Описание (английский):

La présente Norme internationale spécifie une méthode pour la détermination de l'alcalinité des corps gras d'origines animale et végétale sans faire de distinction entre leurs différents constituants. Cette méthode n'est pas applicable aux corps gras présentant une acidité supérieure à 60 % (fraction massique) déterminée conformément à l'ISO 660 et ne permet pas de déterminer si les corps gras fondus solides ont été traités avec des solutions caustiques.

Overview

SIST EN ISO 10539:2002 sets out a standardized method for the determination of alkalinity in animal and vegetable fats and oils. Developed by the European Committee for Standardization (CEN) in collaboration with ISO, this standard ensures consistency and accuracy in measuring alkaline content. It is a critical reference for laboratories, food producers, and quality assurance teams working with edible fats and oils.

The method applies to most animal and vegetable fats and oils, with exceptions for dry melted animal fats and high-acidity samples. By defining precise analytical procedures, this standard promotes reliable test results-essential for quality control, product labeling, and regulatory compliance in the fats and oils industry.

Key Topics

Scope and Applicability

Covers the determination of alkalinity in animal and vegetable fats and oils using titration with hydrochloric acid.
Not applicable to dry melted animal fats or to samples with more than 60% acidity, as per ISO 660.

Test Principle

A sample is dissolved in warm aqueous acetone and titrated with a standard hydrochloric acid solution.
The endpoint is determined by a color change, indicating the neutralization of alkaline constituents.

Sample Preparation

Follows guidance in ISO 661 for preparing test samples to ensure consistency.

Expression of Results

Alkalinity is reported as milligrams of sodium oleate per kilogram of sample, or as a percentage of sodium hydroxide.

Precision and Reliability

Details on repeatability and reproducibility are included, based on international interlaboratory studies.

Reporting Requirements

Specifies documentation and report elements needed to ensure traceability and comparability of results.

Applications

SIST EN ISO 10539:2002 is relevant for a wide range of practical applications, notably:

Quality Control in Food Production

Assists manufacturers of edible oils, margarine, and processed foods in verifying that products meet chemical specifications for alkalinity.
Facilitates detection of processing residues or accidental contamination by alkaline substances.

Regulatory Compliance

Supports compliance with local and international regulations concerning the quality and safety of animal and vegetable oils.

Laboratory Analysis

Provides a standardized approach for laboratories performing routine analysis of fats and oils, ensuring accuracy and comparability of results across different facilities.

Research and Product Development

Useful in product formulation and process optimization to manage the alkaline content of ingredients.

Related Standards

For comprehensive analysis and quality control of fats and oils, users should consult the following related standards:

ISO 660 - Determination of acid value and acidity in animal and vegetable fats and oils

ISO 661 - Preparation of test samples for fats and oils analysis

ISO 3696 - Specifications and test methods for water used in laboratory analysis

ISO 5555 - Sampling procedures for animal and vegetable fats and oils

ISO 5725 - Guidelines on accuracy (trueness and precision) of measurement methods and results

These standards, in conjunction with SIST EN ISO 10539:2002, provide a robust framework for the analytical assessment and quality assurance of animal and vegetable fats and oils. Adherence to these methodologies helps ensure product safety, regulatory conformity, and consumer trust in food products.
