Monascus vinegar (MV), during whose brewing process Monascus spp.and polished rice (PR) are normally used as the starter and the raw material, respectively, is one of the traditional vinegars in China.In this study, the effects of three raw materials, including PR, unhusked rice (UR), and bengals dog collar germinated UR (GR), on MV volatile compounds have been investigated.The results revealed that MV of GR (GMV), and its intermediate Monascus wine (GMW), exhibited the highest amount of aroma, not only in the concentrations but also in the varieties of the aromatic compounds mainly contributing to the final fragrance.Especially after three years of aging, the contents of benzaldehyde and furfural in GMV could reach to 13.

93% and 0.57%, respectively, both of which can coordinate synergistically on enhancing the aroma.We also found that the filtering efficiency was significantly improved when UR and GR were applied as the raw materials, respectively.Therefore, layer cake chardonnay 2020 GR might be more suitable raw materials for MV.
