Lactase Enzyme Powder

Lactose intolerance affects millions of people worldwide. Lactase enzyme offers a practical solution within dairy manufacturing itself. So, how does this enzyme actually help?

This guide explores its function and applications across the dairy industry.

What Is Lactase?

Lactase, like LEAFLACT, is a beta-galactosidase enzyme obtained through controlled fermentation of Aspergillus species. This enzyme breaks down lactose, the sugar found in milk and dairy products.

Specifically, lactase splits lactose into two simpler sugars: glucose and galactose. As a result, the final product becomes easier to digest.

Why Lactase Matters in Dairy Processing

Many people lack sufficient natural lactase in their digestive systems. Therefore, they experience discomfort after consuming regular dairy products.

By pre-treating milk with lactase, manufacturers create lactose-free or low-lactose products. Consequently, these products become accessible to a much wider consumer base.

Key Applications of Lactase Enzyme Powder

1. Lactose-Free Dairy Products

Lactase enables production of lactose-free milk, yogurt, and cheese. As a result, lactose-intolerant consumers can enjoy dairy without discomfort.

2. Whey Processing

This enzyme also improves whey product functionality. Because lactose crystallisation can cause texture issues, lactase treatment helps prevent that problem.

3. Flavour Enhancement

Since glucose and galactose taste sweeter than lactose, lactase treatment can also boost natural sweetness. Therefore, some manufacturers reduce added sugar as a result.

Product Specifications

Leaf CleanTech's LEAFLACT comes as a food-grade powder. It packs in 1 kg or 25 kg sizes, with a shelf life of 1 year under cool, dry storage.

Its efficiency rating reaches 50,000 ALu/g, with 99% purity for consistent dairy processing results.

How to Apply Lactase in Dairy Production

First, determine the lactose content of your milk source. Then, calculate dosage based on your target lactose reduction percentage.

Next, apply the enzyme during the appropriate processing stage, typically before or during pasteurisation. Finally, test the finished product to confirm lactose levels meet your labelling requirements.
