- Polenske value
The Polenske value (also known as the Polenske number) is a value determined when examining
fat. The Polenske value is an indicator of how much volatile fatty acidcan be extracted from fat through saponification. It is equal to the number of mililiters of 0.1 normal hydroxidesolution necessary for the neutralization of the water-insoluble volatile fatty acids distilled and filtered from 5 grams of a given saponified fat. (The hydroxide solution used in such a titrationis typically made from sodium hydroxide, potassium hydroxide, or barium hydroxide.) [ Food and Agriculture Organizationand World Health Organization.
