Abstract: By accurately estimating the survival cell count in a probiotic product, the time for developing the product can be shortened. In a device (1) for estimating survival cell count, a calculation unit (14) calculates an estimated result of the survival cell count nt (CFU/g) of a specific strain contained in a composition after storage, in accordance with the following equation (I). (I) Log10nt=Log10n0?t×EXP{(AT×T+BT)w+(CT×T+DT)}, provided that t stands for the storage period (days)× 1/30, nt stands for the survival cell count (CFU/g) of the strain contained in the composition after the storage period t (days), n0 stands 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, AT and CT stand for experimentally determined coefficients specific to the strain, and BT and DT stand for experimentally determined constants specific to the strain.

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 nt (CFU/g) of a specific strain contained in a composition after storage, in accordance with the following equation (I).

Abstract: An agent for thermally stabilizing lactoferrin, which comprises a nucleic acid as an active ingredient, can be added to lactoferrin to impart thermal stability to lactoferrin. Thermally stabilized lactoferrin can be heat-sterilized at a pH value around a neutral pH value while keeping its activity.

Abstract: Disclosed is a disinfectant which is safe, has few adverse side-effects, can be ingested together with a food or beverage by adding the disinfectant to the food or beverage, shows a bactericidal effect in the oral cavity, and has no problem even when ingested on a daily basis over a long period. Also disclosed is a food additive comprising the disinfectant. Specifically, disclosed is an oral disinfectant for the disinfection of an oral bacterium, which comprises lactoperoxidase, glucose oxidase, glucose and a pH-adjusting component.
