Standard Test Method for Determination of Neutral Fatty Matter Contained in Fats and Oils
SIGNIFICANCE AND USE
3.1 This test method is intended for the determination of the neutral fatty matter contained in fats and oils by means of ether extraction.
SCOPE
1.1 This test method covers all degraded glycerides, since they are neutral fats. However, this procedure does not necessarily determine all the mono and diglycerides that may be present in the sample. This is due to the water soluble characteristics of some mono and diglycerides.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D5560-95(2018) is a standardized test method developed by ASTM International for the determination of neutral fatty matter contained in fats and oils. This method, primarily based on ether extraction, is widely recognized in the fats and oils industry for its ability to quantify degraded glycerides, commonly referred to as neutral fats. While this test covers a broad spectrum of neutral fatty compounds, it may not capture all mono- and diglycerides due to their water-soluble characteristics.
The standard helps laboratories and quality control professionals in the food, chemical, and leather industries evaluate the composition of fats and oils, ensuring product quality, safety, and compliance with international guidelines. Developed in accordance with World Trade Organization (WTO) TBT Committee principles, this standard aligns with global trade requirements.
Key Topics
Scope and Limitations
- Applicable to all degraded glycerides (neutral fats) in fats and oils.
- Does not necessarily quantify all mono- and diglycerides due to water solubility.
- SI units are used throughout; other measurement systems are not included.
Test Method Significance
- Utilizes ether extraction to isolate neutral fatty matter.
- Involves titration, extraction, and evaporation procedures.
Reproducibility and Safety
- Originally adopted from American Leather Chemists Association procedures.
- Users are responsible for establishing safety and regulatory processes suited to their operations.
- Emphasizes the need for reference materials to ensure accuracy and precision.
Compliance and Standardization
- Developed under WTO TBT Committee principles for international consistency.
Applications
The ASTM D5560-95(2018) test method is crucial for a range of industries that rely on accurate quantification of neutral fatty matter in fats and oils:
Food Industry
- Helps verify the compositional purity and quality of edible oils and fats.
- Supports labeling compliance and quality assurance programs.
Chemical Manufacturing
- Used in the analysis of raw materials and finished products, including lubricants and cosmetics, where fat composition impacts product properties.
Leather Industry
- Assists in the assessment of oils and fats used in leather processing, ensuring adherence to required material properties.
Research and Development
- Facilitates studies on fat degradation, process optimization, and product innovation.
