Overview
SIST ISO 5561:1997 is an international standard established by the International Organization for Standardization (ISO) that specifies the requirements for whole black caraway and blond caraway (Carum carvi Linnaeus). It defines criteria for product quality, sampling methods, testing protocols, packaging, and marking. This standard applies exclusively to Carum carvi and excludes Carum bulbocastanum. By adhering to SIST ISO 5561:1997, producers and suppliers ensure the consistency, safety, and authenticity of these caraway varieties for global trade and consumption.
Key Topics
-
Scope and Applicability
Covers whole black caraway (biannual fruiting) and blond caraway (annual fruiting), highlighting the physical and chemical specifications that differentiate these two forms.
-
Product Description
- Black caraway: 4 to 6 mm in length with curved, pale yellow to ochre ribs and brown intercostal surfaces.
- Blond caraway: Similar shape but slightly larger and paler in color.
-
Quality Requirements
- Must be free from live insects, molds, and fungal infections (notably Sclerotinia).
- Not more than 1% by weight of foreign matter (non-caraway plant parts, animal, mineral, or other vegetative impurities).
- Characteristic aromatic flavor and absence of off-odors including moldy or foreign smells.
-
Chemical Specifications
- Maximum moisture content: 13% for black caraway and 12% for blond caraway.
- Total ash (dry matter) max 8%.
- Acid-insoluble ash max 2%.
- Essential oil content minimum 2.5% for black caraway and 1.95% for blond caraway, measured immediately after grinding.
-
Sampling and Testing
Sampling must comply with ISO 948. Samples are ground (per ISO 2825) and sieved through 500 μm mesh for analysis. Specific test methods referenced include ISO 927 for foreign matter, ISO 930/928 for ash, ISO 939 for moisture, and ISO 6571 for essential oils content.
-
Packaging and Marking
- Packaging must protect against moisture, contamination, and loss of volatile oils.
- Containers should be clean, dry, and made of material inert to the product.
- Labels must include product name (botanical and commercial), producer/packer details, batch number, net weight, country of origin, and any client-specific information.
- Reference to SIST ISO 5561:1997 must be stated on the packaging.
-
Storage and Transport Recommendations
- Store in enclosed, well-ventilated, dry conditions free from pests, odors, and direct sunlight.
- Prevent exposure to excessive heat or moisture during transport and storage, particularly in ship holds.
- Fumigation might be necessary to ensure product safety.
Applications
SIST ISO 5561:1997 is primarily used by:
- Agricultural producers and farmers who cultivate and harvest black and blond caraway.
- Spice exporters and importers to ensure international quality compliance and facilitate trade.
- Food processors and spice manufacturers requiring standardized raw materials with verified chemical and sensory profiles.
- Quality control laboratories conducting official sampling and testing for conformity to internationally recognized benchmarks.
- Packaging and logistics providers ensuring optimal handling, storage, and transport conditions preserving product quality.
Compliance with this standard helps maintain product integrity, supports market access, and reassures end-users about the safety and authenticity of caraway seeds.
