PROBLEM TO BE SOLVED: To provide both a method for processed food preparation, in which an object raw material is brought into contact with an acid or an alkali, or a method for processed food preparation, in which after the contact treatment, the raw material is mixed with the aqueous solution of the acid or the alkali and/or another raw material and preserved, where the change of pH of the aqueous solution or the other raw material from a specific value, affecting the raw material, is avoided during or after the contact treatment. SOLUTION: This method for processed food preparation is characterized in that the object raw material is brought into contact with the acid or the alkali (hereinafter contact treatment) by using a pH buffer solution containing the acid or the alkali and a buffer substance having a pH buffer action on the acid or the alkali. |
