Bubbly tomato sauce?

Why was my jar of tomato sauce under pressure and the sauce bubbly? I had a half-full jar of tomato sauce that was closed and refrigerated. When opening the jar in order to use the sauce, the air pressure inside the jar was higher than the air pressure in the room and air escaped with a woosh, similar to opening a bottle of carbonated liquid (like seltzer.) Bubbles developed in the sauce in the jar, and a quick tasting of the sauce revealed that the sauce caused a sensation similar to carbonation. What was going on here?
