Method Description:
The sample is saponified to digest lipids and convert tocopherols to their alcohol forms. HPLC with a flourescence detector is used to analyze the extractant.
Information Required by Submitter:
Please supply estimates of tocopherol levels. If this information is not available, please indicate the food type. If this is a concentrated sample, please note this on the analysis request form.
Additional Information:
Tocopherols are very sensitive to oxidation. Be sure the sample is submitted in an airtight container that is filled completely, if possible. If headspace is present in the container, flushing with nitrogen reduces oxidation. Shipping and handling at reduced temperatures helps maintain the integrity of the sample.
