[PDF] acid hydrolysis of fats and oils

Hydrolysis of oils and fats is the applied term to the operation in which ethanolic KOH reacts with oil to form glycerol and fatty acids (FAs). Production of FAs and glycerol from oils are important especially in oleochemical industries.

  • Answer: This method is used to measure crude fat by acid hydrolysis. The fat is released with hydrochloric acid and is extracted with ethyl ether and hexane. It is then filtered, dried, and gravimetrically measured. This method is used for a variety of foods.
