What is Glucoamylase?
Glucoamylase (EC 3.2.1.3) is an exo-acting enzyme that hydrolyzes 𝛼
-1,4 and 𝛼-1,6 glucosidic linkages from the non-reducing ends of starch and related polysaccharides, releasing glucose. Widely used in the starch processing and brewing industries, it converts maltodextrins into glucose, with optimal activity around 60∘C. It is primarily produced from fungi like Aspergillus and Rhizopus.
Everything You Need to Know
What is the function of the glucoamylase?
Glucoamylase is an enzyme of the glycoside hydrolase family. This enzyme is involved in digestion and is released in the cells of the small intestine. It breaks the bonds between two glucoses contained in polymers such as starch. Its particularity is to hydrolyse the residues from the ends of the molecule.

The Health Benefits of Glucoamylase
Glucoamylase is one of several digestive enzymes that can break down these starches into glucose, which is usable by the body. This encourages smooth digestion and may help deter common digestive upsets such as heaviness, lethargy, bloating, gas and loose stools.
What is the difference between amylase and glucoamylase?
As the alpha amylase breaks up the long starch chains into many smaller chains, it creates many new ends. Glucoamylase only works from the ends. When alpha amylase has done its job, glucoamylase can form glucose in the cook. That is what the yeast will eventually ferment.
What foods have glucoamylase?
Glucoamylase is an enzyme that digests partially processed starch (carbohydrates) in vegetables, potatoes, wheat, rice, and corn in order to release glucose that the body can use for energy.

Function: It breaks down starch into dextrose (glucose). It works by starting at the non-reducing end of the starch chain and releasing 𝛽
-glucose.
Industrial Applications:
Ethanol & Brewing: Crucial for breaking down long-chain dextrins into fermentable sugars, increasing yield.
Food Industry: Used in producing high-glucose and high-fructose syrups.
Baking: Helps in dough fermentation.
