Lactase in the food industry
The use of lactase has become widespread in the dairy and fermented beverage industries due to its ability to improve digestibility and maintain the sensory properties of the product. Its main applications include:
Traditional dairy products
Lactose-free milk, yogurt, and cheese, preserving natural flavor, texture, and color. Lactase allows for the production of products suitable for people with lactose intolerance without compromising quality.
Dairy desserts and ice creams
It facilitates digestion and provides natural sweetness, optimizing consistency, creaminess and sensory experience.
Fortified plant-based drinks
In formulas containing added lactose, lactase improves the flavor and texture profile, ensuring easier digestion and a balanced sweetness.
What is lactase and what is its function?
Lactase, also called β-galactosidase, is a hydrolytic enzyme that breaks down lactose into its simple sugars: glucose and galactose. It is obtained primarily from microbial sources and yeasts, and its action is essential for:
To produce lactose-free products without altering sensory properties.
To facilitate digestion in intolerant consumers.
Improve functionality and natural sweetness in dairy and fermented products.
Characteristics of lactase
Lactase has properties that make it especially versatile in the food industry:
High specificity for lactose
It prevents the hydrolysis of other sugars present.
Stability in the pH and temperature range of dairy products
It works optimally under conditions of milk and dairy product processing.
Improves digestibility and natural sweetness
By hydrolyzing lactose, the availability of simple sugars is increased and the flavor is improved.
Compatible with fermentations and other dairy enzymes
It can be integrated into combined enzymatic processes without affecting fermentation cultures.
Furthermore, lactase is a sustainable tool by reducing waste and optimizing production processes, aligning with trends in energy efficiency and functional foods.
