EXPLANATION
Milk Fat Globule Membrane
- Phospholipid Distribution Across Dairy Fractions:
- Enrichment in Buttermilk:
- Milk phospholipids are predominantly concentrated in the Milk Fat Globule Membrane (MFGM).
- During churning of cream into butter, mechanical agitation ruptures fat globule membranes, releasing MFGM polar lipid fragments into the aqueous buttermilk.
- Consequently, buttermilk is the richest dairy source of phospholipids ($0.15 - 0.20\%$, or $\approx 5\times$ higher than whole milk).
- Conclusion: Butter milk (Option 2).
Correct option: (2) Butter milk
