| Abstract: | To determine the fatty acids in milk and dairy products.The fatty oils of milk and dairy products were extracted by Rose-Gettlieb method,the fatty acids in the fatty oils were esterified by potassium hydroxide-methanol,and then analyzed by gas chromatography-mass spectrometry(GC/MS).The results indicate that main fatty acids' carbon chain were from 8 to 24,each fatty acid has different conent in different samples and the content was determined by area normalization. |
| Keywords: | Milk and dairy products Fatty acid GC/MS Separation and identificaton |
