Lactase, also known as β-galactosidase, is derived from Aspergillus oryzae. It is a food-grade enzyme produced through submerged fermentation. Lactase hydrolyzes lactose into glucose and galactose, thereby improving the digestibility of dairy products and enhancing nutrient absorption.
Lactase is available in both powder and liquid forms with different enzyme activity levels. The powder specifications range from 50,000 ALU/g to 160,000 ALU/g, while the liquid form is available at 20,000 ALU/g, allowing flexible application in various production processes.Lactase with enzyme activity above 100,000 ALU/g features high concentration and good stability, making it widely suitable for enzyme-based dietary supplements such as capsules, tablets, and drops.

Enzyme activity definition: One lactase unit is defined as the quantity of enzyme that will liberate o-nitrophenol at a rate of 1µmol per minute under the condition of hydrolyze oNPG at 37ºC and pH4.5.
Stability Data
Function/Application
The Lactase from Aspergillus oryzae has a high activity at low pH(pH3.5~5.5), making it particularly suitable for digest lactose in acid conditions, and it's therefore ideal for use in the dietary supplements as digestive aid.
The dose of fungal lactase depends on the amount of the lactose and the size of meal consumed, one general guideline is 2,500ALU per 10~13g of lactose consumed. We recommend a dose of 4,000~6,000ALU with each lactose-containing meal.
Application
1. Food Processing
Used in dairy products such as milk, yogurt, cheese, and milk powder to produce low-lactose products, improve taste, and meet the needs of lactose-intolerant consumers. Also applied in food improvement and GOS (prebiotic) production for functional foods.
2. Health & Pharmaceutical
Used as a dietary supplement to compensate for insufficient lactase activity in the human intestine. It helps relieve symptoms of lactose intolerance such as bloating and diarrhea, and is suitable for various groups including pregnant women, breastfeeding women, and infants.
3. Industrial Use
Used in large-scale dairy processing to improve efficiency, reduce waste, and lower production costs.
