To make yogurt from boiled milk, you need to add a yogurt starter culture, which contains live active bacteria. Typically, this can be plain yogurt with live cultures or a commercial yogurt starter. After boiling and cooling the milk to about 110°F (43°C), mix in a small amount of the starter culture, then cover and let it incubate in a warm place for several hours until it thickens.
The antibiotics prevent the growth of the bacteria that is needed to make the milk become yogurt.
No, just fruit, ice, yogurt, and maybe milk
to make it yogurt
Yes, you can make your own yogurt at home using milk and a yogurt starter culture. Simply heat the milk, add the culture, and allow it to ferment at a warm temperature for several hours. Once the yogurt has set, refrigerate it before consuming.
The main substance used to make yogurt is milk. Many companies add sugar and flavoring such as fruit or vanilla.
You can substitute yogurt for milk in a recipe by using an equal amount of yogurt as the amount of milk called for. This can help add creaminess and tanginess to the dish.
To make drinkable yogurt at home, mix plain yogurt with milk or water until you reach your desired consistency. You can also add sweeteners or flavorings if desired. Refrigerate before serving.
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.
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.
milkshakes, cheese, yogurt, pudding but maybe milk alone doesn't make anything but milk, you have to add something else to it.
If you add yogurt culture to heated milk before it has been cooled down to the appropriate temperature (usually around 110°F or 43°C), the high heat will kill the live bacteria in the culture. This prevents fermentation from occurring, meaning the milk will not thicken or develop the tangy flavor characteristic of yogurt. To successfully make yogurt, it's essential to cool the milk after heating it to the correct temperature before adding the yogurt culture.
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.
