The acid value of oil indicates the amount of free fatty acids present, which can impact the oil's quality by affecting its flavor, shelf life, and stability. Higher acid values can lead to rancidity, off-flavors, and decreased stability of the oil. Therefore, oils with lower acid values are generally considered to be of higher quality.

Why is acid value important?
" acid value (or "neutralization number" or "acid number" or "acidity") is the mass of potassium hydroxide (KOH) in milligrams that is required to neutralize one gram of chemical substance."-wikipediaOils are made of triglycerides. During processing some amount of oil can be break down to fatty acids and glycerol s.This amount of fatty acids should be less.Every oil has a specific acid value range. It shows the amount of free acids available in oil.So it is used as a Quality parameter of oil.as a example acid value of coconut oil should be below 3mg. otherwise its consider as a poor in quality
How much citric acid does lemon essential oil contain?
Lemon essential oil typically contains around 2-4% citric acid. However, the exact percentage can vary depending on factors such as the extraction process used and the quality of the oil.
How do you produce soybean acid oil from soap stock?
Soybean acid oil can be produced from soap stock by hydrolyzing the soap stock with an acid such as sulfuric acid. This process breaks down the esters in the soap stock, releasing free fatty acids which can then be separated and neutralized to form the soybean acid oil. The final oil product can be refined further to improve its quality for various industrial uses.
What is the Saponification value of Glycerin?
Glycerin and soap are the bye-products of saponification. The saponification value of glycerine are values of the percentage of lye it takes to convert one unit of fat, oil or fatty acid into glycerin.
