CONDENSED MILK AND MILK POWDER 401 



WHAT DOES 



THREE FUNDAMENTAL PRINCIPLES 



The different uses for BK are based on three funda- 

 mental principles. When these are understood it gives 

 an appreciation of BK and a knowledge that enables man- 

 ufacturers and handlers of dairy products to apply it in 

 many ways to lighten labor and produce purer products. 



These principles are: 



1. High bacteriacidal power 



2. Solvent Action 



3. Harmlessness 



The bacteria-destroying power of BK is high, so that 

 it kills the bacteria on coming in contact with them. 



The solvent action of BK on albumins milk casein, 

 etc., softens the accumulations on coils, heaters, pasteur- 

 izers, pipes, etc., making the cleaning operation easier. 

 Where the metal parts of equipment are not already 

 coated with casein the application of BK before the daily 

 run prevents a milk film from adhering and also dissolves 

 any thin albuminous film that might be there. This sol- 

 vent action also exposes the bacteria to prompt destruc- 

 tion. 



These two functions of BK insure a high degree of 

 sterilization and cleansing also great economy of labor. 



BK is a harmless hypochlorite such as used by the 

 most experienced medical men in and on the human body 

 adopted by the great surgeons of the allied armies 

 after trying over 150 different articles for protection of 

 health and foods of the armies. 



The amount of BK needed to make an effective steril- 

 izing solution is very small and the amount of BK left on 

 the equipment after using is infinitesimal and negligible. 

 Authoritative Experiment Station bulletins prove this 

 point conclusively in their tests on chemical sterilizing. 



BK is easy to use everywhere for purifying, deodoriz- 

 ing and disinfecting. BK has stood the test of time it 

 has made good. Those who learn its helpfulness become 

 constant users.
