Abstract: 
This study investigated the effect of heat treatment combined with acid and alkali on the angiotensin-I-converting enzyme (ACE) inhibitory activity of peptides derived from bovine casein. The free amino group content, color, and cytotoxicity of the peptides were measured under different conditions. When heated at 100 °C in the pH range from 9.0 to 12.0, ACE inhibitory activity was reduced and the appearance of the peptides was significantly darkened. After thermal treatment in the presence of acid and alkali, the free amino group content of ACE inhibitory peptides decreased markedly. High temperature and prolonged heating also resulted in the loss of ACE inhibitory activity, the loss of free amino groups, and the darker coloration of bovine casein-derived peptides. However, ACE inhibitory peptides, within a concentration range of from 0.01 to 0.2 mg/ml, showed no cytotoxicity to Caco-2 and ECV-304 cell lines after heat treatment. This indicated that high temperature and alkaline heat treatment impaired the stability of bovine casein-derived ACE inhibitory peptides.

牛乳酪蛋白源ACE抑制肽的稳定性和毒理特性研究

研究目的:酸碱热处理对牛乳酪蛋白源血管紧张素转化酶(ACE)抑制肽的抑制活性、游离氨基、色泽及其毒理特性的影响。
创新要点:在pH 9.0~12.0的热处理条件下,牛乳酪蛋白源ACE抑制肽的抑制活性降低,色泽加深。热处理后的ACE抑制肽对Caco-2细胞和ECV-304细胞没有毒性作用。
研究方法:以ACE抑制活性、游离氨基、色差值和细胞存活率为检测指标,研究了酸碱热处理对ACE抑制肽的稳定性和毒理特性影响。
重要结论:高温和碱性热处理能破坏酪蛋白源ACE抑制肽的稳定性(见图1~3)。
