Why do we use acid for fat in milk?
The test is a volumetric method in which fat is separatedfrom milk by centrifugal force. Sulphuric acid is used to dissolve the protein that forms the membrane around the fat (fat globules) and amyl alcohol is added to improve the separation of fat from other solids.
What is the mojonnier method?
Mojonnier method Is a gravimetric method that uses organic solvents to extract fat. Subsequently the solvent is evaporated and the fat is determined by weighing the dry fatty extract. Then the fat content is measured in a special flask (butyrometer).
What is the purpose of using 90% H2SO4 in Gerber method?
In this test H2SO4 is used to increase specific gravity of milk serum which makes greater difference between milk serum and fat globules. It also destroys stickiness of milk by dissolving all the SNF.
How do you extract fat from cheese?
Place a cellulose filter into an 11-mL extraction cell before loading the sample. Finely grate the sample cheese. Weigh out 1 g of the grated cheese and grind with 2 g of ASE Prep DE using a mortar and pestle. Grind thoroughly and completely, as this can affect the fat recovery.
