Overview
ISO 13302:2003 - Sensory analysis - Methods for assessing modifications to the flavour of foodstuffs due to packaging is an international standard developed by ISO. It provides a systematic approach for evaluating how packaging materials may alter the sensory attributes, particularly flavour, of food products and their simulants. The standard applies to all packaging materials (such as paper, cardboard, plastic, foils, and wood) and can be extended to any object intended to come into contact with food, including kitchen utensils, coatings, and certain equipment parts. This ensures food compatibility and safety from a sensory (taste and smell) perspective, aligned with current food legislation.
Key Topics
- Sensory Analysis in Packaging: Guidelines describe how to assess both the inherent odour of packaging materials and their potential to modify food flavours. Sensory analysis includes both direct and indirect food contact scenarios.
- Test Methodologies: The standard outlines several sensory test methods such as odour testing, paired comparison, triangle, duo-trio, ranking, and scoring tests. It also details procedures for preparing samples, proper storage, and container usage.
- Assessment of Foodstuff-Flavour Changes: ISO 13302:2003 explains how to expose food samples to packaging materials under controlled conditions and then assess any flavour modifications using trained sensory panels.
- Risk Assessment and Acceptance Criteria: Provides guidance for manufacturers in both the development and routine production stages to identify the risk of flavour modification from new packaging or individual batches, enabling immediate corrective action if issues are detected.
- Reporting Requirements: The standard sets forth the information that must be included in test reports, such as sample identification, test conditions, assessor qualifications, and results.
Applications
ISO 13302:2003 is a valuable tool for:
- Packaging Material Selection: Assists food businesses in preliminary evaluation to select packaging materials that will not negatively affect the sensory qualities of their products.
- Quality Control in Production: Allows for screening individual batches to ensure continued food compatibility and consumer satisfaction by detecting taints or off-flavours introduced during manufacturing.
- Compliance with Food Safety Legislation: Supports regulatory compliance by providing documented evidence and traceability regarding the sensory neutrality of packaging in contact with food.
- Product Development: Aids in the research and development of new packaging solutions, ensuring that any innovations meet sensory acceptability standards before market launch.
- Evaluation of Food-Contact Objects: Extends beyond packaging to include kitchen utensils, machinery components, and other items intended to contact food, monitoring for potential flavour alterations.
Related Standards
ISO 13302:2003 references and is designed to work alongside several other international standards focused on sensory analysis and food packaging, including:
- ISO 4120: Sensory analysis - Methodology - Triangle test
- ISO 5492: Sensory analysis - Vocabulary
- ISO 5495: Sensory analysis - Methodology - Paired comparison test
- ISO 6564: Sensory analysis - Flavour profile methods

Practical Value
Implementing ISO 13302:2003 ensures that food businesses can scientifically assess and document the sensory impact of packaging, thereby protecting product quality and brand reputation. By integrating sensory analysis into packaging selection and quality assurance processes, manufacturers reduce the risk of consumer complaints and regulatory non-compliance, and foster innovation through validated, sensory-neutral packaging solutions. The standard is also a critical part of broader food safety and quality management systems, emphasizing both consumer safety and satisfaction.
