How do you make the delicious vanilla flavor?

 In fact, the "vanilla" flavor we eat is related to a kind of edible spice vanillin
.
Vanillin, also known as vanillin, has a slightly sweet taste and a slight milky fragrance.
It originally comes from a Rutaceae plant called vanilla bean
.
 However, the extraction steps of natural vanillin are cumbersome, low in content, and expensive, so synthetic vanillin is now used
.
It is precisely because of the wide application of synthetic vanillin that vanilla flavor has become one of the common flavors of foods such as ice cream, cakes, and candies
.
 China is one of the main countries producing vanillin in the world
.
Because vanillin is relatively safe, vanillin can be used in the second and third infant milk powders and some cereal supplements for infants and young children in China.
The maximum usage amount is 5mg/100ml and 7mg/100g, but pay attention to 0- It is not allowed to be added to infant formula for a period of 6 months
