Tissue breakdown

In meats, the acid causes the tissue to break down, which allows more moisture to be absorbed and results in a juicier end product; however, too much acid can be detrimental to the end product. A good marinade has a balance of acid, oil, and spice. If raw marinated meat is frozen, the marinade can break down the surface and turn the outer layer mushy. Often confused with marinating,

macerating Maceration is the process of preparing foods through the softening or breaking into pieces using a liquid. Raw, dried or preserved fruit or vegetables are soaked in a liquid to soften the food, or absorb the flavor of the liquid into the food. I ...
