Starter cultures are the bacteria used to turn milk into yogurt. As the starter cultures (bacteria) start to grow, acid is produced which curdles, or thickens, the milk. Starter cultures also give the yogurt its flavor when it produces things compounds like lactic acid. There is also a probiotic effect from starter cultures as it can improve the health of your digestive system.

Why does the milk used to make yogurt need to be bacteria free?
The milk used to make yogurt does not have to be bacteria free, but it helps. The reason is that yogurt is made by adding good bacteria "Dairy yoghurt is produced using a culture of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus salivarius subsp. thermophilusbacteria" which means those cultures will be in competition with any other bacteria, good or bad, which may be present in the milk.For home yogurt making, it is recommended you heat milk to 190F before cooling it down and adding the culture - that kills any other bacteria present and changes the proteins in the milk to increase the firmness of the resulting yogurt.
How do you stop stomachaches?

What is the description of set yogurt?

If you freeze yogurt will the live active cultures still be good?
The live culture in the yogurt does not die when frozen, it becomes dormant instead. After you thaw or eat the yogurt, the dormant culture comes back to life.The amount of 'live culture' in commercially sold 'frozen yogurt' may only be a fraction of culture compared to regular yogurt. It has to do with the manufacturing process, and not the effect of temperature.The 'live culture' does die when the yogurt is heated. Heat treated or pasteurized yogurt have no live culture.I am from India. I always make Dahi (yogurt) at home. I whip and freeze a part of yogurt to start next batch. I thaw out the frozen yogurt in the refrigerator, whip it and use it as a starter for the next batch. When the yogurt is frozen, it does lose the texture. That's is the reason i whip the yogurt before freezing and after thawing.

When making a smoothie does it matter if you change plain yogurt to vanilla yogurt?
You can use vanilla yogurt, but realize that you are also adding sugar that is in the vanilla yogurt. So you might want to reduce the sweetener that you add to the smoothie. Also, consider whether the vanilla flavor is compatible with the other ingredients. It should go with most fruits.
In making yogurt why do you need to cool the milk to 50 degrees Celsius?
You have to cool the milk to 50 degrees celsius or less before adding the starter culture because otherwise all the microorganism you will use for fermentation will die and the fermentation won't take place. Most of the bacteria (Lactobacillus, usually) need 37 degrees celsius for growing and fermentation. Temperatures higher than their optimum temperature will decrease their grown and the fermentation process will be slow or can kill these bacteria.
