Enzymes for Food Safety Testing
Ensuring food safety is a cornerstone of global public health, regulatory compliance, and consumer trust. The rapid detection of contaminants, toxins, allergens, and pathogens is vital for maintaining food integrity across production, processing, and distribution chains. Enzyme-based analytical systems have become indispensable in modern food testing due to their high specificity, sensitivity, and compatibility with on-site and high-throughput platforms.
At Creative Enzymes, we provide a comprehensive range of diagnostic-grade enzymes optimized for food safety testing applications, including pathogen detection, toxin assays, adulteration analysis, and quality control of food ingredients. Our enzyme portfolio is engineered for superior catalytic performance, batch-to-batch reproducibility, and stability across varying pH, temperature, and matrix conditions—ensuring reliable results in diverse food environments.
| Pathogen Detection and Microbial Contamination | Enzyme-linked assays and biosensors play a central role in detecting foodborne pathogens such as Salmonella, E. coli O157:H7, and Listeria monocytogenes. Enzymes like alkaline phosphatase (ALP) and β-galactosidase act as reporter markers in immunoassays and chromogenic media, allowing rapid and visual identification of microbial colonies. Creative Enzymes supplies recombinant enzyme conjugates optimized for lateral-flow devices and ELISA systems used in routine quality testing by food producers and inspection laboratories. |

| Mycotoxin and Chemical Residue Testing | Mycotoxins such as aflatoxins, ochratoxin A, and fumonisins are among the most harmful food contaminants. Enzyme-linked immunoassays (ELISAs) employing horseradish peroxidase (HRP) or acetylcholinesterase (AChE) labels enable sensitive quantification of trace toxins. Our diagnostic-grade HRP and AChE show high activity retention in organic solvent environments and can be customized for integration into commercial toxin test kits or biosensors. |
| Allergen Detection | Food allergens (e.g., gluten, lactose, egg proteins, and nuts) are among the leading causes of hypersensitivity reactions. Enzymatic digestion assays using proteases and β-galactosidase are applied to detect trace allergenic residues in processed foods. Creative Enzymes offers enzymes that maintain activity under processing-level temperatures, improving assay robustness for industrial QC laboratories. |
| Detection of Food Adulteration and Authenticity Verification | Food adulteration—such as dilution of milk, addition of synthetic sweeteners, or mislabeling of meat species—poses major economic and safety concerns. Enzyme-based systems enable biochemical fingerprinting of authentic products. For example:
|
| Food Quality and Shelf-Life Indicators | Enzyme-mediated detection of oxidative stress markers, rancidity indicators, or microbial by-products supports quality control during storage.
|
| Biosensor and POCT Platforms for Food Safety | The convergence of enzyme catalysis with biosensor technology allows for fast and portable food testing solutions. Enzymes are immobilized on electrodes or nanomaterial surfaces to create electrochemical or optical biosensors capable of detecting contaminants in seconds. Creative Enzymes provides both native and engineered enzyme variants tailored for biosensor immobilization, ensuring high sensitivity, long operational stability, and compatibility with multi-analyte detection systems. |
Our food-safety enzyme line is manufactured under ISO 9001-compliant processes and undergoes QC/QA testing for activity, purity, stability, and reproducibility. Each batch is supplied with a Certificate of Analysis (CoA) and technical data sheet to ensure traceability.
In addition to our off-the-shelf catalog, we provide custom enzyme engineering, conjugation, and assay development services to meet client-specific food testing requirements—from prototype development to pilot-scale production for commercial diagnostic kits.
