Cape hake protein hydrolysates prepared from alkaline solubilised proteins pre-treated with citric acid and calcium ions: Functional properties and ACE inhibitory activity

- Hydrolysates with pre-treatment of citric acid and calcium ions were prepared.
- Pre-treatment allowed a reduction in phospholipids content of hydrolysates.
- Hydrolysates had good functional properties and exhibited ACE inhibitory activity.
- Hydrolysates can be a potential food ingredient or a natural dietary supplement.
