Study on Preparation and Application of High Esterification Green-Liquor Daqu

The optimal conditions of esterification Daqu production requires medium temperature to be used in the Daqu making process. The ratio of raw materials is 6:3:1 (wheat: barley: pea), the inoculation of Monascus (Monascus purpureus) FBKL3.0018 is 10 g/kg, and the water of Daqu is controlled at 40 %. The highest temperature is more suitable, which is controlled at 55 °C, and the culture time is 25–28 days. The best storage period of Daqu esterification is 2–3 months. This study could improve the quality of Daqu, the development, and research of fortified Daqu, which will become a hot point in increasing the quality rate of Luzhou-flavor liquor.
