PROBLEM TO BE SOLVED: To obtain a milk coffee, distributable at normal temperatures, having flavor and acid taste close to those of a regular coffee and capable of stably maintaining milk ingredients. SOLUTION: This coffee containing milk comprises acidic polysaccharides and is obtained by regulating the pH thereof to about isoelectrlc point of a milk protein so as to provide pH 5.0-6.5 and further carrying out the homogenizing treatment and thermal sterilization. The coffee is prepared by regulating the pH of a milk coffee prepared solution obtained by blending a coffee extract solution with milk, acidic polysaccharides, etc., to about the isoelectric point of the milk protein or below that and reregulatlng the solution so as to afford pH 5.0-6.5 after the thermal sterilization, performing the homogenization treatment before and after that and then carrying out the thermal sterilization. |
