Homemade yogurt, chemistry class!

The kitchen has a lot of chemistry and laboratory. Together with the children, we are going to put on a white coat and go into the kitchen-laboratory to learn how to make yogurt. You will see that with milk and a yogurt, and not by magic, more yogurt comes out. It is not a miracle, they are things of nature.

The secret is that if we feed the yogurt with hot milk, the bacteria in the yogurt produce fermentation. which transforms the sugars in milk into lactic acid. Thus the milk thickens and turns into yogurt.

Yogurt has been used since ancient times. It is believed that it was formed spontaneously by the
action of the sun's heat on the containers in which the milk was kept, which were made with the skins or stomachs of animals in which the bacteria that make up the yogurt are found.

Once made, without opening the bottle, the yogurt will keep for 8 or 10 days. Once opened, it is preferable to consume it in about 4 days.
