Effects and mechanisms of various distiller's grains on volatile organic compounds in fermented pigeon meat.

ABSTRACT: To understand the relationship between volatile organic compounds (VOCs) and metabolites in pigeon meat fermented with different distiller's grains (glutinous rice, GD group; sorghum, SD group; and oat, OD group), this study analyzed the fermented pigeon meat through flavoromics and metabolomics and predicted the pathways of VOCs formation. Ethanol was the main difference among treatment groups. Meanwhile, 1-octen-3-ol, ethanol, ethyl lactate, and 2,5-octanedione were the characteristic VOCs in the CK, GD, SD, and OD groups, respectively. Non-targeted metabolomics identified 2035 metabolites, with amino acids, peptides, and analogs being the most abundant category. KEGG pathway analysis revealed 13 key metabolic pathways which were critical to flavor formation. Alanine, glucose, and galact
