About this document
AOCS Method Ca 12-55: Phosphorus Analysis by Luki Wahyuning Tiyas is a document available to read on EtoBox.
This document provides the procedure for determining the phosphorus or phosphatide content in commercial fats and oils using a spectrophotometric method. Key steps include ashing the oil sample with zinc oxide, dissolving the ash in acid, neutralizing and developing a blue color complex with reagents, and measuring absorbance to determine phosphorus content against a standard curve. The percentage of phosphorus can then be approximated as the percentage of equivalent phosphatides for soybean oil samples.
