Catalase supplied by Huilin
Catalase (EC 1.1.1.6) is a ubiquitous antioxidant enzyme found in nearly all aerobic organisms. Its primary function is to rapidly decompose hydrogen peroxide (H₂O₂) into water and molecular oxygen-one of the fastest enzymatic reactions known.
Commercially, catalase is produced mainly through microbial fermentation (using Aspergillus niger, Bacillus subtilis, or Streptomyces griseus). Microbial fermentation is now the dominant method due to its scalability, batch‑to‑batch consistency, and animal‑free, BSE/TSE‑free production.

Manufacturing Process
Our catalase powder is produced via submerged microbial fermentation (GRAS‑certified strain). The crude enzyme is separated, concentrated, purified, formulated, and then spray‑dried or vacuum‑dried to a fine powder. Finished powder is sieved, tested for activity and purity, and packaged in moisture‑barrier containers under temperature‑controlled conditions.
catalase function
1. Potent Antioxidant & Cellular Protector
Catalase rapidly breaks down H₂O₂, preventing oxidative damage to proteins, lipids, and DNA. A 12‑week double‑blind, placebo‑controlled trial demonstrated that catalase activity can be significantly augmented in healthy adults through nutritional intervention [1].
2. Supports Healthy Aging
Increased plasma catalase concentrations have been highlighted as a potential anti‑aging effect in healthy populations [1].
3. Promotes Animal Growth & Welfare
A 2020 animal study found that dietary catalase supplementation improved growth performance, increased antioxidant enzyme activity, and reduced liver oxidative stress and hepatic apoptosis in weaned piglets [2].
4. Improves Recovery & Reduces Oxidative Stress
By neutralizing reactive oxygen species (ROS), catalase helps the body recover from metabolic stress. Increased catalase activity correlates with reduced plasma malondialdehyde levels-a key marker of oxidative damage [2].

Applications of the catalase enzyme
1. Food & Beverage Processing
Removes residual H₂O₂ from milk (cheese production) and aseptic packaging sterilants.
2. Cosmetics & Personal Care
Formulated into skincare serums, face masks, and haircare products for oxidative protection.
3. Animal Nutrition & Pet Food
Feed‑grade catalase supports antioxidant defense and growth performance in livestock [2].
4. Textile & Pulp/Paper Industry
Removes H₂O₂ after fabric bleaching, reducing water and energy consumption.
5. Pharmaceuticals & Research Reagents
Used in oxidative stress studies, cell culture media, and diagnostic assays [3].
6. Industrial Wastewater Treatment
Treats H₂O₂‑containing effluents, reducing environmental toxicity.
Frequently Asked Questions (FAQ)
Q: What is the difference between catalase from microbial fermentation and bovine liver extraction?
A: Microbial fermentation (using Aspergillus niger) is the preferred method. It offers superior batch consistency, is BSE/TSE‑free, and avoids animal sourcing concerns. All our catalase is microbial.
Q: What are the critical quality control parameters for catalase powder?
A: Key parameters: enzyme activity (U/g or U/mg), loss on drying (<8.0%), heavy metals (total ≤10 ppm), microbiological limits, and unit definition consistency. COA provided.
Q: How should catalase powder be stored, and what is its shelf life?
A: Store tightly sealed, protected from light and moisture, at 2–8°C (refrigerated). Shelf life: 24 months.
Q: What is the optimal pH and temperature range for catalase activity?
A: Active at pH 5.0–8.0 (optimal ~7.0). Temperature range 20–50°C (optimal 25–40°C). Inhibited by heavy metal ions (silver, mercury, copper, cyanide).
Q: What is the difference between food/industrial grade and high‑purity research grade catalase?
A: Food grade: ≥50,000 U/g powder for bulk industrial use. Research grade: ≥2,000–5,000 U/mg protein for diagnostics and cell culture.
Q: Why does the CAS number sometimes appear as 81457-95-6?
A: 9001-05-2 is the broad CAS for catalase. 81457-95-6 is specific to bovine liver catalase (21 CFR 184.1034). Our microbial catalase uses 9001-05-2.
Q: What packaging options are available?
A: Aluminum foil bags (1–5 kg), sealed HDPE drums (10–25 kg), fiber drums (25–50 kg), and custom packaging.
Q: Why are animal‑free (microbial) catalase products preferred in 2026?
A: Due to BSE/TSE concerns and animal‑free processing requirements for vegan certification and international trade, microbial catalase is now preferred over bovine‑derived catalase.
