PURPOSE: To obtain the beverage capable of suppressing the growth of thermostable microorganisms by mixing and homogenizing a low-acidic beverage content liquid containing milk without containing a sucrose ester of a fatty acid, heat-treating the resultant homogenate under specific conditions, then filling the heat-treated beverage in a container, hermetically sealing the container and carrying out the retort heat treatment. CONSTITUTION: This method for producing a low-acidic beverage filled in a hermetically sealed container is to mix cow's milk with granulated sugar, a skimmilk powder, a powdery coffee, sodium bicarbonate and water treated with active carbon, prepare a low-acidic beverage content liquid containing the milk without containing a sucrose ester of a fatty acid, carry out the heat treatment with a heat exchanger before or after performing the homogenizing treatment with a homogenizer, etc., then fill the resultant liquid in a container at <=35 deg.C filling temperature with a filler, replace air in the container with steam or a mixed gas of the steam with nitrogen gas, hermetically seal the container and subsequently perform the retort heat treatment. The sum total of the F0 value for the heat treatment with the heat exchanger and the retort heat treatment (heating time required to kill all the microorganisms) is >=120. The resultant beverage is capable of suppressing the germination and growth of thermostable microorganisms even by heating and selling thereof with an automatic vender, etc. |
