enzymatic hydrolysis of starch
How do enzymes affect starch?
Starches treated with enzymes result in their modifications owing to de-branching action, phosphate substitution, and disproportionation by altering the starch chain length and branch point formation ( Park et al., 2008 ). This green technique imparts unique characteristics to the starch which have been discussed in the following paragraph.
What happens if starch hydrolysis is complete?
This process is called hydrolysis, and if it is complete, it will give only glucose. However, this is not what happens in practice. Starch hydrolysis can be accomplished essentially by physical (heat), chemical (with organic or inorganic acids), and enzymatic processes.
What are the enzymatic conversion products of starch?
The enzymatic conversion products of starch vary in chain size, starting from glucose (1 molecule) reaching carbon residues of 5–11 glucoses, characterizing the dextrins, of higher molecular weight.
Which enzyme is used for starch hydrolysis?
1. Introduction Enzymes are used for starch hydrolysis (amylase or amylolytic enzymes) have attracted great attention because of biotechnological approaches and economic benefits. There are several types of amylases and the most commonly used in the industry include α -amylases, β -amylases, and glycoamylases , .
