Special Issue Information

Dear Colleagues,

Food fermentation is an ancient biotechnological process, but given its variety of applications, it remains current. Since its adoption, it has been used for food preservation; however, it is increasingly becoming a useful tool to improve the sensory, nutritional, and/or health properties of foods, enabling the production of functional variants. It is also employed in the production of nutraceuticals, biochemicals, food ingredients, and enzymes, and it can be considered a sustainable process as it can facilitate the valorization of agri-food waste. Optimizing the efficiency of the fermentation process and its broader usefulness—for example, regarding expected health or technological impacts—depends mostly on the selection of the strain and the food substrate to be fermented, as well as other chosen process parameters.

This Special Issue aims to gather the latest knowledge on food fermentation, focusing on advanced methodologies and applications. Potential topics include but are not limited to

  • Advanced methodologies to identify, enumerate, and characterize microorganisms in fermented foods;
  • Advanced methodologies for fermentation processes and the development of novel foods;
  • Scientific evidence of the impacts of fermented foods on human health;
  • Research on the valorization of agri-food waste through fermentation;
  • The engineering of microorganisms for improved or targeted production of specific metabolites.

Original works, review papers, and comparative studies are all welcome.

Postbiotics, a type of fermented functional food, are attracting attention alongside the more common pro- and prebiotics. The main production stages—fermentation, thermal inactivation, and drying—significantly influence the functional effects of these foods. This study investigated the impact of pH control during the fermentation of oat flour suspension and optimized spray-drying parameters to produce oat-based postbiotic powders. A Lacticaseibacillus paracasei CBA L74 fermented hydrolyzed oat suspension was analyzed at 37 °C for 24 h, with and without pH control. Both pH conditions produced similar bacterial growth (~109 CFU/mL) and lactic acid (~9 g/L). No significant differences were observed in polyphenols, flavonoids, or antioxidant activity, indicating that pH control did not noticeably improve productivity or the phytochemical properties. The best results—57.40% drying yield and 3.9% relative humidity—were achieved when the postbiotic suspension (diluted 1:4 with water) was mixed 1:1 with maltodextrins, and the spray drying process was conducted with 50 L/min air flow, 200 °C, 3.2 bar atomization pressure, and 5 L/min feed flow. These results support the possibility of scaling the production process from laboratory-optimized parameters and represent a first step toward a cost-effective and industrially feasible route for manufacturing stable oat-based postbiotic powders.
