Food Testing

Comprehensive Testing Services

United Food Labs is a full-service, ISO-certified laboratory specializing in food testing, beverage testing, dietary supplement analysis, and pet food testing. We provide free consultations to help you navigate FDA compliance, product safety, and testing requirements with confidence.

Shelf Life Testing

We offer a range of shelf life studies to evaluate product stability, safety, and quality over time:

Isotherm Accelerated Shelf Life Studies
Evaluate product stability (protein bars, powders, low moisture products) under controlled temperature conditions to predict shelf life.
Oxidative Accelerated Shelf Life Studies
Assess oxidation-related degradation (rancidity, off-flavors, nutrient loss), especially for fat-containing products.
Accelerated & Real-Time Shelf Life Studies
- Accelerated studies simulate long-term storage in a shorter timeframe
- Real-time studies monitor products under normal storage conditions for accurate shelf life determination

Process Authority Letters & Microbial Validation Testing

We provide Process Authority Letters for acidified foods, low-acid foods, and shelf-stable beverages to ensure FDA and 21 CFR compliance. Our team evaluates your formulation, pH, water activity (aw), and thermal processing methods (including hot fill) to validate product safety and regulatory requirements. Ideal for brands needing process validation, scheduled processes, and challenge studies (microbial validation testing)
