Amylases are a group of enzymes that catalyze the hydrolysis of starch, resulting in the production of simpler sugars such as glucose and maltose. These enzymes have a wide range of applications in various industries due to their ability to break down complex carbohydrates into smaller, more useful molecules.

Food Industry:

Amylases find extensive application in the food industry for their ability to modify the texture and flavor of food products. The most commonly used amylases in this industry include alpha-amylase, beta-amylase, and glucoamylase.

- Alpha-amylase is used for the production of syrups, dextrins, and maltodextrins from starch. It breaks down the long chains of starch molecules into shorter chains of glucose and maltose, which can be easily used by the body.

- Beta-amylase is used in the brewing industry for the production of beer. It acts on the short chains of glucose and maltose produced by alpha-amylase and converts them further into maltose, which gives beer its characteristic taste.

- Glucoamylase is used to produce high fructose corn syrup (HFCS) from corn starch. It breaks down the starch into glucose, which is then isomerized to fructose using another enzyme called glucose isomerase.

Starch Sugar Industry:

The starch sugar industry uses amylases to convert starch into various forms of sweeteners such as glucose, maltose, and fructose.

- Alpha-amylase is used to break down the starch into shorter chains of glucose and maltose, which are then converted into glucose using glucose isomerase.

- Glucoamylase is used to convert the remaining longer chains of starch into glucose, which is then purified and crystallized into different forms of sugar.

Alcohol and Bioethanol Industry:

The alcohol and bioethanol industry use amylases to convert starch into simple sugars such as glucose, which are then fermented into ethanol.

- Alpha-amylase is used to break down the starch into shorter chains of glucose and maltose, which are then converted into glucose using glucose isomerase.

- Glucoamylase is used to convert the remaining longer chains of starch into glucose, which is then fermented by yeasts to produce ethanol.

Fermentation Industry:

Amylases play a crucial role in the fermentation industry by breaking down complex carbohydrates into simpler sugars that can be easily fermented by microorganisms.

- Alpha-amylase and glucoamylase are used to break down the starch present in grains and fruits into glucose, which is then fermented by yeast or bacteria to produce various alcoholic beverages and fermented foods.

Baking Industry:

In the baking industry, amylases are used to improve the quality of baked goods such as bread, cakes, and cookies.

- Alpha-amylase is used to break down the starch in flour into shorter chains of glucose and maltose, which help to soften the dough and improve its texture.

- Glucoamylase is used to convert the remaining longer chains of starch into glucose, which provides food for the yeast and helps to increase the volume and texture of the baked goods.

JuiceIndustry:

In the juice industry, amylases are used to break down starch present in fruits and vegetables, thereby increasing the yield of juice and improving its clarity.

Feed Industry:

The feed industry uses amylases to improve the digestibility and nutritional value of animal feed.

- Alpha-amylase and glucoamylase are added to animal feed to break down the complex carbohydrates present in grains and cereals into simpler sugars, which can be easily digested by animals.

Detergent Industry:

Amylases are used in the detergent industry to remove stains from clothes.

- Alpha-amylase is used to break down the starch present in food stains, while pullulanase is used to break down the polysaccharides present in blood and other protein-based stains.

Textile Industry:

Amylases find application in the textile industry for their ability to modify the viscosity of starch-based sizes during sizing and desizing for more efficient operation.

In conclusion, amylases have a wide range of applications in various industries due to their ability to break down complex carbohydrates into simpler sugars. The specific enzyme used depends on the desired end product and the particular application.

Sunson developed quite some amylase products according to address various concerns in different industries and are therefore very popular among big numbers of customers.
