THE ALCOHOL TEST IN RELATION TO MILK. 



23 



tests, together with their acidity and bacterial counts. We wish to 

 call particular attention to the bacterial counts of 142 samples of 

 raw milk which ranged from 2,000 to 19,600,000 bacteria per cubic 

 centimeter. Of these 142 samples none gave a positive alcohol test, 

 yet 86, or 60.6 per cent, contained less than and 39.4 per cent more 

 than 500,000 bacteria per cubic centimeter. 



The bacterial counts of the samples of pasteurized milk which gave 

 a negative alcohol test ranged from 1,200 to 3,600,000 per cubic 

 centimeter, as may be seen from Table 19. 



From our results we believe that there is no definite relation between 

 the alcohol test and the bacterial count, except in special cases where 

 the bacteria have developed to a point where there is sufficient acid 

 produced or where rennet-forming bacteria have acted sufficiently 

 to influence the test.

 alcohol tests with 75 per cent, 68 per cent, and 44 per cent alcohol.
