How Catalase Works

Catalase (EC 1.11.1.6) rapidly decomposes hydrogen peroxide into water and oxygen — one of the fastest enzymatic reactions known. A single catalase molecule can decompose over 200,000 H₂O₂ molecules per second.

Rapid H₂O₂ Decomposition

Catalase converts H₂O₂ → H₂O + ½O₂ with extreme speed (kcat >200,000 s⁻¹). Even trace peroxide residuals are eliminated within minutes at typical process temperatures.

Prevents Oxidative Damage

Residual hydrogen peroxide causes off-flavors in food and beverage products, inhibits fermentation yeast, and damages textile dyes. Catalase ensures complete removal before downstream processing.

Reduces Water Consumption

In textile processing, catalase eliminates residual bleaching peroxide in a single enzymatic step — replacing multiple water rinse cycles and reducing water consumption by 30–50%.

Catalase Applications by Industry

Catalase is used in any process where residual hydrogen peroxide must be removed quickly and completely.
Processamento de Laticínios

Removes residual H₂O₂ from cold-sterilized milk, cheese brine, and egg products after peroxide treatment, preventing oxidative off-flavors and ensuring food safety compliance.

Têxteis

Eliminates peroxide residuals after cotton bleaching in a single enzymatic step, replacing multiple water rinses. Reduces water use by up to 50% and cuts dye inconsistency caused by peroxide carry-over.

Brewing & Fermentation

Destroys residual H₂O₂ after equipment sterilization before inoculation. Protects yeast viability and fermentation performance in wine, beer, and bioethanol production.

Food & Beverage

Used in juice, gluconic acid, and condiment processing to decompose H₂O₂ before fermentation or packaging. Compliant with food additive regulations for direct food contact applications.

Wastewater Treatment

Rapidly neutralizes hydrogen peroxide in industrial effluent before discharge, reducing oxidant load and meeting environmental discharge limits for food, textile, and pharmaceutical sites.

Catalase Applications: Process Details, Dosage & Parameters

Processamento de Laticínios

Dairy | H₂O₂ Removal After Cold Pasteurization

Função: Cold pasteurization (H₂O₂ treatment) is used for raw milk pre-treatment in some markets, particularly where heat pasteurization is not available. Residual H₂O₂ must be completely removed before further processing. Catalase rapidly decomposes H₂O₂ to water and oxygen (2H₂O₂ → 2H₂O + O₂) without leaving any residue, meeting food safety requirements.

Dosagem típica: 100–300 U/L milk; add after H₂O₂ treatment; 5–15 minutes contact time at 4–20°C; verify complete H₂O₂ removal with peroxide test strip

Aplicações: Raw milk cold pasteurization, cheese milk preparation, H₂O₂-treated dairy in developing markets, whey processing.

Textile Processing

Textiles | H₂O₂ Neutralization After Bleaching

Função: Cotton bleaching uses H₂O₂ at 1–5 g/L to achieve fabric whiteness. Residual H₂O₂ after bleaching must be neutralized before dyeing — if H₂O₂ is present, it oxidizes and destroys reactive dyes, causing uneven color. Catalase neutralization replaces reducing agents (sodium bisulfite, sodium thiosulfate), reducing chemical cost and effluent load.

Dosagem típica: 100–500 U/L bath; 20–40°C; 10–20 minutes; pH 6–8; verify with H₂O₂ peroxidase test strip before dyeing

Aplicações: Cotton bleaching afterwash, hydrogen peroxide neutralization before reactive dyeing, textile mill effluent treatment.

Brewing & Fermentation

Brewing | Oxidative Stress Prevention

Função: H₂O₂ generated during mashing and fermentation causes oxidative damage to wort components and yeast cells, accelerating staling. Catalase addition protects sensitive flavor compounds and extends yeast viability during high-gravity fermentation. Also used in aeration systems to prevent H₂O₂ accumulation from enzymatic oxidation reactions.

Dosagem típica: 50–200 U/L; add to wort or fermentation vessel; compatible with standard yeast pitching conditions

Aplicações: High-gravity lager brewing, long-lagering fermentation, yeast health maintenance, flavor-sensitive specialty beer production.

