Food Safety Evaluation
Engenium helps food manufacturers evaluate the physical safety of their products. We assess choking hazard potential and airway obstruction risk using Food Physical Safety (FPS) testing, biomechanics-based modeling, and injury data analysis.
Food Physical Safety (FPS) Testing
Food Physical Safety (FPS) testing evaluates the mechanical and rheological properties of food products to determine their potential to cause choking, airway obstruction, or oral injury during consumption. Unlike microbial or nutritional testing, FPS focuses exclusively on the physical characteristics of food—size, shape, bite behavior, dissolvability, and surface properties—that determine whether a product can become lodged in the airway or resist breakdown during normal eating.
Engenium's FPS program uses a series of assessments designed to model the mechanics of mastication (chewing) and ingestion (swallowing) across different age groups and consumer capabilities. Results are compared to a standardized comparator group of reference foods, allowing us to relate your product's performance back to quantifiable hazard potential.
-
Bite profile characterizes how a food product responds to compressive and shearing forces applied during the initial bite and throughout the mastication cycle. We measure force-displacement curves, fracture patterns, particle size distribution after first bite, and the transition from solid to bolus across multiple chewing strokes.
Why it matters: The bite profile determines whether a product fractures into dangerous shards, collapses into a manageable bolus, or resists breakdown entirely. Products with unpredictable fracture behavior, remain elastic after multiple bites, or form large, cohesive chunks may present elevated choking risk, particularly for consumers with limited dentition or chewing capabilities. Bite profile data is the primary input for age-grading decisions and texture modification recommendations.
-
Dissolvability rate measures how quickly a food product loses structural integrity when exposed to saliva or simulated oral fluids. We track mass loss, particle size reduction, and structural collapse over time intervals matching typical oral residence times.
Why it matters: Slow-dissolving foods remain in the mouth longer, increasing the window for airway entry during breathing, talking, or laughing. Rapidly dissolvable foods generally present lower choking risk for high-risk populations.
-
Lubricity evaluates the slipperiness of a food's surface and its ease of passage through the oral cavity and pharynx. We assess both intrinsic lubricity (natural moisture and fat content) and surface friction coefficients.
Why it matters: Highly lubricious, smooth, and spherical foods (e.g., grapes, cherry tomatoes, hard candy) can slide into the airway before the consumer has a chance to chew or swallow them properly. Low-lubricity, tacky foods may adhere to oral surfaces and require multiple swallowing attempts.
-
Tack (adhesiveness) measures the tendency of a food to stick to oral mucosa, teeth, dentures, or swallowing structures. We assess both initial adhesion and the work required to separate the food from contact surfaces.
Why it matters: Tacky foods (e.g., peanut butter, sticky candies, certain breads) can adhere to the posterior pharyngeal wall or laryngeal inlet, creating partial or complete obstruction that persists beyond the initial swallow.
Testing Methodology
Simulated Mastication
Using our physical hazard models, each product undergoes a battery of tests that replicate the mechanical forces, durations, and sequences of real-world eating
Age Specific Protocols
Not all consumers are the same. We understand that and analyze to fit the needs.
Interpretation
Your product's performance on each attribute is plotted against our comparator database of foods with established safety records. We use historical data, published literature, case studies, internal research, and evolving technology to continue strengthening our services.
Deliverables
Technical reports, designed to provide the insights and measurements to support action.
Frequently Asked Questions — Food Physical Safety
Q: How is FPS different from a standard texture analysis?
A: Standard texture analysis measures physical properties for quality control and product consistency. FPS testing specifically interprets those properties through the lens of choking hazard and airway obstruction risk, using age-specific thresholds and comparator benchmarks tied to injury data.
Q: Do I need FPS testing if my product already meets FDA food safety regulations?
A: FDA regulations primarily address microbial, chemical, and labeling safety. There are limited U.S. regulations governing the physical safety of food with respect to choking. The American Academy of Pediatrics has called for systematic evaluation of food-related choking hazards. FPS testing provides the data to demonstrate proactive risk management.
Q: Can FPS testing help me reduce liability?
A: Yes. FPS testing produces documented, defensible data showing that you evaluated and mitigated choking risk before bringing a product to market. This documentation can be critical in defending against product liability claims.
Q: How long does FPS testing take?
A: A standard FPS evaluation typically takes 2–4 weeks depending on product complexity, number of variants, and age groups assessed. Rush protocols are available.
Q: Do you test finished products or prototypes?
A: Both. We can evaluate finished commercial products, prototypes, reformulations, or competitor products for benchmarking purposes.
