Overview
EN ISO 8586:2023 - Sensory analysis: Selection and training of sensory assessors (ISO 8586:2023) defines criteria and procedures for recruiting, pre‑screening, training and validating sensory assessors and expert sensory assessors. Adopted by CEN and applicable across industries that evaluate products by the sense organs (notably food and beverages, home and personal care). EN ISO 8586:2023 supersedes the 2014 edition and supplements the guidance in ISO 6658.
Key topics and technical requirements
This standard covers practical, technical steps to ensure reliable sensory data and repeatable assessments. Major topics include:
- Recruitment and preselection - principles for identifying candidate assessors, internal vs external recruitment, and the number of persons needed.
- Sensory screening tests - procedures to detect sensory impairments and confirm capabilities (colour vision, smell - anosmia/ageusia checks, texture discrimination, hearing, descriptive ability).
- Training program design - structured exercises for detecting stimuli, intensity discrimination, descriptive ability, and use of scales; product‑specific training and method‑specific practice (ranking, rating, descriptive analysis).
- Assessment procedures and validation - methods to evaluate assessor performance, panel validation, and measuring training effectiveness.
- Panel management and follow‑up - maintaining skills, motivation, retraining, renewal of panel members and ongoing monitoring.
- Informative annexes - practical aids such as alternative colour screening, texture difference recognition, palate cleansers, scale examples, and sample exercises.
Practical applications
EN ISO 8586:2023 is used to build robust sensory panels and ensure data quality in:
- Product development and formulation trials (food, beverages, cosmetics, household products)
- Quality control and lot acceptance testing
- Competitive benchmarking and shelf‑life studies
- Descriptive sensory analysis for flavour, texture and aroma profiling
- Consumer insight studies where trained panels provide reference data
Benefits include improved reproducibility and validity of sensory results, reduced assessor bias, and clearer documentation for audits and regulatory compliance.
Who should use this standard
- Sensory scientists and panel leaders
- R&D teams and product developers
- Quality assurance/quality control (QA/QC) laboratories
- Contract testing laboratories and third‑party sensory providers
- Regulatory bodies and certification schemes that rely on standardized sensory evaluation
