Interference on MOSH MOAH readings when Food Grade lubricants are used?

04 March 2021 1 8K Report

What is the content of MOSH/MOAH in food grade lubricants? Does the use of food grade lubricants have an impact on the analysis results for MOSH/MOAH in refined edible oils?

We added several ppm of Food Grade lubricants into samples of crude oil. We were shocked at the results obtained when comparing oil without Food Grade lubricant, and that wijth small amounts added. WOuld this occur? If yes, why does it happen? Why would the MOAH levels rise?

Shyam Lakshmanan

Food Grade LUbricants contain greater than 90% MOSH and it may contain high levelos of MOAH too. Hence usage of FG lubricants is not the way to achieve low levels of MOSH and MOAH in rfefined oils.
