明胶制备

1.一般由新鲜牛奶经脱脂、加酸（乳酸、醋酸、盐酸或硫酸均可）凝固、干燥而制得。

新鲜牛奶→脱脂35～40℃沉淀↓酸(pH=46)→清洗→

甩水→干燥→成品

2.主要方法有石灰乳法和盐酸法两种制法。石灰乳法　将牛皮、猪皮等变质的下脚皮的内层油脂刮去，切块，放在3.0%～4.0%的石灰乳中浸泡30～40d，并经常搅拌，中间换石灰乳4～6次。浸泡后的生皮取出、洗净，在搅拌下用10%的盐酸中和3～4h，使pH值在6.0～6.5。然后按1;1加水，加热至60～70℃蒸煮，每隔一定时间抽取胶水。将稀胶水送入蒸发器浓缩，使相对密度为1.03～1.07。冷却、干燥，温度控制在28℃左右。粉碎得成品。

盐酸法　将碎骨在45～50℃下用苯提油后水洗，用3.5盐酸法　将碎骨在45～50℃下用苯提油后水洗，用3.5%～4.5%的盐酸浸泡软化得骨素粗品。水洗至pH值3.5左右，再用3.0%～3.5%的石灰乳浸泡30～50d，中间换石灰乳5～6次。取出后水洗，用0.2%盐酸中和至pH值3.5～4.0，放掉中和液另加清水，再用0.5%盐酸中和至pH值3.0。清水洗涤，浸泡4～5h，然后用稀氢氧化钠溶液洗涤，浸泡16～20h后用水冲洗，得到精制骨素。骨素在64～85℃下熬胶７道，得到的胶水经浓缩、干得明胶。

3.以动物皮、骨及结缔组织为原料,经提纯和初级水解后加工制得。
