A Leader’s Guide to Sensory Evaluation in R&D and Quality Control
Discover how sensory evaluation supports food innovation, quality assurance, and consumer preference through data-driven sensory evaluation methods.
Consumer expectations are complex and driven by experience. At Mérieux NutriSciences, our sensory experts identify the specific drivers of consumer preference through artfully crafted studies. We provide the critical data needed to optimize formulations and ensure your product attributes are favorable before market launch.
Choosing the right environment is critical for data integrity. We utilize our robust consumer database—including specialized adult and child demographics—to ensure your formulations are assessed by your exact target audience.
Central Location Testing (CLT)
Conducted at our state-of-the-art sensory laboratories, CLTs offer a neutral, controlled environment. This setting is vital for ensuring consistency, gathering objective data, and allowing for real-time professional oversight.

Example of a CLT comparative analysis measuring consumer liking across key sensory modalities.
In-Home Use Testing (IHUT)
IHUT allows products to be assessed in their natural, functional environments. This method provides authentic feedback on sensory attributes and user experience, identifying how products perform when prepared and consumed in the home.
Our consumer testing is a critical component of our broader Sensory Evaluation Services, providing the qualitative context to our quantitative data.

To receive a tailored proposal, you can schedule a technical consultation with our sensory scientists. We evaluate your specific research goals—such as formulation optimization or claims substantiation—and design a custom study protocol that aligns with your timeline and budget requirements.
In-person CLT occurs in a sterile, controlled laboratory, ensuring every participant experiences the product under identical conditions—ideal for bench-marking and prototype screening. Online-enabled IHUT allows consumers to prepare and use products in their own homes, providing authentic feedback on functionality, preparation habits, and long-term satisfaction.
The primary benefit is the total control over environmental variables that could otherwise skew data. At a centralized facility, every participant experiences the product under identical lighting, temperature, and preparation protocols. This neutral environment eliminates "noise" from the home setting, allowing our Sensory Scientists to capture highly precise, objective data—making it the ideal choice for prototype benchmarking and sensory discrimination testing.
The industry primarily utilizes Central Location Testing (CLT) for controlled, objective product assessments and In-Home Use Testing (IHUT) to evaluate performance in natural environments. At Mérieux NutriSciences, we integrate these methods to provide a holistic view of consumer perception, from initial acceptance to functional usage.
The process begins with defining the ideal consumer profile, followed by a rigorous screening survey to filter for brand usage, allergens, and sensory acuity. Once identified, participants are scheduled into a controlled environment where their feedback is captured using standardized sensory ballots to ensure the results are statistically significant and actionable.
Reputable recruitment relies on a robust, validated consumer database. Mérieux NutriSciences maintains an extensive database of diverse demographics, including specific age groups and lifestyle segments. Our "artfully crafted" screening process ensures that participants strictly match your target consumer profile for high-integrity data.
CLT is best suited for products that require specialized handling, strict temperature control, or complex preparation that cannot be reliably replicated in a consumer’s home. This includes sensitive categories such as alcohol, nicotine, and dietary supplements, as well as products where immediate, real-time feedback is required under expert supervision. By utilizing a controlled lab, we ensure that the integrity of the product and the resulting data remain uncompromised.
