Show Bacteria in Milk Before bacteria can they must have warmth and If all of these are furnished the development will be very In milk there is an abundance of food and moisture and the usual temperature will promote the rapid formation of The food elements needed by the bacteria are contained in ideal amounts and proper state in the the only way the dairyman can hinder the production of bacteria is by regulating the temperature so that the formation will be greatly Bacteria will thrive in a wide range of Some species will thrive when the temperature is while other species seem to multiply more rapidly when the temperature is at about 90 degrees most forms develop very while at 55 degrees the development is only about one twenty-fifth as Several experiments show that there is as great a difference between these two temperatures as bacteria per cubic At a temperature of 50 degrees they remain inactive and if the milk is kept at this their development will be so slow that the milk can be kept for a considerable length of time without On the other if the milk is warmed to a heat of from to nearly all of the forms of bacteria are Perhaps the best way to hinder the formation of bacteria in is to cool it as quickly as possible in order to remove the animal heat after it has been drawn from the Then heat it to a temperature of degrees or even to the boiling after which it should be put in sealed tightly and set away in a place where the temperature is about 50 Leave it there till you are ready to use Milk treated in this way will remain sweet for several |
