Description
Collagen breakdown through prolonged moist heat creates exceptionally tender pork texture.
Technical
Connective tissue collagen hydrolyzes into gelatin at 70-90°C through prolonged heating, while myofibrillar proteins denature to retain moisture. Maillard reactions occur during initial searing (140-165°C) creating flavor compounds like pyrazines and thiazoles.
Culinary Significance
The braising liquid (typically with Shaoxing wine and ginger) forms a flavor-infused gel matrix that coats the meatballs, while cabbage provides protective insulation and umami-enhancing glutamates.
