Abstract
The present invention provides a method for estimating survival cell count, which is able to calculate an accurately estimated result of the survival cell count of a specific strain in a probiotic product with respect to its storage period, and to shorten the time for developing the product, and a method for setting a guaranteed cell count, which is able to readily calculate a guaranteed cell count of a specific strain in a probiotic product within its quality guarantee period. The method for estimating the survival cell count is characterized by estimating the survival cell count n(CFU/g) of a specific strain contained in a composition after storage, in accordance with the following equation (I). (I) Logn=Logn−t×EXP{(A×T+B)w+(C×T+D)}, provided that t stands for the storage period (days)×1/30, nstands for the survival cell count (CFU/g) of the strain contained in the composition after the storage period t (days), nstands for the viable cell count (CFU/g) of the strain contained in the composition at the initiation of storage, T stands for the storage temperature (° C.), w stands for the water activity value of the composition, Aand Cstand for experimentally determined coefficients specific to the strain, and Band Dstand for experimentally determined constants specific to the strain.
