摘要
考察了若干酱油样品的血管紧张素转换酶(ACE)抑制活性,发现所试样品均表现出ACE抑制活性,其IC50值范围为0.7405~3.0265mg/mL。样品的ACE抑制活性与其蛋白质降解程度、多肽含量及颜色值无明显相关性,应为多种活性物质综合作用的结果。对我国酱油产品中ACE抑制剂的结构表征可为潜在降血压功能性食品的研发提供指导。
Angiotensin I-converting enzyme (ACE) inhibitory activities of several Chinese soy sauce samples were investigated in this work. it was found that all samples showed ACE inhibitory activities with IC5o values at a range of 0.7405-3.0265 mg/mL. No evident correlation was observed between ACE inhibitory activity and proteolysis degree, peptide content or color value. The total ACE inhibitory activities of the samples may occur from the combined function of various bioactive compounds in soy sauce. It is necessary to clarify the ACE inhibitors in Chinese soy sauce to guide the development of functional food with potential blood Dressure-lowerina properties.
