Book excerpt: This project involves the simultaneous quantification of the fat soluble vitamins D and E in baby food using hypercarb column and the simple general lipid extraction method. The quantification of the vitamin D3 and E were achieved by using a calibration curve with linearity of 25ug/ml - 400ug/ml and r2 of 0.9602 for vitamin D3, whiles the vitamin E was done by using a calibration curve with linearity of 10ug/ml - 200ug/ml and r2 of 0.9941. The r2 value for vitamin D3 was not very accurate which was due to carry over during the calibration analysis, but both calibration curves were very reproducible with % RSD of less than 5%. The % recoveries calculated after the extraction was found to be 149.6 % for vitamin D3 and 111.1% for vitamin E, but the % recovery obtained for vitamin D3 was above the recommended range which was due to co-elution with other vitamins and ingredients.
