Lactase Enzyme FAQ For Buyers: Specifications, Applications, And How To Choose A Reliable Supplier

(MENAFN- GetNews) Xi'an, Shaanxi, China – September 7, 2026 – Driven by the growing market for lactose-free food, lactase, as a key functional enzyme raw material, is widely used in dairy products, nutritional supplements and food processing.

For procurement professionals, selecting the right lactase enzyme requires more than just checking enzyme activity. Factors including enzyme type, stability, intended-use applications and supplier qualifications should also be taken into account. This FAQ guide covers key points buyers need to consider before purchasing lactase.

1 Is Lactase Enzyme?

Lactase enzyme, also known as β-galactosidase, is an enzyme that hydrolyzes lactose into glucose and galactose is commonly used to produce lactose-free or low-lactose dairy products and improve digestibility is widely used in dietary supplements, functional foods, and dairy products.

Q1 What Is Lactase Enzyme Used For?

Lactase helps facilitate lactose digestion and improves dairy product tolerance. It is widely applied in the following fields:

Lactose-free milk production /Dairy beverages /Yogurt processing /Whey ingredient processing /Nutritional supplements

Q2 What Specifications of Lactase Enzyme Do You Supply?

Lactase enzyme is available in different activity levels based on application requirements. Please refer to the specification table below for details.

Product	Character	Activity	Remarks
Acid Lactase(β-galactosidase)	Powder	100000 ALU/g	It can be used as digestive aid in the dietary supplements. It also can be applied to process free-lactose yogurt.
Powder	150000 ALU/g
Powder	160000 ALU/g
Liquid	20000 ALU/g

We also offer custom enzyme activity specifications upon customer request.

Q3 What Is the Difference Between Neutral Lactase and Acid Lactase?

Neutral lactase is commonly used in milk and dairy processing under neutral pH conditions.

Acid lactase is mainly applied in acidic environments, such as yogurt and fermented dairy products.

Choosing the right type depends on: processing temperature /pH condition/application requirements

Q4 How Do I Choose the Right Lactase Enzyme?

1. Application

Lactase performance requirements differ greatly for various end applications. Lactase used in dairy processing, lactose free food and dietary supplements shows clear distinctions in temperature resistance and pH tolerance. Proper selection matches diverse formulations including lactose free milk, yogurt, milk powder, lactase tablets and capsules, delivering stable lactose hydrolysis and consistent finished product quality.

2 Activity

Enzyme activity serves as the core performance indicator for lactase. High-activity lactase features superior hydrolysis efficiency, reduced production cycle and lower total dosage, which helps save production costs. Our best selling specifications are 100000 ALU/g-160000 ALU/g, ideal for both low dose dietary supplement formulas and large scale industrial grade dairy manufacturing.

3

Lactase retains good activity at 40-55 °C. Activity drops sharply when continuously heated above 60 °C. For dairy processing, keep reaction temperature at 45-50 °C for optimal hydrolysis.

Its optimal stable pH range is 4.0-4.5. Activity decreases under strongly acidic (pH < 3.5) or strongly alkaline (pH > 8.0) conditions. Keep your formulation within this pH range to preserve lactase activity.

4

Reliable lactase suppliers supply full compliance documents for global food grade customs clearance, product registration and quality inspection, such as COA, MSDS, specification sheet, heavy metal and microbial test reports for food applications.

Q5 What Factors Affect Lactase Enzyme Activity?

Lactase activity is mainly affected by temperature, pH value, humidity and storage environment. High temperature over 60°C causes fast deactivation. Strong acid or strong alkaline conditions reduce catalytic performance. Humidity, air exposure and sunlight will also degrade activity. Do not add lactase before high-heat processing steps.

Q7 Do You Provide Lactase Enzyme Samples?

Yes, free 10-20g samples are available for production testing and evaluation.

Q8What Is the MOQ for Lactase Enzyme?

MOQ depends on packaging requirements and order quantity.

Standard packaging is usually 20kg/drum trial orders or samples can be discussed according to customer requirements.

Q9 How Should Lactase Enzyme Be Stored?

Lactase enzyme should be stored in a cool, dry place away from direct sunlight and moisture storage helps maintain enzyme activity during shelf life.

Q 10Why Choose a Reliable Lactase Enzyme Supplier?

Choosing the right Lactase Enzyme supplier is essential for product quality and production efficiency.

When selecting a lactase enzyme supplier, buyers should evaluate:
