Food Grade Lactase (β-Galactosidase) for Dairy Lactose Hydrolysis
Laktase Berkualitas Pangan, yang juga dikenal sebagai β-Galactosidase (β-D-galactosidase), is an enzyme that catalyzes the hydrolysis of lactose into glucose Dan galactose.
In addition to lactose hydrolysis, lactase may exhibit transgalactosylation activity under suitable processing conditions.
With optimal activity in a near-neutral pH range, this enzyme is highly suitable for milk and dairy processing, enabling efficient production of low-lactose Dan lactose-free products.
Hydrolysis of lactose improves digestibility for lactose-intolerant consumers and increases the natural sweetness of dairy products. As glucose and galactose are sweeter than lactose, lactase-treated dairy may help reduce
the need for added sugars while preserving the original flavor profile.
Fitur Utama
- High lactose hydrolysis efficiency: lactose conversion can exceed 99% under recommended conditions.
- Optimal performance at dairy-relevant pH: best activity observed between pH 6.0 and 7.0.
- Effective at moderate temperatures: well suited for standard dairy processing conditions.
- Peningkatan kualitas produk: reduces lactose-related crystallization and enhances sweetness perception.
- Wide applicability: compatible with liquid milk, fermented dairy products, milk powder solutions, and dairy-based foods.

Area Aplikasi
- Low-Lactose and Lactose-Free Dairy Products
Reduces lactose content in dairy products, supporting improved tolerance and broader consumer acceptance. - Fermented Dairy Products
Lactose hydrolysis prior to fermentation can help reduce quality issues associated with excessive lactose, including crystallization and texture defects. - Dairy Ingredients and Milk Powder Applications
Hydrolyzed lactose increases sweetness and digestibility, enabling reduced added sugar and improved nutritional perception. - Baked Goods and Dairy-Based Foods
The use of lactase-treated milk can help prevent undesirable aroma and color changes, support yeast fermentation, and improve final product volume and texture.
Typical Processing Guidelines
Liquid Milk
- Add lactase at 0.02 – 0.1% based on liquid weight.
- Hydrolyze at 35 °C for approximately 5 hours, or at low temperature (~9 °C) for 20–24 hours.
- Apply gentle agitation during hydrolysis to ensure uniform mixing.
- Heat to approximately 85 °C after hydrolysis if enzyme inactivation is required, then cool and continue with downstream processing.
Milk Powder Solution
- Prepare a milk powder solution at approximately 12% total solids.
- Add lactase at 0.2 – 0.4% based on dry matter.
- Proceed with hydrolysis using the same time and temperature conditions as liquid milk.
Relative Enzyme Activity
pH vs. Relative Activity
- Highest activity observed around pH 6.5 – 7.0.
- Activity decreases gradually at lower or higher pH values.
Temperature vs. Relative Activity
- Activity increases with temperature and reaches a maximum around 40 °C.
- Activity declines noticeably above 45 °C and at higher temperatures.
Penyimpanan
- Simpan di dalam cool, dry environment, protected from direct light.
- Suhu penyimpanan yang dianjurkan: di bawah 0 °C.
- Prolonged exposure to high temperature or humidity may reduce enzyme activity; dosage adjustments may be necessary if storage conditions are not optimal.
Keamanan dan Penanganan
Lactase is a protein-based enzyme used in food processing. Although generally safe, exposure to concentrated enzyme dust may cause sensitization in susceptible individuals.
- Avoid inhalation of enzyme dust; use appropriate respiratory protection.
- Gunakan sarung tangan pelindung dan pelindung mata saat menangani.
- Hindari kontak kulit atau mata yang berkepanjangan.
- This enzyme may be inhibited or degraded by certain metal ions (such as Fe3+, Cu2+, Hg+, and Pb2+) and by strong oxidizing agents; direct contact with these substances should be avoided.
