Q. Invertase 2. Fruit juice clarification
R. Pectinase 3. Liquefaction of sucrose
S. Xylanase 4. Pulp and paper processing
Show Hint
Memory trick: Amylase → detergents, Invertase → sugar, Pectinase → juice, Xylanase → paper.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
P. Amylase → 1. Laundry detergent
Amylases break down starch into smaller sugars and are widely used in detergent formulations to remove starchy stains from clothes.
Q. Invertase → 3. Liquefaction of sucrose
Invertase hydrolyzes sucrose into glucose and fructose (invert sugar), which is essential in confectionery and sugar processing industries.
R. Pectinase → 2. Fruit juice clarification
Pectinase breaks down pectin in plant cell walls, helping in fruit juice extraction and clarification by reducing viscosity and turbidity.
S. Xylanase → 4. Pulp and paper processing
Xylanase degrades xylan, improving pulp bleaching efficiency and reducing the need for harsh chemicals in paper industries.
Thus, the correct matching corresponds to option (B).
