Application

Beverage clarification: One of the most widely used applications of PVPP is as a beverage clarifier, especially in the production process of beverages such as wine, beer, and juice.

Wine: PVPP is used to remove polyphenolic compounds in wine, especially to remove substances that may cause bitterness and astringency during the production process.
Beer: In beer production, PVPP can remove phenolic substances and impurities in beer, prevent beer from becoming turbid during storage, and ensure that the beer is clear and transparent.
Juice: PVPP is used for clarification in juice to remove pulp particles, phenols and impurities in juice, making the juice taste fresher and clearer in appearance.

FAQ

1.What is the main role of PVPP in food?
It is used in the clarification process of food and beverages. It helps improve the transparency, stability and taste of beverages by adsorbing impurities, pigments and phenolic substances.

2. How does PVPP work in beverages?
It removes phenolic substances, pigments and impurities in beverages by physical adsorption.

3. Is PVPP harmful to the human body?
The use of PVPP in food is safe and complies with the relevant regulations on food additives.

4. Is there a regulation on the amount of PVPP used in food?
Yes, there are strict regulations on the amount of PVPP used. Depending on the type of food and beverage, the amount of PVPP added should be controlled within the prescribed range.

5. Does PVPP affect the taste of food?
Since PVPP removes impurities by physical adsorption and does not chemically react with other ingredients in food, it does not change the taste of food.
