In the production of special-flavor liquor,a certain percentage of Monascus was added into fermentation pit in the distiller grains.The results showed that,when Monascus was applied,the maximum total ester content and total acid content increased by 52.81% and 39.4%,respectively,and alcohol content increased appropriately,while aldehydes content reduced.The special-flavor liquor style would not change,and it could be more perfect and harmonious.
