Any kind of liquid that is used for soaking food in before cooking to add flavor is called a marinade. Common marinades include Italian dressing, wine marinades, etc and usually include at least one acidic ingredient (wine, vinegar, citrus).
In order that the flavours that the meat is being marinated in can be transferred to the meat.
Acetic acid--lots of marinades have vinegar in them.
Marinades usually contain some kind of acid, whether it be vinegar or citrus juice, which penetrate the meat with the help of the salt that is found in the marinade. The acid then begins to break down the connective tissue in the meat as it metabolizes the proteins.
Help break down protein to make the meat tender and add flavour
when meat is cooked it is a chemical reaction because you make it go back to its raw form hope that helps if not sorry
um
The acid in wine breaks down the proteins in meat, tenderizing it.
It begins when decomposers such as bacteria begin digesting the meat. Parts of the meat are broken down into nutrients that the bacteria can use, which can alter the initial chemical composure of the host body. As far as specifics, I do not know.
Well marinating meat in acid does two things, The acid of any marinate tenderizes the meat as well as alter the flavor.
no it is a physical change because you are just changing the size not the chemical structure
Because cooking involve chemical reactions, chemical changes, chemical transformations.
