1, containers for cultivating Yacon should not be made of metal, but all of them should be made of glass and porcelain. The containers should be clean, not wet, smelly or spicy, and should not be stored in bookcases or places that are too cold or too hot.

2. Dip two tablespoons and a half of yacon into fresh milk for 24 hours.

3. Pour the yacon soaked with milk into the filter screen, and the milk is filtered into the container through the filter screen, then rinse the yacon in the filter screen with cold boiled water, then add half a catty of fresh milk to soak it, and cover it with a layer of gauze to prevent dust.

4, Yacon milk is best to drink before going to bed. During this period, any milk products are not drinkable. During the period of stopping drinking Yacon milk, Yacon filtered, washed and replaced fresh milk as usual.

5. Yacon should be placed in a ventilated room. Not sealable. Do not put it in the refrigerator.

6. Yacon provides sour milk (honey can be added for those who are really uncomfortable, but no sugar can be added).

7. Yacon should not touch iron and metal (except acid-resistant metals such as stainless steel), and it is best to use porcelain or glassware.

After 8 or 28 days, Yacon will increase to double its volume and can be sold to people in need.
