1.Acid Lactase (β-galactosidase): Unlocking Dairy for Everyone
Acid Lactase, also known as β-Galactosidase, is an enzyme belonging to the glycosidase family. It can catalyze the decomposition of lactose into glucose and galactose, thereby helping to reduce the lactose content in food. This enzyme has high activity under relatively acidic conditions (usually with a pH value of 3.5 to 5), and thus is called acid lactase, which is different from neutral lactase.
β -galactosidase is not only present in animals (such as mammals), but also widely distributed in plants, microorganisms (such as bacteria and fungi), as well as certain prokaryotes and eukaryotes. This enzyme is usually encoded by the gene lacZ.

Used widely in dairy processing, it enables the creation of lactose-free milk, yogurt, and cheeses. Beyond food, it’s vital in pharmaceuticals to prevent lactose crystallization in medications.
2.Nattokinase: Nature’s Answer to Cardiovascular Wellness
Nattokinase is a serine proteolytic enzyme derived from natto, which was first isolated from the traditional fermented food natto by Japanese scientists in 1980. natto is made by fermenting soybeans with Bacillus subtilis natto, and nattokinase is secreted and produced by Bacillus subtilis natto during the fermentation process.
Nattokinase has been widely studied and applied due to its unique anticoagulant and thrombolytic properties. It is a protease with high safety and strong oral activity, and has attracted attention due to its potential to regulate cardiovascular health.

Nattokinase supplements are gaining traction for supporting heart health, improving circulation, and reducing hypertension risks. Researchers also explore its potential in anti-aging therapies and stroke prevention.
3.Dextranase (α-glucanase): The Sugar Industry’s Clean-Up Crew
Dextranase (also known as α -glucanase) is an enzyme that can specifically hydrolyze the macromolecular chains of Dextran. Dextrose is a polysaccharide formed by the connection of glucose through α-(1,6) -glycosidic bonds and is commonly found as a biological metabolite of certain microorganisms, such as bacteria. Dextran enzymes break down dextran into oligosaccharides or glucose by cleavage the α-(1,6) -glycosidic bond and belong to an important category of glycoside hydrolases.
Dextran is produced in microorganisms such as fungi and bacteria, and the enzymes isolated from it are widely used in fields such as food, medicine, and industrial processing.

This enzyme hydrolyzes dextran, a sticky polysaccharide that plagues sugar production by clogging machinery and reducing yield. Dextranase ensures efficient sugar refining, particularly in post-harvest sugarcane processing. It’s also used in dental care products to break down plaque biofilm and in biotechnology for polysaccharide analysis.
4.Invertase (Saccharase): Sweetening the Confectionery World
Invertase (also known as Saccharase) is a naturally occurring glycoside hydrolase, whose main function is to catalyze the decomposition of sucrose into glucose and fructose. This enzyme belongs to the glycoside hydrolase family and can specifically hydrolyze the **α-(1,2) -glycosidic bond ** in sucrose. Invertase is widely present in plants, animals and microorganisms (such as yeast, fungi and bacteria), and is an important enzyme in the sugar metabolism process of organisms.
Invertase has attracted much attention due to its function of catalyzing the conversion of sucrose into more absorbable and sweeter glucose and fructose, and is widely used in the food industry and biotechnology.

Invertase catalyzes the hydrolysis of sucrose into glucose and fructose, creating “invert syrup” prized for its smooth texture and moisture retention. Essential in candy manufacturing, it gives chocolate-covered cherries their liquid centers and keeps baked goods soft. The enzyme also aids in biofuel production by converting waste sugars into fermentable substrates.
