What is Catalase From Penicillium Notatum?
Catalase from Penicillium notatum is an enzyme derived from the fungus Penicillium notatum. Catalase is a naturally occurring enzyme found in most living organisms that catalyzes the decomposition of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen (O₂). The enzyme used as a food additive is produced through fermentation of the Penicillium notatum strain and subsequently purified for food applications.
Common Uses
This enzyme is primarily used in food manufacturing as a processing aid to remove residual hydrogen peroxide. Hydrogen peroxide is commonly used in food processing for bleaching, disinfection, and sterilization purposes—particularly in dairy processing, juice production, and starch manufacturing. After these processes, catalase is added to break down any remaining hydrogen peroxide into harmless water and oxygen, ensuring the final food product does not contain dangerous peroxide residues.
The enzyme also serves antimicrobial functions by contributing to food preservation processes. It may be used in conjunction with other processing techniques to support food safety during manufacturing.
Safety Assessment
Catalase from Penicillium notatum has received Generally Recognized as Safe (GRAS) status from the FDA, indicating that the agency has concluded it is safe for its intended use in food. The enzyme has an excellent safety record, with zero reported adverse events and zero FDA recalls associated with this additive. This reflects both the inherent safety of the enzyme and its appropriate use in food manufacturing at specified levels.
As an enzyme, catalase is a protein that is broken down by digestive enzymes in the human gastrointestinal tract, similar to other dietary proteins. The end products of catalase decomposition are the same amino acids found in normal protein metabolism, making systemic absorption of intact enzyme unlikely. The hydrogen peroxide that catalase breaks down is completely eliminated through this enzymatic reaction, leaving only water and oxygen as byproducts.
The source organism, Penicillium notatum, has a long history of safe use in food and pharmaceutical applications. This fungal strain was first identified as the source of penicillin and has been extensively studied over decades.
Regulatory Status
Catalase from Penicillium notatum is affirmed as GRAS by the FDA under 21 CFR 184.1645. This regulatory status means the enzyme may be used as a food additive without pre-market approval, provided it is used in accordance with good manufacturing practice and within specified functional purposes.
The enzyme is recognized in international food safety frameworks and is approved for use in food manufacturing in multiple jurisdictions. Its GRAS status is based on scientific evaluation of safety data and the enzyme's long history of safe use in food production.
Key Studies
The GRAS determination for catalase from Penicillium notatum was based on comprehensive safety evaluations. These assessments considered the source organism's safety history, the enzyme's function and specificity, potential toxicity, and allergenicity. The enzyme's well-characterized mechanism of action—simple decomposition of hydrogen peroxide into harmless components—supports its safety profile.
Literature on catalase enzymes generally demonstrates their safety across numerous applications. The enzyme's rapid and complete breakdown of hydrogen peroxide, combined with the protein nature of the enzyme itself, presents minimal food safety concerns when used as directed in food manufacturing processes.
