To provide a salty taste promoter usable as a substitution for table salt.SOLUTION: A fermentation product is produced by a fermentation treatment of milk, then, an enzyme treatment product is produced by performing a milk proteinase treatment without performing a germicidal treatment to the fermentation product, and then, a mixture in which potassium chloride is mixed into the enzyme treatment product as much as 5-20 wt% is produced, and thereafter, the mixture is subjected to a germicidal treatment, to thereby obtain a salty taste promoter.SELECTED DRAWING: Figure 1【課題】食塩の代替として使用できる塩味増強剤の提供。【解決手段】乳の発酵処理により発酵物を作製し、前記発酵物に対して殺菌処理を行わずに乳たんぱく分解酵素処理を行って酵素処理物を作製し、前記酵素処理物に塩化カリウムを５～２０ｗ％混合した混合物を作製した後、前記混合物を殺菌処理することにより得られる塩味増強剤。【選択図】図１
