Estimate Fatty Acid Calculation
To estimate the free fatty acid in feed.
Weigh 20g of the feed and extract the oil from it using soxlet apparatus,then add 10ml of ethanol and mix properly,also add a drop of phenolpthalein and titre it against 0.143N sodium hydroxide.End point is the appearence of pale permanent pink colour.

Percentage of free fatty acid
percentage of free fatty acid = ( V * N * F /weight of sample )
V - Volume of sodium hydroxide
N - Normality of sodium hydroxide
F - Equivalent factor
This online calculator helps you dynamically to calculate the percentage of free fatty acid easily.
