IC50 value of ACE inhibition and peptide yield derived from chicken blood corpuscle hydrolysate obtained fro.m sequential ultrafiltration.
| Sample | α-amino content (mg) | IC50 (mg Leu eqv/mL) | Purification fold | Yield (%) |
|---|---|---|---|---|
| BCH | 317.5 | 0.341a | 1 | 100.0 |
| BCH-I (>30 kDa) | 46.1 | 0.323a | 1.06 | 17.5 |
| BCH-II (1–30 kDa) | 299.3 | 0.259b | 1.32 | 94.6 |
| BCH-III (<1 kDa) | 150.5 | 0.138c | 2.47 | 47.4 |
Value are expressed as mean (n = 3).
Different superscript letters at the column indicate significant difference (P < 0.05).
Abbreviations: ACE, angiotensin I-converting enzyme; BCH, blood corpuscle hydrolysates; IC50, the half maximal inhibitory concentration.
