SV saponification value is correlated with the average chain length (molecular weight) of the fatty acids profile, IV the iodine value represents the oxidative stability by evaluating the total unsaturation of the fatty acid profile, CN the cetane number represents the ignition property, DU denotes the degree of unsaturation of the fatty acids which represents the oxidative stability during long term storage, LCSF a high long-chain saturation factor indicates an oil rich in LC-SFA and therefore more sensitive to crystallization, CFPP (°C) the cold filter plugging point is the temperature at which the biodiesel tends to crystallize which can clog the filters and fuel lines (Ruangsomboon 2015)
