A plant for heat treating heat-sensitive fluid foodstuffs an infusion chamber in which the fluid foodstuff is subjected to a heat treatment by a feeding of steam, and a fluid foodstuff inlet connected to a plurality of openings at the top of the infusion chamber for creating a plurality of essentially downwardly directed separate fluid foodstuff jets. The infusion chamber has a bottom section configured to collect the fluid foodstuff from the jets. The bottom section has an outlet opening at the bottom of the infusion chamber for allowing the collected fluid foodstuff to exit the infusion chamber. The outlet opening is seamlessly connected to the inlet of a pump. A cooling jacket surrounds the bottom section for cooling the bottom section. The cooling jacket extends all the way down to the pump.

Pasta sauce includes spicy seasoning, edible fat and oil, and at least one of ethanol or acetic acid. The pasta sauce may include 0.125 to 5.0% by weight of the ethanol and/or 0.0045 to 0.45% by weight of the acetic acid. A method for producing pasta sauce includes preparing a mixture by adding at least one of ethanol or acetic acid to a material solution containing spicy seasoning and edible fat and oil, and sterilizing the mixture by heating at a temperature lower than 100 C.
