Alpha Amylase
What is the role of alpha amylase?
The core role of α-amylase is to hydrolyze carbohydrates such as starch and glycogen, generating small molecules like maltose and dextrin. It is present in human and animal saliva and pancreatic juice to aid digestion and is also widely used in food processing, brewing, detergents and other industrial fields.

Mechanism of action:
Alpha-amylase efficiently hydrolyzes soluble starch, amylose, glycogen, and other polysaccharides by randomly cleaving the α-1,4-glucosidic bonds within the sugar chain. This process breaks down starch and glycogen into dextrins, oligosaccharides, and monosaccharides of varying chain lengths, leading to a rapid decrease in the viscosity of the solution.

Food Industry
Alpha-amylase is widely used in food production, especially in bread, cookies, and cakes. It helps break down starch, improving dough fermentation properties and enhancing texture.
Sugar Production
In sugar production, α-amylase is used to hydrolyze starch into glucose and maltose, commonly employed in the production of high-fructose corn syrup (HFCS) and other sweeteners.
Brewing Industry
In beer and other alcoholic beverage production, α-amylase is used to convert starches in grains into fermentable sugars, improving fermentation efficiency and alcohol yield.
Animal Feed
In animal feed production, α-amylase helps break down starch in feed, improving digestibility and promoting healthy growth in livestock.
Solubility: Easily soluble in water, forming a clear, light yellow aqueous solution. Insoluble in ethanol or ether.
Efficient Starch Hydrolysis: Alpha-amylase rapidly breaks down starch and glycogen, reducing solution viscosity and converting them into dextrins and oligosaccharides, widely used in food processing, fermentation, and other industries.
Thermal Stability: Alpha-amylase maintains stability within the temperature range of 30-85°C. Its enzymatic activity is optimal between 65-75°C, ensuring efficient starch hydrolysis in various industrial applications.
What does it mean when alpha amylase is high?
An increase in α-amylase usually indicates problems in the pancreas, salivary glands or kidneys. It is commonly seen in acute pancreatitis, chronic pancreatitis, salivary gland inflammation, renal insufficiency or gastrointestinal diseases. Further diagnosis requires combining other clinical symptoms and test results.
What is alpha amylase medicine used for?
The α-amylase medicine is used to promote the breakdown of starch and glycogen, helping to improve digestive function, especially in cases where pancreatic function is insufficient or there is digestive disorder. It can be used to treat digestive disorders, aiding in the digestion and absorption of food.
What foods contain alpha-amylase?
The foods containing α-amylase mainly include:
Foods rich in starch: such as potatoes, rice, wheat, corn, etc. The starch in these foods is broken down by α-amylase during digestion.
Fermented foods: such as bread, beer, etc. During fermentation, α-amylase helps convert starch into sugar.
