Abstract:
1. A method for producing a high-zinc-content yeast extract, comprising: hot-water treating of zinc-containing yeast by suspending the zinc-containing yeast into hot-water having a temperature in a range from 60° C. to 120° C. so as to obtain a first suspension liquid, and separating a first solid component and a first liquid component of the first suspension liquid so as to obtain the first solid component; and extracting the high-zinc-content yeast extract by suspending the first solid component obtained in the hot-water treating step into a solution containing a carboxylic acid, a carboxylic acid salt, or both thereof so as to obtain a second suspension liquid, and separating a second solid component and a second liquid component of the second suspension liquid so as to obtain the second liquid component containing the high-zinc-content yeast extract.
