What is Gerber method for milk?
The Gerber Method is a primary and historic chemical test to determine the fat content of substances, most commonly milk. The Gerber Method was developed and patented by Dr. Niklaus Gerber of Switzerland in 1891. In this method milk fat is separated from proteins by adding sulfuric acid (1.820-1.825 sp.
How is milk price calculated?

The Gerber method is used worldwide as a simple and rapid method for determining the fat in raw and processed milk.
What kind of CAD system does Gerber use?
Gerber Technology’s apparel CAD system,62,63 AccuMark APDS-3D, is a product acquired from Asahi Chemical Industry Co. Ltd. The system allows pattern makers to select patterns from AccuMark™ Pattern Design and instantly view them assembled on a 3D dress form. The garment can be modified to change the fit or even the design on the 3D form.
