PROBLEM TO BE SOLVED: To provide reduced-salt food and drink which are reduced in salt content by adding a salty taste enhancer to food and drink reduced in salt to enhance salty taste.SOLUTION: In the salty taste enhancement method and salt reducing method for salt-containing food and drink, a salty taste enhancer mainly including phenylpropionic acid 2-1,500 ppb, particularly preferably, 20-200 ppb as a salty taste enhancing component is added to salt-containing food and drink with reduced salt, for example, a 20% reduced-salt noodle source, whereby the amount of salt used can be reduced without impairing palatability of food and drink or original flavor balance of salt-containing food and drink and without unpleasant taste such as stringent taste, bitter taste, sweet taste or pungent taste. The methods can be used also for seasoning or cooking. Further, the method can be applied to various types of food and drink from the viewpoint of taste property, effect, economic efficiency, safety and the like in addition to salty taste enhancement effect.COPYRIGHT: (C)2013,JPO&INPIT【課題】減塩した飲食品に塩味増強剤を加え、塩味を増強させることで食塩含有量を減らし、減塩飲食品を提供する。【解決手段】減塩した食塩含有飲食品例えば20%減塩しためんつゆに塩味増強成分としてフェニルプロピオン酸2~1500ppb、特に好ましくは20~200ppbを主成分とする塩味増強剤を加えることにより、飲食品のおいしさや食塩含有飲食品が本来有する風味のバランスを損なうことなく、用いる食塩の量を減らすことができ、渋味、苦味、甘味、辛味などの異風味もなく、食塩含有飲食品の塩味増強法、減塩方法、調味または調理にも使用できる。そして塩味の増強効果に加えて、嗜好性、効果、経済性、安全性等の点から多種の飲食品に使用できる。【選択図】なし
