A high pressure processing system includes a pressure vessel configured to receive a basket or container, a high pressure pump configured to pump a pressure media to the pressure vessel to raise pressure in the pressure vessel, and a heater or cooler system, such as thermal jacket surrounding the pressure vessel, and the thermal jacket contains heat transfer media that is heated and cooled. The high pressure processing system, in addition to processing food stuff at a very high pressure of at least 2,000 bar also processes the food stuff at any high temperature of about 40° C. or greater.

An object of the invention is to provide a soy sauce which can be manufactured by a brewing process and which does not easily deteriorate by heating and has an excellent aroma-maintaining property and an excellent shelf life while having a flavor inherent in a soy sauce. The object is achieved by a pasteurized soy sauce containing 30 ppb or more of phenethyl acetate, a pasteurized soy sauce which contains 30 ppb or more of phenethyl acetate and in which the decrease rate of the phenethyl acetate after aging at 25° C. for one week is 5% or less, brewed pasteurized soy sauces thereof and the like.

A food processing vat is provided with a zoned heat transfer system that provides zoned temperature control to the vat. The zoned heat transfer system selectively transmits heat to or removes heat from different portions of a bottom wall and/or side walks) of the vat. A heat transfer fluid may be directed through the zoned heat transfer system along a flow path that is selected based on a target size and/or a target temperature of a batch of food product being processed in the vat.

A machine for the thermal treatment of liquid and semi-liquid food products includes at least two tanks for containing respective products to be subjected to the thermal treatment, at least one dispenser for dispensing the product contained in said tanks, at least one stirrer mounted inside each tank for mixing the product contained therein, and thermal treatment means operatively acting on the products contained in the containers. The thermal treatment means includes at least one circuit for circulation of an operating fluid and two first heat exchangers operating according to a thermodynamic cycle; each of the two heat exchangers being associated with a respective tank. The thermal treatment means is configured to implement at least one operating mode of removing heat from the respective tank by one heat exchanger and simultaneously transferring heat to the respective tank by the other heat exchanger.
