Heating milk before culturing denatures one of the main whey proteins, lactoglobulin, which allows it to join in the mesh (instead of remaining inactive) and effectively increases the amount of protein in the milk that will be available to thicken the yogurt.
What happens if you don’t boil milk before making yogurt?
7 Answers. Show activity on this post. The biggest reason to heat milk to almost boiling before fermenting is that it improves the texture of the yogurt. During fermentation the bacteria consume lactose and produce lactic acid which causes the milk proteins to denature and coagulate trapping most of the fat.
Why do we need to boil milk to make yogurt?
While yogurt can be made from room-temperature milk, for the best, most consistent results, most experts recommend first heating the milk to at least 180°F or the boiling point. Heating the milk makes for a richer end product, and also kills any bad bacteria in the milk.
Why do you boil the milk before adding the starting culture?

Do I have to heat raw milk to make yogurt?
NO NEED TO HEAT THE MILK IF ITS RAW
Raw milk yogurt is full of beneficial enzymes that will be destroyed if the milk is heated above 110° Fahrenheit (about 43° Celsius). According to Natasha Campbell McBride, founder of the GAPS diet, if you don’t heat the milk the innate bacteria of the raw milk are preserved.

Why do you have to heat milk to 180 to make yogurt?
Pour milk of choice into a double boiler and heat to 180°F. This will kill competing bacteria, and the whey proteins will denature and coagulate to enhance the viscosity and texture of the final product. Maintain temperature for 10 minutes for thinner yogurt, 20 minutes for thicker yogurt.
Why is my homemade yogurt not sour?
Why is my yogurt too sour or not sour enough? A. Culturing temperatures on the higher end of the range and longer culture times will yield a more sour flavored yogurt. To achieve a less sour flavor, culture at the lower end of the range or for a shorter period of time.

Why must you heat the milk before making yogurt What do you think would happen if you added the starter culture before the milk was cooled to 32 C?
