Tierische und pflanzliche Fette und Öle - Bestimmung der Alkalität (ISO 10539:2002)
Diese Internationale Norm legt ein Verfahren zur Bestimmung der Alkalität von tierischen und pflanzlichen Fetten und Ölen ohne Unterscheidung zwischen den verschiedenen Bestandteilen fest. Das Verfahren ist nicht anwendbar auf trocken geschmolzene tierische Fette und Öle und auf Fette und Öle mit einer Acidität über 60 % (Massenanteil), bestimmt nach ISO 660.
ANMERKUNG Fette und Öle können alkalische Bestandteile enthalten, entweder natürlichen Ursprungs (z. B. Calciumseifen aus Knochen) oder durch zufällige Zusätze (z. B. Natriumseifen in ungenügend raffinierten Fetten und Ölen).

Overview
EN ISO 10539:2002 is an international standard developed by the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO). It specifies a reliable and precise method for the determination of alkalinity in animal and vegetable fats and oils. This standard provides a unified procedure for measuring alkaline constituents in fats and oils using titration techniques.
Alkalinity in fats and oils can arise naturally, such as calcium soaps from bones, or accidentally, such as sodium soaps from imperfect refining. This standard applies to various fats and oils except dry melted animal fats or oils with high acidity exceeding 60% as per ISO 660.
Key Topics
- Scope: Specifies determination of alkalinity without differentiating among various alkaline constituents.
- Sample Preparation: Detailed methodology for preparing test samples according to ISO 661 to ensure accurate results.
- Reagents & Apparatus: Utilizes aqueous acetone with bromophenol blue indicator and standardized hydrochloric acid solution for titration.
- Analytical Method: The alkalinity is determined by dissolving the fat or oil sample in warm aqueous acetone and titrating against hydrochloric acid until a specific color change is observed.
- Expression of Results: Alkalinity results can be expressed as milligrams of sodium oleate per kilogram of sample or as a percentage mass fraction of sodium hydroxide.
- Precision and Repeatability: Includes interlaboratory test results ensuring consistency and reproducibility of results, supported by statistical data table with repeatability and reproducibility limits.
- Reporting: Specifies requirements for documenting all relevant test conditions, sample identification, and raw or validated results.
Applications
EN ISO 10539:2002 serves a critical role in the quality control and analysis of animal and vegetable fats and oils across various sectors:
- Food Industry: Ensures compliance with quality standards in edible fats and oils by detecting alkaline impurities that could affect taste, safety, and shelf life.
- Cosmetics and Pharmaceuticals: Supports accurate chemical characterization of fats and oils used in formulations where alkalinity influences product performance and stability.
- Industrial Processing: Assists refineries and processing plants in monitoring refining efficiency and residual soap content.
- Research and Development: Provides standardized measurement techniques for scientific studies related to fat and oil chemistry and processing methods.
- Regulatory Compliance: Helps regulatory bodies monitor product standards and enforce consistent quality in fats and oils supplied to markets.
Related Standards
This standard references several important normative documents, forming a comprehensive framework for fats and oils testing:
- ISO 660: Determination of acid value and acidity of fats and oils.
- ISO 661: Guidelines for preparation of test samples.
- ISO 3696: Standards for laboratory water quality used in chemical analysis.
- ISO 5555: Sampling methods for animal and vegetable fats and oils.
- ISO 5725 series: Methods for evaluating repeatability and reproducibility of measurement techniques.
Together, these standards ensure laboratories can achieve high-quality, reproducible, and internationally accepted test results for animal and vegetable fats and oils.

ISO 10539:2002(E) © ISO 2002 – All rights reserved iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
