What can be inferred from saponification value of ester oil? It is well known that saponification number is related to the MW of fatty acid but the fact of existing unsaponifiable matters hinders the conclusion. Generally, I am wondering can we find any clue about the alcohols and acids making up the ester from saponification or even ester value of an ester oil?

The Ester Value is the number of mg of potassium hydroxide required to saponify the esters in 1.0 g of the substance. If the Saponification Value and the Acid Value have been determined, the difference between these two represents the Ester Value, i.e., Ester Value = Saponification Value – Acid Value.
Dear Dr Abdollah Golchoubi . Saponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) required to saponify one gram of fat under the conditions specified. It is a measure of the average molecular weight (or chain length) of all the fatty acids present in the sample as triglycerides.See the link: https://www.definitions.net/definition/saponification+value
The Ester Value is the number of milligrams of potassium hydroxide required to react with the esters in 1 g of a fat or oil.
Triglycerides (fats and oils) are important raw materials in the preparation of soaps.
Three measures of quality are the Acid Value, the Saponification Value, and the Ester Value.
#"Ester Value = Saponification Value - Acid Value"#
