Special Issue Information

Dear Colleagues,

Food fermentation is a major process in food processing, and many food products can be obtained through this process. Fermentation not only changes the physical properties of the original food material, but it is also an important process for the formation of food qualities such as nutritional composition and flavor. All these qualities ultimately influence the consumers’ choice. The structure of the microbial community during fermentation is the soul of this process, as it determines the course of the fermentation and the quality of the final product. Meanwhile, it is the diversity of the microbial community that determines the diversity of the fermented foods. The interaction between the microflora and food substrates in the fermentation process directly determines the food qualities. On the one hand, this interaction takes place as the microorganisms utilize the food matrix for growth and reproduction and secrete related metabolites to change the quality of the food; on the other hand, the structure and modification of the food matrix have an impact on the microbial community structure, which in turn determines the quality of the fermented food.

The aim of this Special Issue of Foods is to investigate the relationship between the microbial community structure and the product quality following fermentation. Studies investigating the microbial community structure and its changes not only in different food fermentation processes but also in correlation with food substrates are of great interest. In particular, it focuses on scientific issues such as the following: the microbiota and food nutrition; the microbiota and flavor; and the interconnections between different omics studies. This Special Issue welcomes original research articles and reviews on studies that address the above scientific questions or research methodologies. Clear and concisely written manuscripts are highly desirable and appreciated.

Abstract
In this study, four lactic acid bacteria (LAB) strains, including Lactiplantibacillus plantarum CICC21790, Lacticaseibacillus casei CICC6117, Lacticaseibacillus rhamnosus ATCC7469, and Limosilactobacillus fermentum CICC22704, were used to ferment a plant-based milk composed of chestnut and soybean. The fermentative characteristics of the four LAB strains [...] Read more.
In this study, four lactic acid bacteria (LAB) strains, including Lactiplantibacillus plantarum CICC21790, Lacticaseibacillus casei CICC6117, Lacticaseibacillus rhamnosus ATCC7469, and Limosilactobacillus fermentum CICC22704, were used to ferment a plant-based milk composed of chestnut and soybean. The fermentative characteristics of the four LAB strains and the aroma characteristics of the resulting plant-based milks were systematically investigated. The results showed that all four LAB strains successfully fermented the plant-based milk. The viable cell counts ranged from 7.67 to 8.57 lg CFU mL−1, and pH values were between 3.80 and 4.10. Comprehensive analyses performed using E-nose and HS-GC-IMS revealed distinct aroma characteristics in plant-based milks fermented by different LAB strains. Specifically, LAB fermentation, particularly by the CICC22704, significantly reduced the concentrations of aldehydes (e.g., hexanal, heptanal), thereby diminishing Green aroma characteristics. The increased concentrations of alcohols (e.g., 1-pentanol), ketones (e.g., 2, 3-butanedione) and furan compounds (e.g., 2-pentylfuran) in fermented plant-based milks enhanced Pungent, Creamy, and Fruity aroma characteristics, respectively. Fermentation by CICC21790, ATCC7469, and CICC6117 may result in stronger intensities of these three aroma characteristics compared to fermentation by the CICC22704. For the Fatty aroma characteristic, it was enhanced by CICC21790 fermentation but diminished by ATCC7469, CICC6117, and CICC22704 fermentations. Full article
