The container for cultivating yacon can't be metal, it's all made of glass and ceramics, and it's a special plastic product for microwave ovens. The container should be clean, not damp, smelly or spicy, and should not be stored in bookcases and places where it is too cold and overheated.

Pour fresh milk into a container full of yacon, at least without touching yacon. Ferment at the temperature of 18-25 degrees for about 12 hours, and you can filter out the yogurt and put it in a small basket to drink. The bacteria in the box should be cleaned with cold boiled water and fermented in fresh milk.

10-30 days later, the yacon can be doubled, and more people can drink at this time.

1: After cleaning the bacteria, put a small amount of milk in a sealed container and store it in a refrigerator at 1-3 degrees. You can change milk once every half a month or so!

2. After the bacteria are cleaned, put a small amount of milk in a sealed container and store it in the refrigerator. You can change milk in about 2-3 months!

In the above environment, bacteria basically do not ferment, but bacteria are dormant and will not die!
