Products Description
POLYVINYLPOLYPYRROLIDONE
Description: PVP-P behaves as a white or creamy white powder with faint characteristic odor, which is easily hydrophilic and capable of complex with such substance as phenol, etc. It is completely insoluble with relatively high crosslink density and does not form gels that can impede disintegration, dissolution and drug release. It was accepted into Ph Eur 5.0 and USP/NF28th.
CTFA Nomenclature : POLYVINYLPOLYPYRROLIDONE ( Abbreviated to be PVP-P)
CAS No. : 25249-54-1
Packaging : 20 kg/fibre drum
Specification :
1,Beverage industry:
PVP-P can be used in
-Improving the quality and extends the shelf-life of beer by absorbing the polyphenyls and tannoids.
- Prevention of 'pinking' and 'browning' reactions in white and sparkling wines
- Enhanced aroma and flavor in red wines
PVP-P is a cost-effective and safe treatment in beer industry that
- Completely insoluble in beer
- Applicable to all types of beer
- Higher efficacy - lower dosage
- Easy to use and excellent handling characteristics
- Insoluble process aids, with wide regulatory approval
- No negative impact on foam, flavor or other quality parameters
- Improved dispersion and sedimentation characteristics
- Longer filter run lengths compared to silica alone
- Uses existing plant equipment
2,Pharmaceutical Industry : Provide rapid disintegration in a wide range of oral solid dosage formulations and processes. Especially in the following areas:
- In wet granulation tablet processes.
- Ideally suited for use with poorly compressible drug actives and in direct compression tablet processes.
- Outstanding performance in manufacturing ionic, acidic and alkaline drug actives
- Quick dissolve and chewable tablets
- Treat gastrointestinal disorders and as an anti-diarrhea agent.
Furthermore, PVP-P can also be used to improve solubility, and hence, enhance bioavailability in not only human but also veterinary applications
Application: used as stabilizer in beer, wine, tea beverage, juice & other beverage industry.

PVPP stabilizer for beer
Introduction
Even through the beer are filtrated,stored some time later, the turbidity & sedimentation will be formed also, then the shelf-life will not be long. This phenomenon mainly caused by the polyphenols in the beer, such polyphenols have a particularly high haze-forming potential which will be caused the beer cloudy. can avoid premature turbidity by the removal of polyphenols brings clear appearance & advantages in taste, also prolongs the shelf-life.
Mechanism of Haze Development
Fresh beer contains simple flavanoid polyphenols and kind of proteins, such polyphenols and proteins are easy to form weak hydrogen bonds, thereby form some compounds, and these compounds are invisible due to their low molecular weight.. 3 to 6 weeks later, the flavanoids oxidized and polymerized, and every 3-4 bonds formed one new unit substance-called "tannoids". Tannoids can produce visible colloidal particles by naked eyes. The effect of hydrogen bonds which connect the polyphenols together are weak, when the temperature rise they are broken, then the turbidity disappeared. We call this "chill Haze".
After a longer storage period, ionic and covalent bonds formed between the flavanoids and the proteins. They are stronger that can not be broken by an increasing temperature, so permanent haze would develop in beer.
PVPP stabilizer for beer
Safe to use
is dissoluble in water,so can be removed though filter.
PVPP used as beer clarifying agent was applied in food field in 1973,and registered in Gerengy. The relatied laws and regulations can be found in current edition of food chemistry index, EU rules, Japan Register authority, and food and drug union regulation index. These systems also can be applied in supervise the application of PVPP in other beverage industries.
Single-use process
Preparing 5-15% suspension with deoxidation water, continue to stirring mor than 60 minutes, making particles with beer to contact sufficiently. is added uniformly accompanied by the process of kieselgur added continuously
Adsorption time & dosage
A few minutes of adsorption can get obvious effect.But in order to give full play to the effect, it's recommended that the adsorption time more better lasts 10 minutes.it can't influence on beer if extending the adsorption time.The dosage of is controlled in the range of 10-45g/hl.
Recycling process
Preparing 10% suspension with deaerated water in dosing vessel, continue to stir. After the beer filtered by kieselgur, suspension is uniformly added to the beer filtration through measurement .
Adsorption time & dosage
At least more than three minutes of the adsorption time can get obvious effect. Dosage is controlled in the range of 20 to 50 g/hl
Regeneration
Regeneration function--under alkaline condition, the hydrogen bond can open, polyphenols are dissolved clean, is regenerated..
Wastage
Each regeneration process loss about 0.5 to 1%. Suggested that the concentration of suspension should be checked at regular intervals, and adjusted properly
