Sodium Citrate Dihydrate is highly concentrated — always start small and build up. Dissolving in warm water before adding to your mixture gives the most even, consistent colour.
| Application | Usage level | Purpose |
|---|---|---|
| Processed cheese / cheese sauce | 2 – 3% | Emulsification, smooth melt |
| Beverages / sports drinks | 0.1 – 0.5% | pH buffering, mild flavour |
