Filtergel™ is used to clarify wine, beer and fruit juice. It's made from gelatin which is purified protein obtained by partial hydrolysis of collagenous raw materials. This product is usually supplied with 8-10, 20, 30, 40, 50 or 60 mesh particle size.
Potential Benefits
Foam stabilizer
Helps yeast growth
Improves the biostability of beer
Directions for Use
Soak the gelatin in cold water for 60 minutes so that the gelatin absorbs sufficient water.
Then water bathing it with 80°C water until it is fully melted.
It's NOT recommended to use boiling water for the melting procedure and please follow the principle of "Soak and melt just as much what you need".

Frequently Asked Questions (FAQ)
What is Filtergel™ and what is it used for?
Filtergel™ is a clarifying agent made from gelatin, which is a purified protein obtained by partial hydrolysis of collagenous raw materials. It is primarily used to clarify wine, beer, and fruit juices.
What particle sizes are available for Filtergel™?
Filtergel™ is usually supplied in various mesh particle sizes, including 8-10, 20, 30, 40, 50, or 60 mesh, allowing for flexible application based on processing needs.
How does Filtergel™ benefit beer production?
In beer brewing, Filtergel™ acts as an effective foam stabilizer, aids in yeast growth, and enhances the overall biostability of the finished beer.
What is the correct way to dissolve Filtergel™?
First, soak the gelatin in cold water for 60 minutes to allow it to absorb sufficient water. Then, heat it in a water bath at 80°C until it is fully melted. It is not recommended to use boiling water, and you should only prepare the amount needed for immediate use.
What are the heavy metal specifications for this product?
Filtergel™ complies with strict safety guidelines, with total heavy metals specified at ≤40 mg/kg. This includes limits of Arsenic ≤1 mg/kg, Chromium ≤2 mg/kg, Lead ≤1.5 mg/kg, and Zinc ≤30 mg/kg.
Are there microbiological control limits for Filtergel™?
Yes, it undergoes strict quality control: Aerobic Plate Count is limited to ≤1000 cfu/g, Coli Group is ≤3 MPN/g, and both Escherichia Coli (in 10g) and Salmonella (in 25g) must test negative.
