Aug 01, 2006 · By its very composition, meat poses a challenge to cooks. The more you cook muscle, the more the proteins will firm up, toughen, and dry out. But the longer you cook connective tissue, the more it softens and becomes edible. To be specific, muscle tends to have the most tender texture between 120° and 160°F.
The more collagen there is in a piece of meat, the tougher it is to cut and to chew. Skin is mostly collagen, as are the tendons that connect muscles to bones. For cuts that are high in collagen, cooking with methods that use slow, moist heat, such as stewing or braising, are the best.
Various proteins in meat fibers coagulate over a range of temperatures from 105 F/40 C to 195 F /90 C temperatures that are far below boiling point (212 °F/100 °C). The higher the cooking temperature, the tougher the muscle fibers become, and the more they shrink in …
Why is meat still tough in the slow cooker? It’s because you haven’t let the collagen break down. Extend the cook time, make sure there’s enough liquid and keep an eye on the dish. Does meat get more tender the longer you cook it in a slow cooker? Not if you’re using a leaner cut in the slow cooker, like chicken breast or pork chops.
Yes, there are scientific reasons to back up the fact that slow cooked meat is better. Tenderness in meat comes from the melting of collagen – the connective tissue protein present in meat. When collagen melts, it turns into gelatin, a rich liquid that gives meat a lot of flavour as well as a silky texture.Nov 2, 2017

The moist heat they provide softens the connective tissue that binds the muscle fibers in the meat, helping it to fall apart more easily. And when the heat is kept low, as it is in slow cooking, the proteins in the muscle are less likely to overcook, so the meat stays moist as well as tender.
As the temperature increases so does the speed of tenderization. Below about 140°F (60°C) the meat is tenderizing much more quickly than it is contracting, resulting in minimal moisture loss. Holding meat at a lower temperature means that you can tenderize the meat without losing much moisture.
When heat is applied to meat, two general changes occur: muscle fibers become tougher and connective tissue becomes more tender. During cooking, actin, myosin and other muscle fiber proteins undergo changes.
Additionally, overcooking meat, even meat that comes from the more tender muscles, can make it tough. That's because heat causes the proteins in the meat to firm up. Overcooking also basically squeezes the moisture out of the meat, making it dry as well as tough.Jun 26, 2019

Cooking meat does not make it tough, it gets more tender. Meat does get dry at higher temperatures, time does not matter that much. The higher the temperature the more moisture is squeezed out of the meat making it more dry, I guess that it what you describe as tough.Nov 20, 2012
If it's a leaner cut, then low and slow and long will lead to dry and stringy meat (not good eats). Cooking meat longer makes it more tender by breaking down collagen/connective tissue into gelatin.Oct 26, 2016
You can cook on high or low — there's no in-between. So what's the best choice for scrumptious slow cooked meals? As the saying goes, less is more. According to Jack Bishop of America's Test Kitchen, using the high setting on the slow cooker has the potential to ruin a dish.Dec 10, 2020
Some people worry that cooking foods at a low temperature for a long time in a slow cooker or in a slow oven is unhealthful. But it's OK. Cooking meat for four hours at 250 degrees does not present a health risk and will not "incubate" bacteria.Mar 25, 2009
