Project Description
Product Description
Lactase is a digestive enzyme that breaks down lactose, the sugar found in milk and dairy products, into easily absorbable glucose and galactose. This enzyme is essential for individuals with lactose intolerance, as it helps prevent digestive discomfort such as bloating, gas, and diarrhea. Available in various forms including capsules, tablets, and drops, lactase supplements can be taken with dairy-containing meals to improve digestion and nutrient absorption. Highly effective and fast-acting, lactase enables lactose-intolerant individuals to enjoy dairy without adverse effects while supporting gut health and overall digestive wellness.
Core Functional Benefits
-
Eliminate Lactose Intolerance Symptoms: Hydrolyzes undigested lactose to prevent post-dairy bloating, gas, cramping, and diarrhea for sensitive consumers
-
Improve Dairy Taste & Texture: Generated glucose enhances natural sweetness, reducing additional sugar dosage; improves creaminess of ice cream and fermented yogurt
-
Boost Nutrient Bioavailability: Converts indigestible disaccharide into absorbable monosaccharides, promoting calcium, protein and vitamin uptake
-
Strain-Specific Stability: Acid-resistant fungal version survives gastric environment; heat-resistant bacterial version adapts high-temperature food processing
-
Clean-Label Friendly: Microbial fermented, no chemical hydrolysis, compliant with global clean label and natural ingredient trends
Core Classification & Source Differentiation
The source of lactase determines its working environment, stability, and applicable scenarios. We provide three mainstream industrial strains with clear application positioning for your formula selection.
Yeast-Derived Lactase (Kluyveromyces lactis)
- Biochemical Characteristics: Neutral pH optimum (pH 6.0–7.0), optimal temperature 35–40°C; active under dairy natural pH conditions
- Core Advantages: Excellent solubility in raw milk; mild reaction, no bitter byproducts; high hydrolysis rate for liquid dairy
- Best For: Industrial production of lactose-free liquid milk, UHT milk, fresh yogurt, and pasteurized dairy beverages
- Application Case: Continuous inline hydrolysis for 200,000L/day low-lactose milk production, achieving 95%+ lactose degradation without changing original milk flavor
Fungal-Derived Lactase (Aspergillus oryzae / Aspergillus niger)
- Biochemical Characteristics: Acidic pH optimum (pH 4.5–5.5), high temperature tolerance (50–60°C); strong acid resistance
- Core Advantages: Resists gastric acid degradation, maintains high activity in the stomach; high thermal stability for post-processing; ideal for whey hydrolysis
- Best For: Oral digestive supplements, acidic fermented dairy, whey upgrading, high-temperature processed dairy foods
- Application Case: Added to enteric-coated lactase tablets, remaining 85% active after passing through gastric juice, ensuring targeted small-intestine digestion effect
Bacterial-Derived Lactase
- Biochemical Characteristics: Broad pH adaptation range, ultra-high thermal stability, low-cost large-scale fermentation
- Core Advantages: Cost-effective; stable during high-temperature baking and extrusion processing; suitable for complex solid matrix
- Best For: Dairy-based baked goods, meal replacement powder, extruded nutritional bars, bulk industrial whey processing
- Application Case: Incorporated into high-protein baked bars, retaining 70% enzyme activity after 180°C baking, eliminating lactose-induced flatulence in finished products
Industry Application & Verified Cases (By Source)
Lactose-Free Dairy Manufacturing (Core Track: Yeast Lactase)
Yeast-derived lactase matches the natural neutral pH of raw milk, the mainstream choice for commercial low-lactose dairy lines.
- Applicable Products: UHT lactose-free milk, pasteurized fresh milk, drinking yogurt, plant-dairy blended beverages, infant formula
- Process Advantage: Low-temperature inline hydrolysis, no damage to milk protein; maintains original flavor and nutritional value
- Verified Case: Cooperated with a European dairy factory, using K. lactis lactase for continuous hydrolysis; final product lactose content ≤0.1g/100mL, fully meeting EU lactose-free labeling standards
Digestive Health Dietary Supplements (High-Margin Track: Fungal Lactase)
Acid-resistant fungal lactase is the gold standard for oral supplements, solving the failure of neutral lactase deactivated by stomach acid.
- Applicable Dosage Forms: Immediate-release tablets, chewable tablets, enteric-coated capsules, oral drops, digestive enzyme complex powders
- Formulation Advantage: Stable at gastric pH 2.0–3.0, delivers high activity to the small intestine; compatible with protease, amylase and probiotics
- Verified Case: A US nutraceutical brand adopted our A. oryzae lactase for chewable tablets; in-vivo test shows 82% enzyme retention after gastric transit, significantly improving consumer dairy tolerance feedback
Processed Food & Industrial Whey Utilization (Cost-Effective Track: Bacterial & Fungal)
- Applicable Products: Dairy protein bars, baked pastries, meal replacement powders, whey protein isolates, frozen desserts
- Process Advantage: High thermal stability tolerates extrusion and baking; fungal lactase improves whey hydrolysis efficiency for byproduct upgrading
- Verified Case: Used in high-protein baked snacks, retains 70% activity after 185°C short-time baking, eliminating lactose-induced digestive discomfort in fitness population
