Assessment of Metabolites in Noni Fruit Slurry Fermented With Four Non‐Saccharomyces Yeasts

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
Dried noni fruit slurry (DNFS) was fermented for 14 days with selected non‐Saccharomyces yeasts. GCMS, HPLC and amino acid analysis showed that Pichia kluyveri Frootzen and Williopsis saturnus NCYC22 grew well, reduced off‐flavor fatty acids, generated fruity aroma compounds and preserved total phenolic content. ABSTRACT Noni products often suffer from

Mechanism of Alfalfa in Enhancing Goose Egg Yolk Flavor: An Analysis Based on Metabolomics and Quantitative Lipidomics

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
ABSTRACT Organic egg production requires daily provision of coarse feed, fresh or dried forage, and silage to poultry. This study employed flavoromics, metabolomics, and quantitative lipidomics to investigate the effects of replacing 0% (CK), 10% (T10), and 20% (T20) of the basal diet of laying geese with alfalfa (Medicago sativa L.) on the sensory ...
