Abstract: Using Monascus sp. as a vacuum freeze-drying strain, the effect of different protective agents on the survival rate of Monascus spores was studied through a single factor experiment. Based on this, the optimal protective agent group was selected through orthogonal experiment optimization as sucrose addition 14%, lactose addition 3%, and trehalose addition 7%. The validation test showed that the survival rate of Monascus sp. after freeze-drying with the protective agent formulated with this formula reached 78.47%.

Keywords: Monascus sp.; protective agents; survival rate
