摘要
[Objective] This study was conducted to optimize rice making process and improve the content of Monascus pigment. [Method]Selecting water addition( A),sterilization temperature( B),sterilization time( C),soaking time( D) as experimental factors,L_9( 3~4) orthogonal test was carried out to optimize rice making process. [Result] The four factors all had very significant effect on the yield of Monascus pigment,the optimal combination was A_1B_2C_2D_2,namely water addition of 30 ml,sterilization temperature at 121 ℃,sterilization time of 23 min,and soaking time of 24 h. The level of Monascus reached 2 884 U/g under this condition. [Conclusion] The study has great practical significance to Monascus rice production enterprises.
