Calculating the iodine value for marine oils from fatty acid profiles

摘要

The iodine values of marine oils were directly calculated from fatty acid profiles by using reacting ratios calculated from fatty acid profiles by using reacting ratios (calculation factors) between I-2 (iodine) and either the fatty acids bound to a triglyceride or the free fatty acids. A total of 20 factors were incorporated from C14:1 to C24:1, placed into an Excel(R) spreadsheet, and used to calculate the iodine values. The calculated values were then compared to the oil's iodine value obtained by the traditional titration method. The results indicate that this method can be used to obtain the iodine value of marine oils directly from the oil's fatty acid composition, thus giving two results from one analysis. [References: 4]
