acid and enzyme hydrolysis of starch

What is the effect of acid hydrolysis on starch?
Acid hydrolysis decreased the starch molecular size to a stable value.
Acid disrupted the waxy starch lamellar structure effectively.
Two different degradation pattern were observed in starch granules.
Thermal decomposition temperature of acid-hydrolyzed starch became lower.
What are the enzymes used in 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 [1], [2].
Acids such as hydrochloric and sulfuric hydrolyze glycoside linkages and modify starch properties such as viscosity and solubility, and thus have been widely used in the starch industry to improve food texture, as well as in the paper industry.

What happens when acid reacts with starch?

Acid modification is an example of such modification its use may alter the properties of the starch.
The reaction between the acid and the starch, in general, alters the morphology of the granule and degrades the starch chains to fragments of lower molecular weight [14].

In order to produce bioethanol, starch hydrolysis could be done by both acid hydrolysis as well as enzymatic hydrolysis. Starchy substrate are hydrolyzed into sugars by α-amylase and glucoamylases. Alternatively, dilute acid such as HCl and H

During acid hydrolysis, amylopectin chains, the branches that diverge from the main amylose chain, are broken from the amylose chain Enzymatic hydrolysis of the starch however, does not break apart the amylose chains into monomers of glucose because it is specific and targets only the alpha 1, 6 glycosidic bond
