Product Description

Product Description
Lactase-1
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.
● Powder specifications range from 50,000 ALU/g to 160,000 ALU/g.
● 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 pH 4.5.
Function / Application
The Lactase from Aspergillus oryzae has a high activity at low pH (pH 3.5–5.5), making it particularly suitable for digesting lactose in acid conditions, and it is therefore ideal for use in dietary supplements as a digestive aid.
📑 The dose of fungal lactase depends on the amount of lactose and the size of meal consumed. One general guideline is 2,500 ALU per 10–13g of lactose consumed. We recommend a dose of 4,000–6,000 ALU with each lactose-containing meal.
🍔 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.

❓ Frequently Asked Questions (FAQ)
Q What is Lactase and where does it come from?
Lactase (β-galactosidase) is a food-grade enzyme derived from Aspergillus oryzae through submerged fermentation. It breaks down lactose into glucose and galactose, improving the digestibility of dairy products and enhancing nutrient absorption.
Q What forms and activity levels is Lactase available in?
Lactase is available in both powder and liquid forms. The powder ranges from 50,000 ALU/g to 160,000 ALU/g, while the liquid form is available at 20,000 ALU/g. High-activity versions (above 100,000 ALU/g) are suitable for dietary supplement formats such as capsules, tablets, and drops.
Q What is the recommended dosage of Lactase for lactose intolerance?
A general guideline is 2,500 ALU per 10–13g of lactose consumed. The recommended dose is 4,000–6,000 ALU with each lactose-containing meal. Actual dosage may vary depending on individual sensitivity and the amount of lactose ingested.
Q What are the main applications of Lactase?
Lactase has three primary application areas: (1) Food Processing — used in milk, yogurt, cheese, and milk powder to produce low-lactose dairy products and functional foods; (2) Health & Pharmaceutical — used as a dietary supplement to relieve lactose intolerance symptoms; (3) Industrial Use — applied in large-scale dairy processing to improve efficiency and reduce costs.
Q How is Lactase packaged and what are the storage options?
For 1 kg orders, Lactase is packed in a bag with a box outside (double plastic bag + aluminum foil bag inside). For 10 kg, 25 kg, or larger quantities, it is packed in drums or cartons with 2 layers of plastic bag inside to ensure product integrity during transport and storage.
Q What are the available shipping methods and delivery times?
For orders of 1–25 kgs, shipping is available via EMS, DHL, UPS, or FedEx with a delivery time of 3–7 days (door to door). For 25–100 kgs, DHL, FedEx, or Air freight is available in 3–7 days. For orders over 100 kgs, air freight takes 3–7 days (door to airport) and sea freight takes 10–35 days (door to port).
