Industrial enzymes play a significant role in food processing, particularly in starch degradation.Amylases, a type of industrial enzyme, are used to break down starch into sugars. This process has numerous applications in the food industry, including the production of glucose syrup, bread, and beer.
A food processing company usesα-amylaseto hydrolyze starch into maltose. The reaction is as follows:
Starch →α-amylaseMaltose
A sample of starch solution (100 mL, 10% w/v) is treated with 0.1 g ofα-amylaseat 37°C for 30 minutes. The resulting maltose solution has a concentration of 5% w/v. Calculate the percentage conversion of starch to maltose.
| Step | Calculation |
| 1 | Initial starch mass: 10 g (100 mL × 10% w/v) |
| 2 | Maltose mass produced: 5 g (100 mL × 5% w/v) |
| 3 | Theoretical maltose mass (from 10 g starch): 10 g × (342/162) = 21.11 g (molecular weights: maltose = 342, starch = 162) |
| 4 | Percentage conversion: (5 g / 21.11 g) × 100% ≈ 23.67% |
