초록
Capillary column GLC 및 GCMS를 병용하는 분석방법을 이용하여 식물유 트리글리세리드 분자종과 산화안정성과의 관계를 밝히기 위해서, 규산 컬럼으로 분획한 대두유 트리글리세리드를 모델 시료로 하여
The influence of triglyceride molecular species on autoxidation was investigated by determining the residual molecular species after incubating soybean oil triglycerides. The molecular species of soybean oil triglycerides were analyzed by capillary column gas chromatography and electron impact ionization mass spectrometry utilizing selected ion monitoring. The autoxidative stability of each molecular species in soybean oil triglycerides appeared to decrease in proportion to the increase in the number of double bonds present in the acyl residues, and it was affected by degree of unsaturation of fatty acid when the number of double bonds in triglyceride were the same. And it appeared to be enhanced by a decreases in the length of the saturated acyl chain present in the glycerides.
