Monitoring Soapstock Composition

BUCHI NIR-Online® sensors for monitoring soapstock composition: Oil Content, Moisture, Free Fatty Acids, Phospholipids and TFM Determination in Soapstock with NIR

Soapstock is obtained from the chemical refining process of crude vegetable oil. Rapid and accurate determination of soapstock composition is of critical importance to reduce neutral oil loss and thus to optimize the refining conditions and to improve the yield of the final product (edible oil). With the installation of a BUCHI NIR-Online® process analyzer after the alkali neutralisation step, the composition of soapstock is monitored and documented in a fast, simple, and reliable way. Within milli-seconds, several parameters such as FFA, oil content, moisture, Phospholipids, total fatty matter (TFM), acetone, insoluble material (AI), Loss of TFM from AI, OILTFM or AITFM are continuously, simultaneously, and accurately measured with NIR.
