Question

Which enzyme is used for unhairing?

• A. Protease
• B. Amylase
• C. Lipase
• D. Glycosidase

Hint:

Protease is the enzyme that specifically targets the protein in the hair and breaks it down, aiding in the unhairing process in leather manufacturing.

Answer 1

The Correct Option is A

Step 1: Role of Enzymes in Unhairing
In leather processing, unhairing is a crucial step where the hair on animal hides is removed. This is achieved by using specific enzymes that break down the proteins in the hair follicles.

Step 2: Protease and Unhairing
- Protease is an enzyme that breaks down protein molecules. In unhairing, it breaks down the keratin in the hair and helps to loosen the hair from the hide.
- Amylase breaks down starches, lipase targets fats, and glycosidase works on carbohydrates, so they are not suitable for the unhairing process.

Step 3: Conclusion
Thus, protease is the correct enzyme used for unhairing in leather processing.
