Lecithins and mono and diglycerides of fatty acids are quantum satis status, most added into foods as stabilizers and emulsifiers.
Some parameters remain inadequate, such as diglycerides amount and insufficient conversion rate, but new investigation can be carried out in order to make better these parameters.
The specific JME fuel properties that include density at 15[degrees]C, calorific value, flash point, cetane value, specific gravity at 15[degrees]C, viscosity at 40[degrees]C, water content, ash content, acid value, monoglyceride, diglyceride, triglyceride, free glycerine, total ester content, and total glycerine contents were evaluated with a fuel property testing equipment built on the ASTM standards (D2624, D3828) and European standards (EN 14105) such as calorimeter, fuel test kit, and gas chromatograph (Shimadzu-GC-2010 Plus) fitted with a flame ionization detector FID2010 Plus and a capillary column of size 30 m x 0.25 mm x 0.25 [micro]m.
The presence of signals at 3.55 ppm, 3.66 ppm, and 5.30 ppm (central hydrogen atoms of the glycerol part) could be due to the presence of mono- and/or diglycerides which would be still present in the obtained product.
That is, conversion of triglycerides to diglycerides, followed by the conversion of diglycerides to monoglycerides.
However, majority of the lipases are capable of converting triglycerides, diglycerides, monoglycerides and free fatty acids to fatty acid ethyl esters in addition to fat hydrolysis (1,4).

The transesterifaction of triglyceride leads to mono- and diglycerides of lower molecular weight compared to triglycerides, and the resulting molecular weight is known to be inversely proportional to the glycerol content.
TP in fresh frying oil include sterols, tocopherols, mono- and diglycerides, free fatty acids, and other oil-soluble components that are more polar than triglycerides [30].
