Alkaline lipase Greasex 50L is one of the leather enzyme products of Novo Nordisk AS. After extensive control trials on pigskins, evaluating effects by degree of fat removal and qualities of result leather, we got1 Fat removal rate can be increased by 10%and leather qualities such as napping and softness can be improved by using Greasex 50L together with liming enzyme NUE 0.6 MPX2 Some surfactant together with Greasex 50L is good to fat removal, and the recommended ratio is 0.05%～0.1%∶13 The fat content in the skins is lower after treated with Greasex 50L,which also benefits the successive processes, such as bating, pickling and tanning. As a result, the leather qualities, such as fineness of grain, softness, napping and evenness of dyeing can be improved.

Greasex 50L是诺和诺德公司生产的碱性脂肪酶已在皮革工业中广泛使用，为了更好地应用这种酶制剂，我们对Greasex 50L在猪皮方面的应用条件进行了研究采用对比的方法，用脂肪去除率和皮革的质量作为评价标准，研究结果表明1适量的浸灰酶 NUE 0.6 MPX可使Greasex 50L的脱脂率增大，同时可改善皮革的起绒状况和革身柔软性2一定量的表面活性剂与Greasex 50L配合使用，有利于脂肪的去除，用量为平平加的0.05%～0.1%3 经Greasex 50L脱脂的裸皮在鞣制后油脂含量也较低，有利于后续工序进行，从而使成革粒面平细、革身柔软，臀部起绒得到改善，染色均匀性良好
