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.
