Abstract
Abstract A method for producing a cacao butter substitute which comprises cultivating a microorganism capable of producing fats and oils rich in 1,3-disaturated-2-unsaturated-triglycerides belonging to the genus Endomyces, Rhodotorula, Lipomyces or Rhodosporidium, such as Endomyces vernalis, Rhodotorula gracilis, Rhodotorula glutinis, Rhodotorula graminis, Rhodosporidium toruloides, Lipomyces starkeyi and Lipomyecs lipofer, under an aerobic condition, collecting the cells, isolating fats and oils rich in 1,3-disaturated-2-unsaturated-triglycerides from the cells, and optionally subjecting the fats and oils to fractionation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
48 words
A method for producing a cacao butter substitute, which comprises cultivating a Rhodosporidium toruloides microorganism capable of producing fats and oils rich in 1,3-disaturated-2-unsaturated triglycerides under an aerobic condition, collecting the resultant cells, and isolating a mixture containing fats and oils rich in 1,3-disaturated-2-unsaturated triglycerides from the cells.
Claim 2
Independent Claim
48 words
A method for producing a cacao butter substitute, which comprises cultivating a Rhodosporidium toruloides microorganism capable of producing fats and oils rich in 1,3-disaturated-2-unsaturated triglycerides under an aerobic condition, collecting the resultant cells, and isolating a mixture containing fats and oils rich in 1,3-disaturated-2-unsaturated triglycerides from the cells.
Claim 3
Dependent Claim
19 words
The method according to claim 1, wherein the isolated mixture containing the fats and oils is subjected to fractionation.
Claim 4
Dependent Claim
61 words
The method according to claim 2, wherein the fractionation is carried out by (1) removing the trisaturated triglycerides having a higher melting point by precipitating them from the mixture, (2) separating a fraction containing the desired 1,3-disaturated-2-unsaturated triglycerides from the mixture as the second precipitate, and (3) removing the liquid fraction containing monosaturated-diunsaturated triglycerides and triunsaturated triglycerides from the second precipitate.
Claim 5
Dependent Claim
29 words
The method according to claim 3, wherein the 1,3-disaturated-2-unsaturated triglycerides containing-fraction contains at least 15% by weight of the 1,3-disaturated-2-unsaturated triglyceride components based on the weight of said fraction.
Claim 6
Dependent Claim
21 words
The method according to claim 1, wherein the cultivation is carried out at a temperature of from 20° to 37° C.
