Special Issue Information

Dear Colleagues,

Microbial fermentations, which have mainly been used to preserve raw plant and/or animal matrices, are today increasingly used to improve the organoleptic features, shelf-life and health properties of fermented foods. Numerous microorganisms, through their metabolic activity, can improve the flavour and nutritional and health properties of fermented foods and beverages. Consequently, scientific and industrial interest is increasingly directed towards microbe-driven fermentations for the formulation of new fermented foods and beverages with safe, healthy and functional properties.

Despite the many favourable properties of fermentation and the microorganisms traditionally used in food fermentation, there are still process optimisation problems that need to be overcome. Optimising fermentation procedures is necessary in order to identify the best processing conditions that increase the yield of a production process and lead quality characteristics in the desired direction.

Therefore, we invite you to submit your recent research in this area to this Special Issue of Foods entitled “Process Optimization and Quality Improvement of Fermented Foods and Beverages: 2nd Edition”, which aims to cover recent studies addressing technological, microbiological, biochemical, nutritional and health aspects for the delivery of better, safer and more cost-effective fermented food products and beverages.

Fermentation is a crucial stage in the production of washed mild coffees, as it enables the generation of compounds that influence overall quality. The conditions to optimize this process are still unknown. This study evaluated the effects of fermenting coffee fruits and depulped coffee under two conditions: an open tank (semi-anaerobic-SA) and a closed tank (self-induced anaerobic fermentation, SIAF) over 192 h. Samples were taken every 24 h using a sacrificial bioreactor. A randomized complete block design with a factorial arrangement (2 × 2 + 1), plus a standard control, was employed, incorporating two factors: coffee type and fermentation condition. High-throughput sequencing of 16S and ITS amplicons identified an average of 260 ± 71 and 101 ± 24 OTUs, respectively. Weisella was the dominant lactic acid bacteria, followed by Leuconostoc and Lactiplantibacillus. Acetic acid bacteria, mainly Acetobacter, were more abundant under semi-anaerobic conditions. The yeast genera most affected by the fermentation condition were Pichia, Issatchenkia, and Wickerhamomyces. Repeated measures analysis revealed significant differences in pH, glucose consumption, lactic acid production, dry matter content, embryo viability, and the percentage of healthy beans. Principal component analysis was used to develop an index that integrates physical, physiological, and sensory quality variables, thereby clarifying the impact of each treatment. Samples from shorter fermentation times and SIAF conditions scored closest to 1.0, reflecting the most favorable outcomes. Otherwise, samples from longer fermentation times in both depulped and coffee fruits scored 0.497 and 0.369, respectively, on the SA condition. These findings support technically and economically beneficial fermentation strategies. Full article
