, except that pickling is generally done for much longer periods of months or even years, primarily as a means of food preservation. Conversely, marinating is usually performed for a few hours to a day, generally as a means of enhancing the flavor of the food or tenderizing it. Marinades vary between different cuisines. The French word derives from the verb "to pickle in sea brine", and ultimately from the Latin noun "sea", suggesting that marinades may have evolved from an ancient brining tradition or may have initially used sea brine as an ingredient.

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. ...

which may contaminate the marinade. Marinating should be done in the refrigerator to inhibit bacterial growth. Used marinade should not be made into a sauce unless rendered safe by boiling directly before use; otherwise, fresh or set-aside marinade that has not touched meat should be used. The container used for marinating should be glass or food safe plastic. Metal, including pottery glazes which can contain lead, reacts with the acid in the marinade and should be avoided.
