Laboratory study reveals enhanced antioxidant capacity and improved flavor profiles in fermented coffee pulp beverages, suggesting high-value opportunities for functional food development.

Key Points

To assess how single-strain fermentation with four probiotic strains impacts the antioxidant properties, flavor volatile profiles, and non-volatile metabolites of coffee pulp beverages.
Fermented coffee pulp beverage using four bacterial strains: Bifidobacterium longum BL11, Streptococcus thermophilus LB42, Lacticaseibacillus casei LC15, and Lactiplantibacillus plantarum XJ25.
Profiled volatile organic compounds using HS-SPME-GC-MS and GC-IMS, and quantified differential non-volatile metabolites, antioxidant capacity, and sensory acceptability.
Fermentation significantly increased antioxidant activities across all samples (p < 0.05) and yielded 37 newly formed volatile compounds, including esters, alcohols, and ketones.
Identified 334 differential non-volatile metabolites across 20 subclasses (p < 0.05), led by organic acids and amino acid derivatives, with Lactiplantibacillus plantarum yielding the highest overall sensory acceptability.
