Faster method than colorimetric determination of phosphorus contient in vegetable fats and oils?

03 April 2019 1 6K Report

Can anybody sugest other methods? They don't need to be standarts, we just need quantitative amount of phosphorus to change ratio for large amounts.

Hi!

I think, Phosphorus (P) is a mineral element. Therefore, you may consider sending your sample to a lab equipped with atomic absorption spectrophotometer (AA spec) or the ICP-MS. That may be easier for you than looking for alternative less sensitive method.

Otherwise, Colorimetric remain the simplest and among the oldest. I case you insist on have just an estimate of P content, then consider checking the food Tables which you can find in some nutrition books (e.g. Understanding Nutrition)! But how accurate will it be ?

How this guide a bit!

Best regards!
