EXPERIMENT 5-HYDROLYSIS OF STARCH BY ?-AMYLASE Starch is mainly composed of two parts: - Amylose: a linear polymer made up of ?-1-4 bound D-glucose units This polysaccharide is making up approximately 20-30 of the structure - Amylopectin: a polysaccharide with highly branced polymer of ?-1-6 bound glucose units

What is starch hydrolysis?

Starchhydrolysis is an important process to hydrolyze starchinto glucose, which can be further converted to highfructose syrup for various applications in the foodindustry. Starch hydrolysis consists of two steps: gela-tinization and sacchari?cation.

How do you Mix starch and sulfuric acid?

Place 5.0 mL of starch solution in a 150 x 15 – mm test tube and add 1.0 mL of dilute sulfuric acid (3 M H2SO4). Mix it by gently shaking the test tube. Heat the solution in a boiling water bath for about 5 min.

Can modified inner cylinder be used for starchhydrolysis?

As aresult, mixing gelatinized starch with the enzyme mightbe further improved using the modi?ed inner cylinder.Performance of the modi?ed inner cylinder for starchhydrolysis will be experimentally investigated in thefuture. In Taylor vortex?ow region, starch slurry washydrolyzed continuously and more ef?ciently.

What is the hydrolysis of sucrose and amylose?

The hydrolysis of sucrose or amylose can be achieved by using a strong acid such as HCl or with the aid of biological catalysts (i.e., enzymes). Starch can form an intense, brilliant, dark blue or violet colored complex with iodine.
