Human breast milk lipid mimetic as a dietary supplement

A substitute human milk fat composition comprising a blend of at least 25% to 50% of a fat base composition which fat base composition comprises a mixture of processed vegetable oils, with from 50% to 75% of at least one enzymatically-randomized vegetable oil, wherein the fat base composition is produced by reacting a palmitic acid-rich vegetable oil comprising above 78% palmitic acid residues with unsaturated fatty acids comprising above 75% oleic acid residues in the presence of an insoluble catalyst, removing the catalyst, and distilling any free fatty acids,

• wherein over 90% of the fat base composition are a mixture of triglycerides in which mixture:

• at least 70% w/w of fatty acid residues attached at the sn-1 and sn-3 positions of the glycerol backbone of the triglycerides are unsaturated fatty acid residues;
• from 6 to 17% w/w of unsaturated fatty acid residues at the sn-1 and sn-3 positions of the glycerol backbone of the triglycerides are linoleic acid residues;
• and
• from 40 to 60% w/w of unsaturated fatty acid residues at the sn-1 and sn-3 positions of the glycerol backbone of the triglycerides are oleic acid residues;
• and
• wherein the blend is prepared by admixing the fat base composition with the at least one enzymatically-randomized vegetable oil, and in which blend:
• from 22 to 33% w/w of total fatty acid residues are palmitic acid residues;
• from 33 to 57% w/w of fatty acid residues attached at an sn-2 position of the glycerol backbone of the triglycerides are palmitic acid residues;
• from 48 to 69% w/w of the total palmitic acid residues of the triglycerides are attached at the sn-2 position of the glycerol backbone of the triglycerides;
• from 33 to 48% w/w of fatty acid residues are oleic acid residues;
• and
• from 8 to 23% w/w of fatty acid residues are linoleic acid residues.

• and
• from 40-60% w/w of the unsaturated fatty acid residues at the sn-1 and sn-3 positions of the glycerol backbone of the triglycerides are oleic acid residues.
