Characteristics

Insolubility: PVPP is a cross-linked polymer that is insoluble in water and organic solvents. It can be easily removed by filtration or centrifugation after use.
High Adsorption: PVPP can adsorb tannins and polyphenol compounds in beverages through hydrogen bonds, which can cause turbidity and precipitation in beverages.
Chemical Inertness: PVPP does not react chemically with ingredients in food and does not change the taste, color and texture of food.
Thermal Stability: PVPP remains stable in high temperature environments and is suitable for a variety of processing conditions.

Application

Beverage Clarification

Beer: Adsorbs tannins and polyphenols that cause turbidity, keeping beer clear and stable.
Wine: Removes polyphenols that may cause precipitation and extends the shelf life of wine.
Juice: Reduces turbidity and improves the appearance quality of juice.

Beverage Stabilization

By adsorbing polyphenols that may cause oxidation and deterioration, food-grade PVPP can extend the shelf life of beverages while maintaining the flavor and color of beverages.

Antioxidant

Removes oxidation-initiating substances to prevent beverages and foods from changing color or taste due to oxidation.

FAQ

1.How to use food-grade PVPP?
It is usually added to food or beverages in the form of powder or granules, and removed by filtration or centrifugation after full contact with the liquid.

2. What are the advantages of PVPP in clarifying beer and wine?
Rapid clarification: effectively remove tannins and polyphenols, improve transparency.
Improve stability: extend the shelf life of the product and prevent turbidity or precipitation in the later stage.

3. Will the use of PVPP change the composition of food or beverages?
No. PVPP is a chemically inert substance that only adsorbs impurities and does not change the main ingredients, flavor or color of food and beverages.

4. Will food-grade PVPP cause pollution to the environment?
It has little impact on the environment. Used PVPP can be recycled or properly disposed of to reduce resource waste and environmental pressure.

5. Is PVPP suitable for use in highly acidic or high temperature environments?
Good thermal stability and acid-base tolerance can maintain stable performance under highly acidic (such as wine) or high temperature conditions.
