Manufacturing Quality Control of Fatty acids, C16-18 and C18-unsatd., Me esters

Detection Item Common Analytical Method Method Overview
Acid Value Acid-Base Titration Measures free fatty acids by titration with standardized KOH solution in alcoholic medium.
Iodine Value Wijs Method Quantifies unsaturation via addition of iodine monochloride to double bonds, followed by titration of unreacted iodine.
Saponification Value Acid-Base Titration Determines total ester content by alkaline hydrolysis and back-titration of excess KOH.
Ester Content Gas Chromatography (GC) Separates and quantifies methyl esters using a polar capillary column and flame ionization detection.
Free Glycerol Gas Chromatography (GC) Direct quantification of unreacted glycerol after derivatization or using specialized GC columns.
Moisture Content Karl Fischer Titration Electrochemical titration measuring water content based on iodine generation proportional to water.
Density Pycnometry Determines mass per unit volume at specified temperature using calibrated glass pycnometers.
Viscosity Capillary Viscometry Measures kinematic viscosity by timing flow of sample through a calibrated capillary tube under gravity.
Flash Point Pensky-Martens Closed Cup Determines lowest temperature at which vapors ignite in presence of flame under standardized closed-cup conditions.
Color ASTM D1500 Compares sample color visually or instrumentally against standardized iodine scale in 100-mm cells.
Sulfated Ash Gravimetric Analysis Measures inorganic residue after high-temperature combustion and subsequent weighing of ash.
Metals (Na, K, Ca, Mg) ICP-OES Quantifies trace metal concentrations by plasma excitation and emission spectral intensity measurement.
