Food product preservation method

This invention describes a way to preserve food, particularly vegetables, so it tastes and looks better than frozen options. The process involves putting food into a sealed container, adding a precise amount of edible acid to make it slightly acidic (pH 4.6-5), heating it to pasteurize, quickly cooling it down, and then storing it in a refrigerator.

Why it matters: Since 2003, consumer demand for high-quality, convenient refrigerated meals has surged. Advances in food processing and packaging technology now make it easier to consistently deliver the claimed superior appearance, texture, and taste for preserved foods.
