Part of it is probably due to the bacterial fermentation: acid is produced, which clots the milk just like if you let it go sour.
The proteins start clinging to each other and also absorb more water.
However, I find commercial yogurt is also heated, further denaturing the proteins and making the product more thick than home-made yogurt ever gets.
The thickness of yogurt is largely due to moisture; most recipes call for straining the yogurt in a cloth to remove excess water which makes it more viscous. It may be that Stonyfield Farm makes their yogurt with less water than most. Powdered milk can also be used thicken yogurt.
Bacteria has got in in to it and has curdled it.
If you look at the yogurt, you'll notice that it's thicker. When you add something thick to something light, it will get thicker.
Milk has a yogurt culture added to it, and is kept at the correct temperature for the bacteria of the culture to grow. The milk is converted to yogurt. You can then add any flavorings or additions you like.
Yogurt converts the milk sugar to lactic acid, driving the pH down. The low pH causes the milk proteins to coagulate into a soft curd. So basically yogurt is milk transformed by harmless bacteria.
The antibiotics prevent the growth of the bacteria that is needed to make the milk become yogurt.
to make it yogurt
No, just fruit, ice, yogurt, and maybe milk
Techically speaking, 3. ;-) If you are looking for substituting the milk with yogurt, you need to remember the consistancy of yogurt is quite a lot thicker than milk. I would suggest you use 3/4 cups of yogurt and add water to 1 cup. See if that is still the same consistency of milk. Ratio 3:4. I substituted yogurt equally to milk one time, and had to add water to the mixture. It does create a different texture than what milk would be. Very good flavour though.
Yes, it should be just fine to do so. But you need to use 'regular' yogurt instead of the thicker types of yogurt, such as Greek yogurt. Otherwise, the filling for the pie will be too dense and dry.
Depending on the yogurt their can be about 8 to 10% of milk in it.
The main substance used to make yogurt is milk. Many companies add sugar and flavoring such as fruit or vanilla.
add milk
Cheese and yoghurt are 2 different products that can be processed from milk. Cheese is made by the acid coagultion of milk while yoghurt is made by culture specific fermention of milk! In yoghurt lactic acid se formed due to fermentation! Which have many positive effects on body. While cheese is rich in proteins!
heat milk to make sterile, add milk proteins and stir well, add a starter culture of lactobacillus bacteria which ferments lactose (a sugar found in milk) in to lactic acid. This acid lowers the pH of the milk making it acidic. the milk proteins solidify (coagulate). you have now produced raw yogurt which you can add fruit and flavourings to.
