Special Issue Information

Dear Colleagues,

Fermented foods and beverages have long-standing traditional use across cultures worldwide. With advancements in modern science, research on the physiological roles of fermentation microbes, functional metabolites, and their impact on human health has gained significant attention. This Special Issue aims to explore the latest findings on microbial diversity in fermentation, bioactive compounds generated during the fermentation process, and their influence on food quality and human health.

We welcome original research and review articles on the following topics, but not limited to, the following:

  • Analysis of microbial diversity and dynamic changes during fermentation;
  • Investigation of metabolic products and bioactive compounds in fermented foods;
  • Nutritional and health benefits of fermented foods and beverages;
  • Innovations in fermentation technology using non-traditional raw materials;
  • Quality control and sensory analysis in fermentation processes.

This Special Issue seeks to provide insights into the intersection between microbiology, food science, and biotechnology, contributing to the advancement of fermentation research and its applications in the food industry.

This study aimed to identify kiwi kefir-like beverages with high levels of viable probiotic cells and low levels of calories, acids, and alcohol. To achieve this, microbiological and chemical characterizations were conducted on beverages inoculated with varying amounts of kefir grains (GW) and incubated at different agitation speeds (A), following a second-order orthogonal factorial design. For each experimental condition, three 24-h batch cultures were performed using three successive passages of kefir grains. Higher GW levels promoted greater nutrient consumption and metabolite production. However, an intermediate GW (1.80 g) resulted in the highest growth of lactic acid bacteria (LAB), acetic acid bacteria (AAB), yeasts, and free biomass in the fermented medium. Optimal agitation levels also enhanced nutrient consumption, free biomass, and metabolite pro-duction. AAB and yeast counts increased with higher agitation speeds, while LAB counts de-creased. Three beverages, produced during the second (A = 86 rpm, GW = 2.81 g) and third (A = 38 rpm, GW = 2.60 g; A = 86 rpm, GW = 1.80 g) kefir grain passages, exhibited LAB and yeast counts above 106; CFU/mL, along with low total sugar and ethanol concentrations. These beverages may be considered suitable as potentially probiotic, low-alcohol, and low-calorie functional drinks. Full article
