Lactase NZs-BE-B012

Catalog Number NZs-BE-B012

Grade Food Grade

Category Amylases

Description

Lactase NZs-BE-B012 is a high-quality lactase enzyme powder designed for the hydrolysis of lactose into glucose and galactose. It works by breaking the β-galactosidic bonds in lactose, effectively reducing lactose content while enhancing sweetness naturally. This enzyme is widely used in the food and beverage industry to produce lactose-free or reduced-lactose products, improving digestibility and expanding product accessibility for consumers with lactose intolerance.

Applications

In the processing of low-lactose milk and milk powder, the enzyme effectively hydrolyzes lactose, helping to improve digestibility while also enhancing flavor, natural sweetness, taste, and nutritional value.
For yogurt production, it can help shorten coagulation time, support fermentation efficiency, reduce the need for added sugar, and improve the final flavor profile and overall sensory quality.
For ice cream, lactase contributes to improved texture, smoother consistency, and better structural stability, while also enhancing sweetness naturally.
In bread and bakery products, the enzyme may promote yeast fermentation, improve crust color and overall appearance, enhance sweetness, and potentially reduce the need for additional sugar, thereby supporting both product quality and formulation optimization.

Recommended Dosage

For fresh milk, the recommended dosage is 0.02-0.1% (v/v), while for milk powder, the typical usage level is 0.2-0.4% (on a dry weight basis). The exact application rate should be carefully optimized according to the specific production requirements, raw material characteristics, and target product specifications, and processing conditions such as temperature, pH, and reaction time. Because performance may vary across different systems, it is advisable to conduct preliminary trials using a convenient and manageable dosage within the recommended range.

Storage

The product should be kept tightly sealed in its original packaging and stored in a dry, cool environment to maintain optimal stability and enzymatic activity. Avoid exposure to direct sunlight, high temperatures, humidity, and moisture, as these conditions may reduce product performance over time. After each use, ensure the container is properly closed to prevent contamination and protect the enzyme from environmental influences.
