食品蛋白降血压肽及其酶法制备(一) 总被引:18,自引:1,他引:18
血管紧张素转换酶在血压调节中扮演重要角色。降血压肽通过抑制血管紧张素Ⅰ向血管紧张素Ⅱ的转化以及阻止ACE使激肽失活而起降血压的作用。利用某些蛋白酶对食品蛋白质的定位水解而可产生具有降血压活性的短肽。降血压肽的分离提取是降血压肽生产的难点所在。综述降血压肽的作用机制及其酶法制备和分离提取的研究进展。 相似文献

高血压是人类健康的一大杀手,食品来源的血管紧张素转换酶抑制肽(angiotensin-converting enzyme inhibitory peptides,ACEIPs)因为安全性高、无毒副作用等显著优势而成为合成血管紧张素转换酶(angiotensin-converting enzyme,ACE)抑制剂类降血压药物的潜在替代品。目前已有大量基于体外ACE抑制活性的降血压肽被分离鉴定,但是经过临床研究证实对人体具有明确体内降血压功效的仅有Ile-Pro-Pro(IPP)、Val-Pro-Pro(VPP)和Leu-Pro-Pro(LPP)等少数几种。由于上述3 种三肽最初在酸牛奶中被发现,因此被合称为乳源三肽(以下简称乳三肽),目前国外已有多种基于乳三肽的降血压功能食品上市,其降血压功效已得到了充分验证,但国内尚未发现类似产品。本文就乳三肽的功效、安全性、制备方法和新来源等进行了综述,并对现有关于乳三肽的专利进行了总结,以期为推动我国基于乳三肽第三代降血压功能食品的开发提供参考。 相似文献

Hypertension is one of the main causes of cardiovascular diseases. Synthetic drugs inhibiting ACE activity present high effectiveness in the treatment of hypertension but cause undesirable side effects. Unlike these synthetic drugs, antihypertensive peptides do not show any adverse effect. These peptides are naturally present in some foods and since hypertension is closely related to modern diet habits, the interest for this kind of foods is increasing. Different methods for the purification, isolation, and characterization of antihypertensive peptides in foods have been developed. Nevertheless, there is no revision work summarizing and comparing these strategies. In this review, in vivo and in vitro pathways to obtain antihypertensive peptides have been summarized. The ACE mechanism and the methodologies developed to assay the ACE inhibitory activity have also been described. Moreover, a comprehensive overview on the isolation, purification, and identification techniques focusing on the discovery of new antihypertensive peptides with high activity has been included. Finally, it is worthy to highlight that the quantitation of antihypertensive peptides in foods is a new trend since genotype and processing conditions could affect their presence. Analytical methodologies using mass spectrometry constitute an interesting option for this purpose. 相似文献

Among the bioactive peptides derived from milk proteins, those with blood pressure-lowering effects are receiving special attention due to the prevalence and importance of hypertension in the Western population. A few antihypertensive products based on milk-protein-derived peptides with clinically proven health benefits already exist. This paper reviews the current literature on milk-derived peptides with antihypertensive effects. The structure-activity characteristics of angiotensin converting enzyme (ACE) inhibitory peptides are discussed, as well as their bioavailability, potential physiological affects and the existence of mechanisms of action other than ACE inhibition. The paper also focuses on the technological aspects of the production of bioactive dairy products with antihypertensive peptides, either by fermentation with selected microorganisms or by in vitro-hydrolysis and enrichment. Finally, the stability of the peptides during production and processing is addressed, including the potential interactions with other food components and their influence on peptide bioactivity and bioavailability. 相似文献