Food & Beverage Processing

Food Industry | H₂O₂-Based Preservation Systems

Função: H₂O₂ is used as a sterilant for aseptic packaging (tetra pak, PET bottles) and as a cold antimicrobial treatment for fresh-cut produce and juices. Catalase provides controlled H₂O₂ neutralization after the sterilization treatment, ensuring no residual H₂O₂ in the final product.

Dosagem típica: 50–200 U/g product; 4–25°C; 5–15 minutes contact; combine with verification test for regulatory compliance

Aplicações: Aseptic packaging sterilization cleanup, fresh produce H₂O₂ wash treatment, juice cold preservation, food contact surface sterilization.

Wastewater Treatment

Industrial Effluent | H₂O₂ Neutralization

Função: Industrial processes using H₂O₂ (bleaching, sterilization, chemical synthesis) generate H₂O₂-containing effluent. Discharge of H₂O₂ above threshold levels (typically >1 ppm) is regulated due to aquatic toxicity. Catalase provides rapid, low-cost, environmentally clean H₂O₂ neutralization without adding reducing chemical residues.

Dosagem típica: 100–500 U/L effluent; ambient temperature; 10–30 minutes contact; pH 6–9; verify with peroxide test strip

Aplicações: Textile mill effluent, dairy wastewater, food processing discharge, pharmaceutical manufacturing effluent, hospital waste treatment.

Perguntas mais frequentes

Catalase (EC 1.11.1.6) is an oxidoreductase enzyme that decomposes hydrogen peroxide (H₂O₂) into water and oxygen: 2H₂O₂ → 2H₂O + O₂. It is one of the fastest enzymes known — one catalase molecule can decompose millions of H₂O₂ molecules per second. It leaves no chemical residue, making it ideal for food, textile, and environmental applications.
As a rule of thumb: 100–300 U/L catalase neutralizes 100–500 ppm H₂O₂ in 10–20 minutes at room temperature. For high H₂O₂ concentrations (>500 ppm), increase dosage proportionally. Always verify complete neutralization with a H₂O₂ peroxidase test strip before proceeding to dyeing, dairy processing, or packaging.
Minimum order is 1 kg for sample/trial. Commercial quantities in 25 kg drums and liquid totes. We stock food-grade and industrial-grade catalase. Most orders ship within 3–5 business days.
Yes — our food-grade catalase meets FAO/WHO and FCC specifications for use in dairy processing. It is produced by GRAS-recognized organisms (Aspergillus niger, Micrococcus lysodeikticus) and is approved as a processing aid in dairy applications in major markets including EU, USA, and Australia.
Typical fungal catalase: 10–50°C, pH 5–9; optimal at 30–40°C, pH 7. Bacterial catalase (Micrococcus): 10–60°C, pH 6–9; more heat-stable. For cold dairy processing (4–8°C), higher dosage compensates for reduced activity at low temperature. For textile applications (40–60°C), confirm grade temperature stability.
Yes — this is the primary textile application. Catalase neutralizes residual H₂O₂ (1–5 g/L) from cotton bleaching before reactive dyeing in 10–20 minutes at 25–40°C, replacing sodium bisulfite or sodium thiosulfate. This eliminates the need for lengthy hot rinse cycles and reduces effluent sulfite content significantly.
No — catalase acts as a processing aid and is inactivated by standard heat treatments (pasteurization or cooking). The enzyme protein is denatured and indistinguishable from other food proteins. No chemical residue is produced since the reaction only yields water and oxygen. Regulatory documentation confirming processing aid status is available.
Yes — catalase is commonly combined with laccase, peroxidase, and glucose oxidase in textile applications. In food processing, catalase is compatible with most hydrolases. In detergent formulations, catalase can protect other enzymes (amylase, protease) from oxidative inactivation by bleach components.
Catalase activity is measured in U/mL or U/mg — one unit decomposes 1 μmol H₂O₂/minute at pH 7.0, 25°C. Some suppliers use Kat (katal) or Baker units. Our product datasheets specify the assay and activity for each grade.
Liquid catalase: store at 2–8°C, use within 6–12 months. Powder catalase: ≤25°C, 12–18 months in sealed packaging. Catalase is sensitive to heat, heavy metals (Pb, Hg, Cu), and some surfactants — store away from these conditions. Always verify activity on receipt.
