The problem to be solved by the invention is to provide a food or a drink containing an acidic protein which has a favorable flavor with relieved astringency characteristic to a protein dissolved under acidic conditions to thereby broaden the flavor variety of protein-containing foods or drinks. The above problem can be solved by adding a water soluble polysaccharide, a water soluble basic salt, an alkali metal salt of an organic acid, a basic monosaccharide, a basic oligosaccharide or the like to a food or a drink containing a protein dissolved under acidic conditions to thereby relieve the astringency originating in the protein dissolved under acidic conditions.

Acidic protein food or drink and material thereof

The present invention is intended to provide acidic gel foods containing soybean protein to diversify means of taking soybean protein in daily eating habits. Using the acid-soluble soybean protein as specified in the description, an aqueous solution or an alcohol-containing aqueous solution of the protein is adjusted to pH 3 to 4.5. Then an acid having 2 or more acid groups per molecule or its salt or a salt of another acid is added thereto and the mixture is heated to form a gel. Thus, acidic gel foods including a jelly-like food favorable as a food can be obtained.
