|Title:||Studies on the degreasing of skin by using enzyme in liming process|
|Abstract:||This study has been conducted for the purpose of making the effective use of two enzymes viz. proteases and lipases for the removal of natural fat from the skin and increasing the effectiveness of degreasing; also decreasing the amount of chemicals used in degreasing and reducing the load of water treatment and eventually minimizing the harm that the leather industry poses to the environment. The optimum degreasing combination in which natural fat remains in the pelt at a level that could determine the efficacy of the enzymes was investigated. During the process of liming, enzymes such as alkali protease and alkali lipase were used alone and in combinations in varying amounts, and degreasing was achieved. Each experiment was processed till the end of tanning and effectiveness of the enzymes in degreasing was investigated. Results suggested that best degreasing conditions can be obtained with the use of 0.2% alkali lipase. The alkali lipases and the combinations of alkali proteases and lipases also proved to be satisfactory degreasing agents.|
