Enzymatic Hydrolysis of Starch
Objective:

To demonstrate the enzymatic hydrolysis of starch into glucose syrup using the enzyme glucoamylase.


Materials:

  • Soluble starch
  • Glucoamylase enzyme
  • pH buffer (pH 4.5)
  • Water bath
  • Spectrophotometer
  • Glucose standard

Procedure:
Step 1: Prepare the enzyme solution

  1. Weigh out 0.1 g of glucoamylase enzyme.
  2. Dissolve the enzyme in 100 mL of pH 4.5 buffer.

Step 2: Prepare the starch solution

  1. Weigh out 1 g of soluble starch.
  2. Dissolve the starch in 100 mL of water.

Step 3: Set up the reaction mixture

  1. Mix 10 mL of the starch solution, 10 mL of the enzyme solution, and 80 mL of buffer in a water bath.
  2. Maintain the temperature at 50°C.

Step 4: Monitor the reaction

  1. Take samples from the reaction mixture at regular intervals (e.g., 0, 15, 30, 60 minutes).
  2. Stop the reaction by adding 1 mL of 0.1 N NaOH.
  3. Measure the absorbance of the samples at 540 nm using a spectrophotometer.

Step 5: Determine the glucose concentration

  1. Prepare a glucose standard curve by measuring the absorbance of known glucose concentrations.
  2. Use the standard curve to determine the glucose concentration in the samples.

Results:

The absorbance values obtained will increase over time, indicating the production of glucose. The glucose concentration can be determined using the standard curve.


Significance:

This experiment demonstrates the use of enzymes in industrial biochemistry. Glucoamylase is used in the production of glucose syrup, which is a widely used sweetener in the food industry. The enzymatic hydrolysis of starch is a key step in the production of glucose syrup.
