GUBOND Lactase‑High Quality Digestive Enzyme

Lactase Enzyme for Milk Yogurt and Dairy Products

Overview

Lactase is a carbohydrate-hydrolyzing enzyme used to break down lactose into glucose and galactose. It is commonly applied to dairy processing and formulations where controlled lactose hydrolysis is required.

Commercial Lactase is mainly available as an enzyme powder, while liquid preparations are also used in food and beverage processing. Powder products typically range from off-white to light yellow-brown, while liquid grades range from light yellow to brown.

Typical application areas include dairy products, lactose-free foods, beverages, and dietary supplements. Commercial grades are generally standardized according to measured enzyme activity, with microbiological quality and heavy metal testing included in routine product evaluation.

Technical Specifications

Functional and Formulation Characteristics

Lactase catalyzes the hydrolysis of lactose into the monosaccharides glucose and galactose. This enzymatic activity makes it suitable for processing milk and other lactose-containing formulations.

Key characteristics include:

• Specifically applicable to lactose-containing substrates.
• Supports controlled enzymatic lactose hydrolysis.
• Available in powder and liquid preparations.
• Suitable for dairy and beverage processing systems.
• Applicable to dietary supplement formulations.
• Standardized according to enzyme activity.

The actual performance of Lactase depends on pH, temperature, lactose concentration, enzyme dosage, reaction time, and the composition of the processing matrix. Different commercial enzyme grades may have different operating profiles, so processing parameters should be confirmed according to the intended application.

Application Context

In dairy processing, Lactase can be used for enzymatic lactose hydrolysis in suitable milk-based products. The required enzyme dosage and treatment conditions depend on the product matrix and target processing parameters.

For lactose-free food formulations, Lactase can be incorporated during manufacturing to modify the lactose content of suitable dairy-derived ingredients.

In beverage processing, liquid or powder Lactase may be selected according to the production system, formulation composition, and processing conditions.

Lactase is also used as an enzyme ingredient in dietary supplement formulations. For these applications, product selection should consider enzyme activity, dosage form, stability, microbiological specifications, and compatibility with other formulation components.

Composition and Standardization

The principal functional component is active Lactase enzyme. Commercial preparations may contain suitable carriers or stabilizing ingredients depending on the powder or liquid product format.

Routine quality-control parameters include:

• Lactase enzyme activity.
• Physical appearance.
• Microbiological quality.
• Heavy metal testing.
• Batch consistency.

Enzyme activity is the primary parameter used for commercial standardization. When comparing Lactase grades, buyers should evaluate the declared activity together with the analytical method and activity-unit definition.

A batch-specific COA can provide relevant analytical results. Powder Lactase should be kept in sealed packaging under cool, dry conditions and protected from moisture, direct sunlight, and excessive heat.
