Meat has several types of con- nective tissue, including collagen and elastin. Collagen (=k&-l`-j`n) is the thin, white, trans- parent connective tissue found in tendons, between muscle cells, and between muscles. When cooked in moist heat, collagen softens and turns into gelatin.
Which type of connective tissue can be tenderized by moist heat cooking methods?
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. Collagen is soluble in water and when it is cooked slowly with moist heat, it becomes gelatin.

What happens to connective tissue when meat is cooked?
A softer connective tissue called collagen is scattered throughout the muscle, often surrounding fibers and sheaths holding them together. When you cook, collagen melts and turns to a rich liquid called gelatin , similar to the stuff Jell-O is made from.
Will lemon juice help reverse coagulation in overcooked proteins?

What is the significance of connective tissues to live animal cooking and eating quality of meat?

What kind of connective tissue that is white and dissolve or break down by long slow cooking with liquid?
There are two kinds of connective tissue: collagen , which is white in color, and elastin, which is yellow. Collagen. Long, slow cooking in the presence of moisture breaks down or dissolves collagen by turning it into gelatin and water.
