Application

Beer industry: Used to absorb tannins and other substances that cause turbidity, ensuring that beer remains clear and transparent during storage.

Winemaking: Removes polyphenolic compounds that may cause precipitation and prolongs the stability of the wine.

Juice processing: Improves the clarity of juice and reduces turbidity and precipitation.

Functional beverages: Used as an emulsifier or suspending agent in the formula to ensure that the ingredients are evenly distributed.

FAQ

1.What is the difference between food-grade PVPP and industrial-grade PVPP?
Food-grade PVPP: After strict purification and testing, it meets the safety standards of food additives and can be directly used in food and beverage processing.
Industrial-grade PVPP: It is used in non-food fields (such as coatings, adhesives, etc.) and contains impurities that may be harmful to the human body.

2. Does food-grade PVPP affect the flavor of food or beverages?
No. It does not participate in the chemical reaction of food. During use, it only adsorbs impurities and does not change the taste, color or texture of the product.

3. Can food-grade PVPP be reused?
It can be reused by simple cleaning and regeneration treatment when clarifying beverages. The number of reuses depends on the processing conditions and the use environment.

4. What are the storage conditions for food-grade PVPP?
It should be stored in a dry and cool environment, avoiding direct sunlight and high temperature.
It needs to be sealed after opening to prevent moisture from affecting its performance.

5. Does food-grade PVPP have any impact on the environment?
The chemical properties are stable and non-toxic to the environment.
