CONDENSED MILK DEFECTS, THEIR CAUSES 

 AND PREVENTIONS 



CHAPTER XXII. 



CLASSIFICATION OF DEFECTS. 



Many are the defects which cause condensed milk to be 

 rejected on the market and numerous are the avenues that may 

 lead to the manufacture of defective milk. The milk faults may 

 be of mechanical, physical, chemical, or bacteriological origin, or 

 they may be due to a combination of two or more of these forces. 

 In some instances the defects can be detected in milk during; or 

 immediately after the process, in which case they may be rem- 

 edied, or their recurrence prevented. But more often, several 

 weeks may pass before abnormalities develop and before the 

 manufacturer realizes that something is wrong with the milk. 

 In the meantime, the conditions which originally produced the 

 milk defect may have so changed, that it is exceedingly difficult 

 to locate the seat of the original trouble.
