Patent ID: 8911813

Claim:
A matrix building ingredient comprising a mixture of glycerol esters having the formula: wherein the R groups each represent an acyl fragment, wherein at least about 50 weight percent of the glycerol esters in the mixture have two of the R 1 , R 2 , and R 3 groups as long chain saturated fatty acid residues with between 14 to 24 carbon atoms inclusive and the remaining R group being a short chain acyl fragment with between 2 to 4 carbon atoms inclusive or a medium chain acyl fragment with between 6 to 12 carbon atoms inclusive, and of the glycerol esters having two of the R 1 , R 2 , and R 3 groups as long chain saturated fatty acid residues, there are more glycerol esters having long chain saturated fatty acid residues in adjacent glycerol positions than in terminal glycerol positions, wherein the matrix building ingredient comprises up to about 84 percent triglycerides with two long chain saturated fatty acid residues with at least about 56 percent of the triglycerides comprising 1,2-distearoyl-3-butyryl-glycerol.
