Product Uses
As a stabilizer for beer, liquor, grape juice and fruit juice and other beverages, extend its storage period.
It can form hydrogen bond complex precipitation with phenols such as anthocyanins and flavonoid polyhydroxyl derivatives through carbonyl groups, thereby removing the non-biological turbidity of alcohol, achieving clarification and stability, and maintaining the original taste and flavor of the beverage.
It is completely insoluble in beer (red wine, juice, etc.) and suitable for any kind of beer (red wine, juice, etc.), improves color and taste, and has no adverse effect on foam and flavor, and can extend its shelf life.
It can also be used in combination with enzymes (proteases) and protein adsorbents to remove allergens.
Product Operate Guide
The PVPP is prefabricated into 8-12% slurry with deoxidized water, and it is left for about 1 hour to make the particles of PVPP fully absorb water and spread out, improve the adsorption efficiency, mix it alone or with other additives such as diatomaceous earth and add it to beer, and fully contact for more than 5-10 minutes after the adsorption is completed, the beer can be completely removed from the PVPP in the body.
