Abstract

In this study, the flavour characteristics of the Chinese Rubing cheese produced through the traditional direct acidification (TRB) and fermented acidification technologies (FRB) were characterised by flavoromics. A total of eight and sixteen components were identified as the Characteristic Flavour Compounds (CFCs) of TRB and FRB, respectively. The CFCs of FRB were enriched in the methyl ketone, phenylalanine, methionine and leucine metabolic pathways, while the pyruvate metabolic pathway promoted the formation of CFCs of TRB. The partial least squares (PLS) analysis elucidated that benzaldehyde contributed to the milky and nutty aroma. Thus, the fermented acidification technology could be a potential approach for processing Rubing cheese.
