Food-Grade Protease (Proline Protease) — Liquid Brewing Additive
本产品是一款 food-grade protease developed specifically for the beer brewing industry. It is widely used as a liquid enzymatic additive to support beer clarity, cold stability, and overall visual quality during production and storage. By selectively acting on haze-forming proteins, it helps reduce the risk of chill haze without altering the beer’s original flavor profile.
Designed for professional brewing applications, this protease integrates easily into standard brewing processes and supports consistent product performance across different beer styles and process conditions.
主要优势
- Helps prevent the formation of chill haze in beer
- Does not affect beer foam stability or beer flavor
- No oxygen introduction risk during application
- Helps preserve the beer’s potential natural antioxidant capacity
建议用量
5–200 g per metric ton of raw materials
The optimal dosage depends on beer type, raw material composition, processing conditions, and desired clarity or stability outcomes. Pilot trials are recommended to determine the most effective application level.
应用领域
- Beer brewing applications
- Chill haze prevention and stability improvement
- Process support for finished beer clarity
Function in Brewing
During beer production, certain protein fractions can lead to chill haze when the beer is exposed to low temperatures. This protease works by breaking down haze-forming proteins into smaller, more soluble fragments, helping maintain a bright and stable appearance during cold storage and distribution. The enzymatic action is controlled and targeted, ensuring no negative impact on sensory attributes.
