Dairy lipids (fat) analysis:
• Total lipids % (Fat content) – Extraction
• Fatty acids (AA, EPA, DHA, trans-FA) – Gas chromatography
• Phospholipids – 31P-NMR
• Cerebrosides – LC-MS/MS
• Gangliosides – Extraction & LC-MS/MS
• OPO analysis – RP-LC (preparative), Ag+-LC (analytical) Shimadzu LCMS-8040
Agilent GC 7890B

New EU regulation requirements for infant formulas (from 2020):• trans fatty acids <3% (of total fat) • erucic acid 22:1n-9 <1% (of total fat)• 18:2n-6 (500-1200mg per 100kcal)• 18:3n-3 (50-100mg per 100kcal)• DHA (20-50mg per 100kcal)• AA <1% (of total fat)• omega6 <2% (of total fat)• EPA ≤ DHA.
