Where is the application field of lactase?

Dairy industry:
Production of low-lactose or lactose-free dairy products: It can hydrolyze lactose in milk, etc., prepare low-lactose milk, and solve the problem of lactose intolerance;
Production of oligosaccharides: Using its transglycosylation activity to produce oligosaccharides can adjust the stomach and intestines, promote the production of bifidobacteria in the intestines, maintain the balance of intestinal microecology, and has stable properties and is not easily absorbed by the small intestine. It can replace other sugars and be added to low-sugar foods for people with hyperlipidemia, obesity, and diabetes;
Improved dairy products: Adding to concentrated or frozen dairy products can prevent lactose crystallization , improve the sweetness of the product, reduce the amount of sucrose, reduce the freezing point of galactose generated by hydrolysis, and improve the melting resistance of frozen dairy products; it can also shorten the fermentation cycle of yogurt, reduce the amount of sucrose and improve the taste of the product;
Alternative sugar additives: whey syrup produced by adding lactase to whey has a taste similar to the sweetness of sucrose, and its solubility is several times higher than that of lactose. It can be used as a sucrose substitute for various food processing, and can also be used to make milk soft candy, etc., to avoid the appearance of texture, sand bags, lactose crystallization and caramelization;
Produce low-lactose ice cream and other products.
Medical field: It can be used to treat lactose intolerance. For people who lack lactase, supplementing lactase can help decompose lactose and relieve symptoms such as abdominal distension, abdominal pain, and diarrhea caused by lactose digestion and absorption disorders.
Fruit and vegetable processing: Lactase in plants can decompose galactoside in cell wall polysaccharides to produce galactose, which can soften fruits and accelerate the ripening of fruits and vegetables. It has been widely used in softening a variety of fruits and promoting the ripening of vegetables.
Lactase is a safe biological enzyme preparation. With the development of related technologies, its application scope may be further expanded. However, in specific applications, relevant regulations and standards must be strictly followed to ensure the safety and effectiveness of use. At the same time, lactase from different sources may have different characteristics, and it is necessary to choose according to specific needs and conditions when using it. If an individual considers using lactase-related products due to lactose intolerance, it is recommended to do so under the guidance of a professional.
