Bacteria in Yogurt
Yogurt is made by boiling milk and adding special bacteria on it. Then, it is kept warm for several hours. The reason why it is kept warm for several hours is so that the bacteria multiplies and turns the sugar in the milk into acid. The acid makes the milk go thick and also stops the breeding of bacteria. Interesting, right? I had just know this and was very fascinated with this yogurt-making process so I wanted to tell all of you, my readers, about it. Did you know? The bacteria in the yogurt is good for our digestive system!
Yeast in Bread
A microorganism that is already well-known as is used in many bakeries called 'yeast' is added to the dough to help the bread rise. The yeast turns the sugar in the dough into carbon-dioxide. As the dough is heated, the bubbles carbon-dioxide get bigger and then the bread rises. I know that yeast helps to make the dough rise before, but I have never known why and how it rises! Very interesting!
Uncooked food
Uncooked food (especially meat) sometimes contain bacteria that is called, 'Salmonella'. Salmonella is not good for us, but usually, this bacteria will be killed after being cooked. If you eat food that has not cooked properly, the 'Salmonella' may survive and cause your gut to multiply and make you very ill if you eat it. Better be careful! Always take care of your health so that you can keep on reading my posts on this blog. :)
