Overview
SIST ISO 941:1997 specifies an internationally recognized method for the determination of cold water-soluble extract in spices and condiments. Developed by the International Organization for Standardization (ISO) and adopted by the Slovenian Institute for Standardization (SIST), this standard outlines a precise laboratory procedure to quantify water-soluble components, such as certain flavor and aroma compounds, present in spice and condiment samples. The methodology includes detailed instructions for extraction, filtration, drying, and weighing, ensuring reliable, reproducible results across different laboratories and quality control environments.
Key Topics
- Test Methodology: Extraction of a defined portion of the spice or condiment sample using cold water, followed by filtration, drying of the extract, and weighing.
- Apparatus and Equipment: Standard laboratory apparatus such as volumetric flasks, pipettes, analytical balances, filter papers, ovens, and steam baths.
- Sampling Procedures: Reference to ISO standards for sampling (ISO 948) and ground sample preparation (ISO 2825) to ensure consistency.
- Result Expression: The extract content is expressed as a percentage by mass on a dry basis, offering accurate quantification of water-soluble matter.
- Reporting Requirements: Mandatory inclusion of operating conditions, sample identification, and any deviations or factors influencing outcomes in the test report.
Applications
The determination of cold water-soluble extract is a critical parameter in the quality control and specification of spices and condiments. Its practical applications include:
- Product Quality Assessment: Evaluating the purity, potency, and solubility characteristics of spice batches by measuring cold water-soluble content, which directly impacts flavor and aroma profiles.
- Manufacturing Consistency: Assisting producers and suppliers in maintaining standardized levels of solubility and extract quality according to international benchmarks.
- Regulatory Compliance: Supporting compliance with national and international food standards by providing a validated method for routine analysis.
- Research and Development: Facilitating comparative studies and product development in food science laboratories focused on optimizing spice blends and condiments for culinary applications.
Related Standards
To utilize SIST ISO 941:1997 effectively in laboratory and industrial settings, it is important to be familiar with the following related standards:
- ISO 948: Spices and condiments - Sampling - Guidelines for proper sampling techniques to ensure representative test portions.
- ISO 2825: Spices and condiments - Preparation of a ground sample - Procedures for preparing samples before analysis.
- ISO 943: Chemical analysis methods for spices and condiments that may complement or support cold water-soluble extract determination.
Practical Value
Adopting SIST ISO 941:1997 brings multiple benefits:
- Consistent Quality Assurance: Ensures reproducibility of results and comparability across different labs and production sites.
- Reliable Food Safety: Reinforces consumer trust through validated, standardized testing procedures for spice quality.
- International Trade: Facilitates smoother international transactions by aligning product specifications with universally recognized criteria.
By following this standard, laboratories and producers can guarantee the integrity and quality of spices and condiments, supporting both market requirements and consumer expectations.
