Special Issue Information

Dear Colleagues,

Fermentation is one of the oldest and most economical ways of producing and preserving food through desired microbial growth and enzymatic conversions of food components, such as soy sauce and fermented bean curd in China, Kimchi in Korea, or bread and cheese in many Western countries. It is well known that fermentation is a process that harnesses naturally occurring molds (Aspergillus and Rhizopus), yeast (Candida and Hansenula), and bacteria (lactic acid bacteria and thermostable Bacillus) as well as cultivated strains to biologically convert complex components into simper ones. Fermented foods exhibit health-beneficial effects by regulating gut microbiota, strengthening immune system, and so on.

Currently, starter culture development is vital to the industrial production of fermented foods and can control the communities of microbes during fermentation, standardize product quality, and reduce the risk of fermentation failure. Hence, high-throughput sequencing technology, gene editing technology, omics analysis technology, etc., have emerged for application to select strains, thereby increasing the fermentation rate, product flavors, and nutritional values.  

Therefore, this Special Issue will include manuscripts focusing on “Fermented Foods: Microbiology, Technology, and Health Benefits”, which are of great significance to the food industry’s development.

This Special Issue will cover a wide range of research topics, including but not limited to the following:

  • Analysis of microbial metabolism by multi-omics data during fermentation.
  • Designation of synthetic microbial communities to improve the quality of traditional fermented foods.
  • Identification of key functional constituents in animal- or plant-based fermented foods.
  • Underlying molecular mechanisms and health benefits of fermented foods.
  • Microbial interactions during food fermentation.
  • Application of probiotic microbes in fermented foods.
  • Identification of key enzymes in the process of food fermentation.

I/We look forward to receiving your contributions.

Lactic acid bacteria fermentation is a beneficial bioprocessing method that can improve the flavor, transform nutrients, and maintain the biological activity of foods. The aim of this study is to investigate the effects of Lactiplantibacillus plantarum dy-1 fermentation on the nutritional components, flavor and taste properties, and composition of saponin compounds and their hypolipidemic and antioxidant activities. The results suggested that the total polyphenol content increased, and the soluble polysaccharides and total saponin contents decreased in fermented bitter melon juice (FJ) compared with those in non-fermented bitter melon juice (NFJ). The determination of volatile flavor substances by GC-MS revealed that the response values of acetic acid, n-octanol, sedumol, etc., augmented significantly, and taste analysis with an electronic tongue demonstrated lower bitterness and higher acidity in FJ. Furthermore, UPLC-Q-TOF-MS/MS testing showed a significant decrease in bitter compounds, including momordicines I and II, and a significant increase in the active saponin momordicine U in the fermented bitter melon saponin group (FJBMS). The in vitro assays indicated that FJBMS exhibited similar antioxidant activities as the non-fermented bitter melon saponin group (NFBMS). The in vitro results show that both NFBMS and FJBMS, when used at 50 μg/mL, could significantly reduce fat accumulation and the malondialdehyde (MDA) content and increased the catalase (CAT) activity, while there was no significant difference in the bioactivities of NFBMS and FJBMS. In conclusion, Lactiplantibacillus plantarum dy-1 fermentation is an effective means to lower the bitterness value of bitter melon and preserve the well-known bioactivities of its raw materials, which can improve the edibility of bitter melon.
