    The fat content of a milk product is an important indication of quality, both economically and physiologically. In the dairy industry, it is mainly determined by using ‘'quick methods'’. Spectrometric measuring methods are often used. However, these methods have to be calibrated, which is costly. milk Mid-infrared spectroscopic method milk Automated turbidimetric method milk Automated turbidimetric method Raw milk Rapid detergent method Raw, whole milk Gerber method Raw milk Babcock method Cream Babcock method Wash sample with ether or petroleum ether, fat = – water -residue File Size: KB.

James. The traditional standard reference method for fat analysis is based on either weight or volumetric determination. There are many analytical methods for the determination of the fat content of milk; the Gerber test is widely used all over the world.

Principle. The test is a volumetric method in which fat is separatedfrom milk by centrifugal force. Photometric Milk Fat Determination. Journal of Dairy Science42 (8), DOI: /jds.S(59)Cited by: 4.

Objective: To determine the fat content in milk and dairy products by milk-fat analyzer, and to compare with national standard method. Methods: Based on the third method of the national standard GBsamples were hydrolyzed by alkali on-line method, then the hydrolysate of the sample was extracted by anhydrous ethyl ether and petroleum : Chen JianYong, Jiang XiuMin, Huang LiJun, Jing HuiPing, Mi XiaoLi.

Relative standard deviations increased with decreasing fat content, and were summarized by fat level: % fat milk, mean =RSD(r) = %, RSD(R) = %; % fat milk, mean =RSD(r) = %, RSD(R) = %.Cited by:   Fat determination in milk Procedure: Take 20 ml of milk in a beaker.

Fat content is determined often by solvent extraction methods (e.g., Soxhlet, Goldfish, Mojonnier), but it also can be determined by nonsolvent wet extraction methods (e.g., Babcock, Gerber), and by instrumental methods that rely on the physical and chemical properties of lipids (e.g., infrared, density, X-ray absorption).Cited by:.
