明胶存在于胶原蛋白中，是一种具有高平均分子量的水溶性蛋白质的异质性混合物。 通过在水中将相关的皮肤、肌腱、韧带、骨骼等进行煮沸来提取蛋白质。 A类明胶来自于酸固化组织。 B类明胶来自于石灰固化组织。
Disclaimer
Dry gelatin, when stored in airtight containers at room temperature, will remain unchanged for many years. When heated at 100°C in the presence of air, it swells becomes soft and disintegrates to a carbonaceous mass with evolution of pyridine bases and ammonia.
