Overview
ISO 14156:2001/Amd 1:2007 is an important amendment to the international standard ISO 14156, which specifies extraction methods for lipids and liposoluble compounds in milk and milk products. Developed jointly by the International Organization for Standardization (ISO) and the International Dairy Federation (IDF), this amendment refines existing procedures ensuring accurate and reliable lipid extraction for analytic and quality control purposes in dairy science.
This standardized methodology supports consistent analysis of lipid content, including fats and liposoluble molecules, crucial for nutritional, compositional, and regulatory assessment of milk-based products.
Key Topics
-
Method Applicability
The amendment clarifies that the extraction methods align with those described in other critical standards such as:
- ISO 12078|IDF 159 (Anhydrous milk fat – sterol composition determination)
- ISO 15884|IDF 182 (Preparation of fatty acid methyl esters)
- ISO 15885|IDF 184 (Fatty acid composition by gas-liquid chromatography)
- ISO 18252|IDF 200 (Routine sterol composition determination)
-
Cholesterol Extraction in Cheese
A notable addition addresses the specific extraction procedure when determining cholesterol content in cheese. The amendment specifies:
- Suspends the sample with approximately 4 g fat in 100 ml distilled water
- Details to follow the protocol of the base method (Clause 8.3) for complete cholesterol extraction
-
References and Bibliography Updates
The amendment updates key bibliographic references to include the newest relevant ISO/IDF standards related to milk fat analysis, legally strengthening the link between extraction procedures and compositional determination methods.
