Frequently Asked Questions

Which analytical methods (HPLC/GC) do you use for preservative quantification?
We use validated chromatography methods (HPLC/GC) to precisely quantify preservatives like benzoates, sorbates, and sulfites, ensuring your formulations meet specific FDA regulatory limits.
Can your lab detect heavy metals and pesticides at parts-per-billion levels?
Yes. Our advanced screening covers chemical contaminants, including heavy metals (Lead, Cadmium, Arsenic, Mercury) and pesticide residues, detecting them at trace levels to ensure raw material safety.
Do you provide FDA-compliant (21 CFR Part 101) nutritional analysis for food labeling?
Absolutely. Our nutritional analysis measures all mandatory nutrients (calories, fats, proteins, sugars, vitamins) to generate a fully compliant, camera-ready Nutrition Facts Panel according to FDA 21 CFR Part 101 standards.
How does Water Activity (Aw) testing ensure microbial safety and stability?
Water Activity (Aw) is the primary indicator of microbial growth risk. Testing this parameter helps define your product's shelf life stability and regulatory classification (e.g., for acidified foods under FDA rules).
How does accredited food hygiene testing improve product shelf-life?
Accredited hygiene testing assesses sanitation effectiveness. We analyze Aerobic Plate Count (APC), Yeast & Mold, and Coliforms to verify your manufacturing hygiene, preventing spoilage and extending freshness.
Does your pathogen screening cover STEC, Vibrio, and S. aureus?
Yes, we offer broad-spectrum detection for major foodborne pathogens including Shiga toxin-producing E. coli (STEC), Vibrio, Staphylococcus aureus, Bacillus cereus, and Campylobacter.
Should I test for Listeria spp. or Listeria monocytogenes for environmental monitoring?
For environmental monitoring (swabs), we recommend testing for Listeria spp. to find harborage sites. For finished products, we specifically confirm the absence of Listeria monocytogenes, the pathogen harmful to humans.
What is the fastest turnaround time for rapid Salmonella screening?
Salmonella is a zero-tolerance pathogen. We offer rapid detection methods that can deliver negative results in as little as 24–48 hours, allowing you to release inventory to market faster.
Do you conduct food allergen testing for labeling compliance?
Yes, we perform screening for major allergens including Gluten, Peanut, Soy, Milk, and Egg to verify 'Free-From' claims and ensure compliance with the Food Allergen Labeling and Consumer Protection Act (FALCPA).
How much sample quantity is generally required for testing?
For most standard chemical and microbiological analyses, we require a minimum of 100g (approx. 4 oz) of the product to ensure we have enough representative sample for all tests.
