Abstract
In order to obtain more information on the properties or specific features of egg yolk lipids, this study was undertaken to determine fatty acid and triglyceride composition of egg yolk lipids from the pheasant, copper pheasant, turkey and peacock.
The total and neutral lipids of eggs from pheasant and copper pheasant contained more of C18: 1 acid than the others.
The egg yolk phospholipids from turkey and peacock contained more of C16: 0 and C18: 1 acids than pheasant and copper pheasant.
The majority of acids linked at 2-position in yolk triglycerides were C18: 1 and C18: 2, and C16: 0 or C18: 0 acids were predominantry linked at 1, 3-position in egg yolk triglycerides.
The most abundant triglyceride in yolk lipids was monosaturated triglyceride (SU2), then followed by disaturated triglyceride (S2U) and triunsaturated glyceride (UUU), and trisaturated glyceride (SSS) was the least. And, it was considered that the major component triglyceride in yolk lipids were POO, PLO, OOO, POL, PLP, OLO, POPt and etc.
As a results of this experiment, the differences in amounts of some component triglycerides in yolk lipids were observed among species of birds tested, but in generel, it may be said that egg yolk lipids from birds studied here rather had an analogous feature on their triglyceride composition.
