  • Method of producing yeast extract
    Patent number: 10557131
    Abstract: A yeast extract is produced by preparing a suspension containing yeast, applying an electric field treatment to the suspension, and then autolyzing the suspension. In this electric field treatment, a voltage to be applied is less than 1000 V/mm, and a temperature of the suspension during an application period of the voltage is 64° C. or less. According to such a production process, a content of amino acids in the yeast extract can be improved. Among amino acids, branched chain amino acids or the like can be efficiently increased.
    Type: Grant
