PROBLEM TO BE SOLVED: To provide an amino acid-containing beverage production method that reduces offensive odors in a heat-sterilized product.SOLUTION: A first liquid is prepared by sterilizing a liquid containing beverage main ingredients at a high temperature of 121°C or higher in a short time of 1 minute or less under a condition where pH is 4.5-5.5. A second liquid is prepared by sterilizing an amino acid-containing liquid at a high temperature of 121°C or higher in a short time of 1 minute or less in the presence of a pH adjuster. The first and second liquids are individually cooled after the high-temperature short-time heat sterilization. An amino acid-containing beverage production method includes a mixing step of mixing the first liquid and the second liquid in a sterile environment to adjust pH to 5.2-7.0. The beverage component of the first liquid comprises a coffee extract, and the beverage component of the second liquid contains, based on the total amount of the beverage, 0.001-0.1 mass% of L-phenylalanine and/or 0.001-0.1 mass% of L-methionine.SELECTED DRAWING: None |
