Study on a Lyophilization Protective Agent for Spores of Monascus sp.
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%.
