Drying Technology of Angiotensin Converting Enzyme Inhibitory Peptide Derived from Bovine Casein
Drying technology of angiotensin converting enzyme (ACE) inhibitory peptides derived from bovine casein was investigated. No significance was observed on ACE inhibitory activity of products prepared by spay drying and freeze drying (P>0.05). Spay drying was the best drying process for practical industry production. The inlet temperature ranged from 140℃ to 160℃ and the exit temperature ranged from 70℃ to 90℃ during the spay drying process. Under the optimal eonditious, scale-up of angiotensin converted enzyme inhibitory peptide from 1 L to 10 L and the experiment was successively conducted. Peptide yield was 29% and half inhibitory concentration(IC50) was 0.53g·L-1.
