week dietary intervention with a synbiotic fermented beverage with n = 51 women divided into four groups: G1 followed a moderate calorie-restricted diet, G2 followed the same moderate calorie-restricted diet and consumed a synbiotic beverage, G3 only consumed the synbiotic beverage, and G4 consumed a placebo beverage. Results: Significant changes were seen in BMI (p < 0.001) and fat mass (kg) (%) (p < 0.001) after the 12-week dietary intervention, proving that the synbiotic beverage had an effect on body composition. Conclusions: Significant decreases in different body composition and biochemical profiles were seen, showing the benefits of the beverage. A dietary intervention and the consumption of a fermented beverage could be an additional treatment for non-communicable diseases. Full article

This study examines the effects of artificial and mechanical production on the physicochemical properties, enzyme activities, flavor components, and microbial diversity of medium-high temperature Daqu, a crucial starter culture for Chinese Baijiu. The research aims to elucidate how these production methods influence the quality of Daqu and to provide technical insights for optimizing industrial production processes. Results demonstrate that artificial Daqu exhibits 0.24% higher reducing sugar content (p < 0.05), 8.3% greater water retention (p < 0.01), and a 0.10-unit increase in acidity (p < 0.05) compared to mechanically produced Daqu. In contrast, mechanically produced Daqu displays a greater liquefaction capability but reduced fermentation capacity. An analysis of volatile flavor compounds reveals that artificially produced Daqu contains a broader spectrum of aroma compounds, particularly esters and alcohols, which are critical for the flavor profile of Baijiu. Microbial analysis demonstrates that artificially produced Daqu possesses a richer diversity of bacterial and fungal communities, with dominant genera such as Aspergillus, Saccharomyces, and Lactobacillus playing a pivotal role in flavor development. These findings offer valuable insights for optimizing Daqu production methods, balancing traditional craftsmanship with modern industrial demands to ensure consistent quality and flavor in Baijiu production.

This study investigates the fermentation of white cabbage with salicornia and CaCl2 to assess its effect on the fermentation profiles and properties of the final products. Two sets of experiments were performed: A—cabbage with salt and salicornia, and B—cabbage with salt, salicornia, and CaCl2. The fermentative processes were studied through the microbial (lactic-acid bacteria (LAB), coliforms, and fungi), physicochemical (pH, total acidity), and mineral properties. A diminution of pH values (4.07, 3.58) and increased acidity values (0.70, 0.77 g lactic acid/100 mL) were registered at the end of the fermentation period (A and B, respectively). A stationary phase followed the exponential growth of LAB, and a slight decrease was observed (6.01, 5.51 Log CFU/g) in both experiments. A fungi decline was observed during the first week and the coliform populations disappeared after about 13 days of fermentation. Staphylococcus coagulase-positive, Escherichia coli, and Salmonella were not detected in the final products. The utilization of CaCl2 resulted in fermented cabbage with analogous microbial and sensorial characteristics to fermented cabbage without CaCl2 but with an increased hardness. However, Ca interfered with the diffusion of K, Mg, and Zn, resulting in lower levels of these elements in the final product, particularly Zn, which exhibited a reduction of 37%, reducing the nutritional value of the final products.

In recent years, wine producers have become increasingly interested in partial or total dealcoholisation of wines due to changing consumer preferences, increased attention to health aspects of alcohol consumption, and the impact of climate change on sugar concentration in grapes. Strategies for decreasing alcohol content in wines include pre-fermentation, fermentation, and post-fermentation techniques. These approaches allow for the reduction of fermentable sugars before fermentation, limit the alcohol production during fermentation, and separate alcohol after fermentation. From a biotechnological perspective, yeasts play a critical role in alcoholic fermentation, directly influencing the final alcohol content of the product. The use of non-Saccharomyces yeasts in co-inoculation or sequential inoculation with Saccharomyces yeasts represents a promising biotechnological strategy for the reduction of alcohol in wine.
