Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
76 words
A SYNTHETIC TRIGLYCERIDE FAT WHICH COMPRISES AN INTERESTERIFIED MIXTURE OF AT LEAST TWO FATTY TRIGLYCERIDE COMPOSITIONS, EACH OF SAID FATTY TRIGLYCERIDE COMPOSITIONS HAVING A SUBSTANTIALLY STABLE BETA CRYSTAL STRUCTURE, SAID MIXTURE CONTAINING FATTY ACYL COMPONENTS APPROXIMATING 73-80% C15 ACIDS AND 20-27% C16 ACIDS OF THE TOTAL C16 AND C18 ACIDS, THE C16 AND C18 ACIDS COMPRISING AT LEAST 95% OF THE TOTAL ACIDS, THE FATTY-ACYL RADICALS BEING RANDOMLY REDISTRIBUTED BETWEEN THE GLYCERYL RADICALS OF THE MIXTURE.
