FAQ

1.What is the role of PVPP in food and beverages?
It is mainly used as a clarifier in beverages such as beer and wine. It can effectively remove tannins and polyphenols and prevent turbidity and precipitation of beverages.

2. Is PVPP edible?
Although PVPP is widely used in food and beverages as a clarifier, it is insoluble by itself and therefore will not be absorbed by the human body, but will be excreted through the digestive tract.

3. What is the role of PVPP in medicine?
In the pharmaceutical field, it is usually used as a disintegrant for tablets and capsules to help drugs disperse and be absorbed faster in the body.

4. Is PVPP harmful to the human body?
PVPP is considered a safe substance. It is not absorbed by the human body, but is naturally excreted through the digestive tract, so it does not affect health.

5. What ingredients can PVPP be used with?
In the food industry, PVPP is often used with other clarifiers such as silicon dioxide or gelatin to enhance the clarification effect.
