Why do you need to heat milk to make homemade yogurt?!


Question: Why do you need to heat milk to make homemade yogurt!?
All the homemade yogurt recipes I have found online say one must heat milk up to 180 degrees, then cool it, before putting it into a yogurt machine!.

Why!? If I don't heat the milk, will I become ill if I eat the yogurt!? Or is it more a matter of the yogurt not thickening or setting properly!? In other words, is it more of a physical health issue to heat milk, or a recipe issue!?Www@FoodAQ@Com


Answers:
Kate if you are using raw milk it could be a physical health issue!. but if you are using
pasteurized milk it is a recipe issue!.
This the recipe I use [ Courtesy of Alton Brown!.]
1--quart 2%milk
1/2 cup powered milk
1 to 2 table spoons honey
1/2 cup plain un flavored yogurt [room temp!.]
Directions
Pour milk into a small sauce pan and whisk in powdered milk and honey!. Place over medium heat ,using a thermometer heat milk to120*F
upon reaching 120*F remove from heat pour into a cylindrical plastic container reserving 1/2 cup!.whisk in the reserved 1/2 cup into the yogurt
and add to the milk mixture!.[ferment for 3 to12 hours making sure the temp!.stays as close to 115*F as possable!. Kate I don't have a yogurt machine so I just wrap the plastic container in a heating pad set on medium and place in an old
ice cream maker bucket!. If using a yogurt machine I would think you would pour the mixture into the machine where I pour it into the plastic container!. I hope I have been of some help to you !. jim bWww@FoodAQ@Com
