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&#xb0; 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.

Method of producing yeast extract

The present invention relates to an effective sterilization method including cooking and heating processes, which prevents the quality deterioration of rice and processed rice foodstuffs manufactured by heating processes.

Sterilization method of rice and processed rice foodstuffs

Apparatus for continuously pasteurizing liquid by continuously flowing the liquid within a high electric field, comprises a body of electrical insulator material forming a wall, opening portions formed in the wall body as passages for the liquid therethrough, at least a pair of electrode wires laid across the opening portions, and a mechanism for applying an alternating current voltage across the pair of electrode wires. Joints and pipes may be connected to the wall body and together with the opening portions define a fluid passage through which the liquid continuously flows for being pasteurized. A method of continuous liquid pasteurization using the apparatus involves applying an alternating current voltage between the pair of electrode wires under the conditions of 2000.ltoreq.H/d.ltoreq.200 where d (mm) is the distance between the wires and H (volt) is the voltage applied thereacross, and such that the liquid is heated.

Continuous liquid pasteurizing apparatus and a method therefor

A continuous liquid pasteurizing apparatus and method for effectively pasteurizing microbes or bacteria having heat-resistance and/or pressure-resistance, such as sporangium, with low temperature or by maintaining a high temperature for a short time, wherein an electricity conducting unit (9) for pasteurizing the liquid is provided within a pressurized container (1), and an upper end portion of the electricity conducting unit(9)is connected to a supply opening (3)for liquid, while a lower end portion thereof is connected to a reservoir portion(10)which is cooled by a cooling mechanism involving heat exchange with cooling water(7). The thus-pasteurized liquid is reserved in a reservoir portion (10)and is taken out from an outlet opening(4)through a conduit (11)outside the container(1).
