Overview
ISO 11035:1994 defines a structured, multidimensional approach for identifying and selecting descriptors used to establish a sensory profile of a product. The standard covers both the qualitative task of defining descriptors that distinguish a product from others of the same type, and the quantitative task of evaluating the intensity of each descriptor. It describes the stages for setting up sensory tests that together produce a complete description of a product’s sensory attributes.
Key topics
- Descriptor generation and selection - systematic identification of terms (attributes) that capture relevant perceptions of appearance, aroma, flavor, texture and other sensory dimensions.
- Multidimensional profiling - combining multiple descriptors to form a comprehensive sensory profile rather than relying on single-attribute tests.
- Qualitative vs quantitative assessment - defining descriptors (qualitative) and measuring their intensity (quantitative) to create reproducible profiles.
- Test planning - stages and considerations for designing sensory assessments that yield consistent and interpretable descriptor lists.
- Data consistency and reproducibility - using selected descriptors to standardize sensory description across assessors and tests.
Practical applications
ISO 11035 is practical for any organization needing rigorous sensory characterization of products. Typical applications include:
- Product development and improvement - identify target sensory attributes and track changes during reformulation.
- Quality assurance and production standards - define sensory specifications for consistent product release.
- Shelf‑life and storage studies - monitor how ageing and storage conditions alter sensory attributes over time.
- Benchmarking and market comparison - compare products to competitors using a common descriptor set.
- Research and validation - create standardized profiles for publication or internal validation.
Who should use it
- Sensory scientists and panel leaders
- R&D teams in food & beverage, cosmetics, fragrances, and consumer goods
- Quality assurance and product managers
- Academic researchers in sensory evaluation and consumer science

ISO 11035 complements other sensory analysis guidance such as standards on sensory vocabulary, panel selection and training, and profiling methodologies. Use ISO 11035 together with those guidelines to ensure consistent terminology, trained assessors, and robust sensory profiling.
