Уважаемый Simon, aging meat -это мясо кот.дают подгнить слегка чтоб оно стало мягче..
Я этого не ем и всем не советую..И даже слов Postmortem(или трупное разложение по русски) кот.употребляются в криминальной литературе не люблю..И то что подается в ресторанах как нежный деликатес,на самом деле 11 дневное гнилье...

Postmortem aging, sometimes called "conditioning" or "ripening," is a natural process which improves the palatability attributes of meat, especially cuts from the rib and loin. Commercially, postmortem aging is accomplished by subjecting carcasses, primal or subprimal cuts to controlled, refrigerated (
above freezing) storage conditions. Of the palatability attributes of beef steaks, tenderness is the attribute most demanded by consumers, and the improvement in tenderness is the primary reason for postmortem aging. Postmortem aging, however, also improves the palatability attribute of favor.
Primal or subprimal beef cuts from the loin and rib (middle meats) are specifically aged post-mortem, since these serve as the source desirable steaks (rib, T-bone, Porterhouse, top loin, sirloin and filet mignon steaks).
(While carcasses or cuts from any species could be aged, postmortem aging is generally limited to beef, due to the relative youth of pork, lamb and veal. Consequently, this discussion concentrates on the postmortem aging of beef.)
Postmortem Aging?
Postmortem aging is a process that occurs naturally in all muscle tissues, whether vacuum packaged or in the form of carcasses or wholesale cuts. In the conversion of muscle to meat, natural enzymes (proteases) found in muscles,
breaks down specific proteins in muscle fibers (a process called proteolysis). This breaking (or fragmentation) of these protein strands, called myofibrils, by natural enzymes results in improved tenderness of the rib Tenderization occurs o1 a relatively rapid rate until 3 to 7 days postmortem, and then the rate of increased tenderness diminishes with time. Practically speaking, the increase in tenderness of rib and loin muscles during postmortem aging. Tenderization occurs at a relatively rapid rate until 3 to 7 days postmortem, and then the rate of increased tenderness diminishes with time. Practically speaking, the increase in tenderness of rib and loin cuts after 7 to 10 days is relatively small, compared with the increase during the first 7 to 10 days postmortem.
Dry Aging.
The old method of aging meat is known as dry aging. Dry aging is done by hanging meat in a controlled, closely watched, refrigerated environment.
The temperature needs to stay between 36 degrees F and freezing. Too warm and the meat will spoil, too cold and it will freeze, stopping the aging process. You also need a humidity of about 85 to reduce water loss.
To control bacteria you need a constant flow of air all around the meat, which means it needs to be hanging in a well ventilated space. The last and most important ingredient in this process is an experienced butcher to keep a close eye on the aging meat.
There are many reasons that butchers don't typically age meat these days. First of all the cost of aged beef can be very high. Because of the weight loss of aged beef, the price per pound can be pretty outrageous. If you add in the time, storage space, refrigeration, labor that price just keeps moving up.
Aging takes about 11 days before you see much improvement in the flavor of the meat. After that the flavor continues to intensify, but so does the loss of weight and the risk of spoilage. Eventually the meat will be worthless so many fine restaurants who do their own aging will limit it to 20 to 30 days.
