Method of manufacturing coffee extract allowing long-term preservation
First Claim
1. A coffee extract manufacturing method comprising the step of adding a strong alkaline salt to a coffee extract to modulate hydrogen ion concentration, in an amount to prevent precipitation or deterioration of the flavor resulting from long preservation and, at the same time, when said extract is filled into a sealed container, preventing occurrence of gas resulting from passage of time or heat sterilization which can cause expansion, deformation and breakage of the container.

Abstract
It is the object of the present invention to provide a coffee extract manufacturing method which prevents deterioration of flavor and precipitation in the coffee extract during long-term preservation and also keeps a sealed container filled with the coffee extract from expanding to deform or break for long preservation or heat sterilization. The invention is directed to a coffee extract manufacturing method allowing a long-term preservation, which has achieved the above object by adding strong alkaline salt that is alkaline noncarbonate into coffee extract.
