Why Chemical Testing of Food Matters

Chemical contaminants, mislabeled ingredients, nutrient deviations, and formulation inconsistencies represent major risks. Chemical testing of food helps identify hazardous substances, verify label claims, evaluate degradation, and detect adulteration.
Whether you are validating raw materials, ensuring finished product compliance, or supporting shelf-life stability studies, AGT Labs delivers accurate results designed to meet FDA, EPA, and international safety standards.

Frequently Asked Questions

Common questions about our chemical testing services for food products.

What is included in a standard Proximate Analysis?

A standard Proximate Analysis includes five core tests: Moisture, Protein, Fat, Ash (minerals), and Carbohydrates (calculated), which provides the foundation for general nutritional data.

How do you determine if an oil or fat has gone rancid?

We perform a Rancidity Panel including Peroxide Value (PV) to measure primary oxidation and Free Fatty Acids (FFA) for hydrolytic degradation, giving you a clear picture of oil quality.

Does your testing distinguish between Total Sugars and Added Sugars?

Yes. We use HPLC sugar profiling to distinguish naturally occurring sugars (like fructose in fruit) from added sugars, ensuring your Nutrition Facts panel meets the updated FDA requirements.

What is the difference between Moisture Content and Water Activity?

Moisture measures total water amount, while Water Activity (Aw) measures available water for microbial growth. Both are crucial for shelf stability but serve different preservation purposes.

Can you test for specific vitamins to verify label claims?

Yes, our accredited lab verifies potency for Vitamin A, C, D, and various B-vitamins using HPLC methods to support label claims and monitor stability over time.

How are Prop 65 Heavy Metal limits calculated for my product?

We customize our ICP-MS detection limits to meet specific "Safe Harbor" levels for Lead, Cadmium, Arsenic, and Mercury based on your product's daily serving size to assess Prop 65 compliance.

Do you test for Sudan Dyes or other illegal colorants?

Yes, we screen for unauthorized chemical dyes like Sudan I-IV, Para Red, and Rhodamine B, which are strictly prohibited in food products due to safety concerns.

What chemical markers are monitored in a shelf-life study?

We monitor chemical degradation markers over time, such as pH stability, water activity shifts, rancidity (PV/FFA), and vitamin potency loss, incubated at specific temperatures.
