Stability
Maximum stability and protein extractability occur within pH 5.5-6.0. As a hygroscopic powder, it requires storage below 5% moisture to prevent microbial growth.
Conflicts
- Strongly alkaline environments (pH > 8.0) can cause alkaloid precipitation.
- High tannin content may interact with gelatin or high-protein bases due to astringency.
