ELECTRICAL AND ULTRA-VIOLET-RAY TREATMENT OF MILK 
Many attempts to kill bacteria in milk by means of electricity have 
been made, but no such process has been devised which has come into 
extensive commercial use. 
Alternating currents have been worked with most extensively, be- 
cause direct currents were found to produce undesirable chemical 
changes in milk. Although the proper application of suitable alter- 
nating currents has resulted in bacterial reductions similar to those 
produced by pasteurization, it appears to be an open question whether 
the bactericidal action is due to the heat generated or to the direct 
action of electricitv on the bacterial cells.
