Stevia, also known as steviol glycosides, is an extract of stevia leaves. It contains no sugar and calories and is naturally low in calories. If you are not familiar with it, then it can be compared with Luo Han Guo. Everyone knows that Luo Han Guo has a rich sweetness when soaked in water, but it has no calories. Stevia is the same. And now all kinds of very red zero calorie fruity soda sparkling water also use stevia. However, in addition to sweetness, stevia does not have the other characteristics of sucrose. Therefore, in gourmet production, if it is purely a sweet substitute, stevia is a good choice.
