Frequently Asked Questions
Which analytical methods (HPLC/GC) do you use for preservative quantification?
We use validated chromatography methods (HPLC) to precisely quantify accredited preservatives, including benzoic acid and sorbic acid, 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 test for aflatoxin?
Yes. We screen for total aflatoxin (B1, B2, G1, G2) by ELISA under our ISO/IEC 17025:2017-accredited method (SOP 097) to support FDA action levels and export limits for grains, nuts, spices, dried fruit, and dairy.
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, and vitamins) to generate a fully compliant, camera-ready Nutrition Facts Panel in accordance with FDA 21 CFR Part 101 standards.
Do you offer pet food and animal feed testing?
Yes. We perform accredited microbiological testing for pet food, treats, and raw diets — pathogen screening (Salmonella, Listeria, STEC), hygiene indicator counts, plus pH and water activity for stability.
How does Water Activity (Aw) testing ensure microbial safety and stability?
Water Activity (Aw) is a primary indicator of microbial growth risk. Testing this parameter helps define your product's shelf-life stability and regulatory classification (for example, 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 species 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. Our accredited allergen method covers Gluten/Gliadin (ELISA), and we provide screening for additional allergens such as peanut, soy, milk, and egg to verify "Free-From" claims and support 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 100 g (approximately 4 oz) of product to ensure we have enough representative sample for all tests.
