Product Description

Acid Protease AFP-530 is produced from Aspergillus niger through submerged fermentation and extraction and refining processes. It can be used as an alternative to a chemical de-foaming agent for the alcohol production.

Excessive foaming during the fermentation process in alcohol production is undesirable because it may slow down the fermentation. The foams generated from this stage usually come from the proteins contained in the raw materials. The protease enzyme is capable of hydrolyzing proteins, thus changing the foam structure by breaking down the proteins and making it lighter and less dense. It does not remove the foam, but prevents it from forming in the first place, thus enabling better fermentation control.

Packaging, Storage & Shelf-life

• 30kg plastic containers or 1125kg IBC totes. Customized packaging is available upon request.
• AFP-530 has been formulated for optimal stability. Typical shelf-life is 12 months provided being stored at 0∼25°C in its original packaging, sealed and unopened, protected from the sunlight. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement.

Safety & Enzyme Handling
Inhalation of enzyme dust and mists should be avoided. In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the appropriate Safety Data Sheet.
